Much of the current news is about exposure and fallout.

As a point of information, the Sievert is a unit of “dose equivliant” from exposure to ionizing radiation. It was designed to indicate relative levels of biological effects on living organisms. This measurement technique attempts to take into account the fact that radiation is absorbed differently by different tissues. Usually we speak in terms of humans unless otherwise specified. There are one thousand millisieverts in a sievert (mSv). Zero to 0.25 Sv in a day is considered to have no effect. At up to one Sv people feel sick and more susceptible tissues are damaged. 10 Sv in a day is deadly. As one goes from 1 to 10 Sv in a day things get worse. If a person is esposed to about 6 Sv in a day or more, they won’t die that day. But later, they probably will. Some of the numbers are given in microsieverts, one thousand times less than a millisievert.

In practice, it is common to measure the effects of radiation exposure accumulated over longer time periods. For example, one measures the maximum dose allowed for US radiation-related workers at 50 mSv per year. When mSv is being discussed in most of the text in Ana’s feed (below) you should assume “per year” is meant if not stated, unless otherwise indicated, although in some cases it seems that the measure being used is accumulated to date, which is closer to one fourth of a year.

The question has been raised; Are increased radiation levels across North America sufficient to explain a jump in infant mortality seen since Fukushima, or is that a coincidence? These deaths are concentrated in the region that would have a larger increase of exposure (the west coast). Probably not. Fukushima is so far away. Babies are so … tough and able to withstand toxic insults. And you can’t see radiation, so how bad can it be? Anyway, it ends up that this is probably some very creative data cooking.

One of the main problems at Fukushima at present is the highly radioactive water flooding the structures’ basements. As this water is being pumped around a certain unspecified (probably unknown) amount of radioactive material is being removed from it. In theory, it is possible to remove most of the raidioisotope from the water, but then one is stuck with a pile of radioactive carbon filtering material. An unknown amount of water is leaking from the plant before being contaminated. Efforts to decrease the amount of water being pumped into the plant, and thus becoming contaminated, were tried but resulted in increasing heat in a reactor core.

The other main, continuing story is the growing understanding of how poorly prepared TEPCO was for any sort of disaster at the plant, and how much sweeping under the rug was going on after the earthquake and tsunami.

Meanwhile, efforts continue to reinforce the Number 4 reactor spent fuel rod containment pool which is thought to be too weak to sustain a serious earthquake. Reinforcement is in fact being put in place but it will be several more weeks before that job is done. The water in the containment pool is still quite hot.

Enigmatically, even though the situation at Fukushima improves only very slowly and radiation continues to spew from the plant, the International Atomic Energy Agency no longer sees it as the top story, and it is now supplanted by various IAEA activities and an FAQ about nuclear safety, relegated to page two, as it were, of their web site. The latest update is still JUne 2nd.

Gov’t calls TEPCO radiation exposure standards ‘overly optimistic’ – Mainichi News, June 15

-As the number of workers exposed to high levels of radiation at the crippled Fukushima No. 1 Nuclear Power Plant increases, the government is accusing plant operator Tokyo Electric Power Co. (TEPCO) of slack radiation dose calculations.

-"From the start, the way TEPCO calculates internal radiation exposure has been overly optimistic," a senior Ministry of Health, Labor and Welfare official stated.

-On June 14, Health, Labor and Welfare Minister Ritsuo Hosokawa directed TEPCO to withdraw any worker exposed to more than 100 millisieverts of internal radiation at the disaster-stricken plant, sparking a dispute between the company and the government over radiation dose calculation standards, and delaying the implementation of worker safety-first policies at the plant.

-"We tried to persuade TEPCO to use a rigorous calculation method but the company wouldn’t give in. In fact we’re still at odds over the issue," the labor ministry’s standards bureau told the Mainichi.

-Meanwhile, an attorney for former nuclear plant workers suing TEPCO has called Hosokawa’s 100 millisievert internal radiation exposure limit "too high."

-"That there hasn’t been an internal radiation exposure limit before is also a major problem," said attorney Atsushi Suzuki, adding, "There are cases of multiple myeloma (a cancer of plasma cells, a type of white blood cell) from exposure to 70 millisieverts of annual external radiation, and cases of leukemia caused by just 5 millisieverts. The internal radiation doses Fukushima plant workers have been exposed to just leave me at a loss for words."

Fukushima Workers Tackle Highly Radioactive Water – NPR, June 15

-The challenge is to remove radioactive cesium and other elements that are dissolved in the water.

-The water is being pumped from the flooded basements into holding tanks. From those tanks it will go through a filtration system, something like a charcoal filter, and that captures some of the radioactive material.

-"We can reduce the radioactivity of the contaminated water by a factor of at least a thousand, so it will be significantly less radioactive than when it was coming in." – Jarret Adams, spokesman for AREVA, the French nuclear company working with TEPCO

-Next, the water will run into a system built by the French nuclear company Areva. They use a chemical reaction to turn the dissolved cesium into a solid material.

Japan: Tepco to build sarcophagus over Fukushima reactor – The Telegraph, June 16

-The operator of the Fukushima Dai-Ichi nuclear plant has announced plans to construct a shroud over one of the reactor buildings, a stop-gap measure until a more permanent solution can be found, such as entombing the facility in concrete.

-Tokyo Electric Power Co. will start the construction of a rigid steel frame over the No. 1 reactor on June 27, Yoshikazu Nagai, a spokesman for the company, said.

-The frame, which is being put together off-site, will support polyester fibre panels that have been coated with a resin designed to prevent further radiation leaking into the atmosphere.

-The entire structure will be put together by remotely controlled cranes and other vehicles in order to minimise the amount of radiation the company’s emergency repair crews are exposed to, Mr Nagai said.

Govt sets policy to handle radiation sludge – NHK, June 16

-Radioactive material has been detected in sludge from waste water treatment plants in many areas, mainly in eastern Japan, since the crisis began at the Fukushima Daiichi nuclear power plant.

-The guidelines released by the government’s nuclear disaster taskforce on Thursday say disposal facilities with filters will be used to prevent radiation leaks from fumes that are created when sludge is burned or dissolved.

-The guidelines say sludge measuring over 8,000 to 100,000 becquerels of radiation can be buried in waste disposal sites, after steps are taken to limit nearby residents’ annual exposure to 10 microsieverts or lower.

Monitoring the Monitors – Slate, June 16

-Three months have passed since the Fukushima Daiichi nuclear power plant spun out of control and began spewing radiation into the air and sea. Things have settled down a bit since the first jittery days, when the Chinese went on a salt-buying spree believing the iodine in it would protect them, Californians snatched up potassium iodide pills to counteract thyroid-gland poisoning, and Geiger counters flew off the shelves everywhere. Uncertainty fueled much of the hysteria. And the question remains: Who can we trust to monitor fallout from Fukushima?

Radioactive sushi fear hits markets – Globalpost, June 16

-There is much to admire about the dispossessed fishermen of Tohoku, the region of northeast Japan destroyed by the March 11th tsunami. They will repair their boats, rebuild ports and, in some cases, overcome their fear of returning to the sea.

-But there is one consequence of the disaster over which they are powerless: coastal waters contaminated by the crippled Fukushima Dai-ichi nuclear power plant, and consumers at home and abroad whose love of sushi has succumbed to fear of radioactivity.

-The impact of safety concerns is being felt across Asia, as nervous diners avoid Japanese restaurants, even though no seafood imports have tested positive for dangerous levels of radiation. One restaurant in Taiwan went as far as providing customers with personal Geiger counters to accompany their sushi orders.

Rising water, falling journalism – Bulletin of the Atomic Scientists, June 16

-In Blair, in Council Bluffs, and in my hometown of Omaha — which are all less than 20 miles from the Fort Calhoun Station — some people haven’t forgotten that flooding is what caused the power loss at the Fukushima Daiichi nuclear power plant and the disastrous partial meltdowns that followed. They’re wondering what the floodwaters might do if they were to reach Fort Calhoun’s electrical systems.

-Newspapers and websites all over the country have reported on the flooding and fire at Fort Calhoun, but most articles simply paraphrase and regurgitate information from the NRC and OPPD press releases, which aggregators and bloggers then, in turn, simply cut and paste. Even the Omaha World-Herald didn’t send local reporters to cover the story; instead, the newspaper published an article on the recent fire written by Associated Press reporters — based in Atlanta and Washington.

Mini Nuclear Reactors: TVA Signs Letter Of Intent To Build First In U.S. – HuffPost, June 17

-Pushing ahead with ambitious nuclear plans, the Tennessee Valley Authority signed a letter of intent to become the nation’s first electricity provider to build small modular reactors.

-Spokesmen for the nation’s largest public utility and Babcock & Wilcox Nuclear Energy subsidiary Generation mPower in Charlotte, N.C., said Friday that the letter signed in late May outlines plans for building up to six of the mini reactors at TVA’s vacant Clinch River site west of Knoxville in East Tennessee.

-TVA spokesman Terry Johnson said the utility is pursuing possible development of a single small reactor to start operating by 2020. He said they would be built in pairs. Johnson said the small reactors each could supply enough power to support about 70,000 homes, about one-tenth of a large reactor.

-The cost and who will pay it are not known.

Japan Strains to Fix a Reactor Damaged Before Quake – NYT, June 17

-Three hundred miles southwest of Fukushima, at a nuclear reactor perched on the slopes of this rustic peninsula, engineers are engaged in another precarious struggle.

-The Monju prototype fast-breeder reactor — a long-troubled national project — has been in a precarious state of shutdown since a 3.3-ton device crashed into the reactor’s inner vessel, cutting off access to the plutonium and uranium fuel rods at its core.

-Engineers have tried repeatedly since the accident last August to recover the device, which appears to have gotten stuck. They will make another attempt as early as next week.

-But critics warn that the recovery process is fraught with dangers because the plant uses large quantities of liquid sodium, a highly flammable substance, to cool the nuclear fuel.

Tritium Leaks Found at Many Nuke Sites – ABC News, June 17

-Radioactive tritium has leaked from three-quarters of U.S. commercial nuclear power sites, often into groundwater from corroded, buried piping, an Associated Press investigation shows.

-The number and severity of the leaks has been escalating, even as federal regulators extend the licenses of more and more reactors across the nation.

-Tritium, which is a radioactive form of hydrogen, has leaked from at least 48 of 65 sites, according to U.S. Nuclear Regulatory Commission records reviewed as part of the AP’s yearlong examination of safety issues at aging nuclear power plants. Leaks from at least 37 of those facilities contained concentrations exceeding the federal drinking water standard — sometimes at hundreds of times the limit.

-At three sites — two in Illinois and one in Minnesota — leaks have contaminated drinking wells of nearby homes, the records show, but not at levels violating the drinking water standard. At a fourth site, in New Jersey, tritium has leaked into an aquifer and a discharge canal feeding picturesque Barnegat Bay off the Atlantic Ocean.

Activists urge gov’t to allow animal rescue groups into Fukushima no-entry zone – Japan Today, June 17

-“The suffering that’s happening right now in the Fukushima evacuation zone is staggering,” said Stephanie Feldstein, editor for Change.org. “Born Free USA has given those forgotten animals a voice, and thousands from the Change.org community have stepped up to support them.”

-The Japan Anti-Vivisection Association believes that nearly 675,000 farm animals lived in the evacuation zone prior to the disaster. As few as 1,000 are still alive. The number of cats and dogs is unknown, but as of May 23, only 75 animals had been rescued from the evacuation zone. The rest have been forced to scrounge for what food, water and shelter they can find. Some have even been caught on video roaming the highly radioactive site of the nuclear power plant itself.

-On May 10, the Japanese government eased the barricades, starting a rotation that would allow residents of certain villages to enter for two hours at a time, during which they may crate or tie up their animals outside so government officials can collect them. It is uncertain how quickly that will happen, and there is still no plan for the surviving farm animals.

Tepco begins work to clean coolant water – Japan Times, June 18

-In the short term, the utility hopes to be able to cool down the reactors in a month by circulating the decontaminated water and avoid adding to the current massive amount of radioactive water in the turbine buildings.

-Pipes for the circulating cooling systems have already been installed, so the system can start when the water treatment facility begins operations, according to Tepco.

-The utility resumed the trial run of the system and commenced full-scale operations Friday, after dealing with water leakage a day before.

-The full-scale operation of the new water treatment system is seen as a key step to containing the crisis because it would not only help reduce the polluted water but would create clean water that can be injected into the reactors, whose cooling systems were knocked out by the March 11 earthquake and tsunami.

Tepco report reveals lack of preparedness – Japan Times, June 19

-According to Tepco, plant director Masao Yoshida ordered staff to prepare to lower the pressure in reactor No. 1 by venting steam from its containment vessel at 12:06 a.m. on March 12, more than eight hours after the 9.0-magnitude earthquake and tsunamic knocked out power to the plant and triggered the crisis.

-But Tepco’s records, released Saturday, show it did not have crisis-management manuals that detailed the procedure for manually opening the valves in the event of full power loss.

-Only after the situation had turned into a full-blown crisis did Tepco send workers into a quake-damaged building at the compound to grab the documents needed to check the design and other specifications of the release valve to see if it could be opened manually.

-At that point, Tepco learned that the valve actually had a handle for doing exactly that, the utility said in the report.

-The report, released Saturday by plant operator Tokyo Electric Power Co., is based on interviews of workers and plant data. It portrays chaos amid the desperate and ultimately unsuccessful battle to protect the Fukushima Dai-ichi nuclear plant from meltdown, and shows that workers struggled with unfamiliar equipment and fear of radiation exposure.

-When the Unit 1 reactor lost cooling functions two hours after the quake, workers tried to pump in fresh water through a fire pump, but it was broken.

-A fire engine at the plant couldn’t reach the unit because the tsunami left a huge tank blocking the driveway. Workers destroyed a power-operated gate to bring in the engine that arrived at the unit hours later. It was early morning when they finally started pumping water into the reactor — but the core had already melted by then.

-Eight of the workers who fought the initial crisis were found to have been exposed to high levels of radiation and were removed from plant work.

Japan to open airlock at crippled nuclear plant – CNN, June 19

-Workers at the crippled Fukushima Daiichi nuclear power plant have been cleared to open the No. 2 reactor building’s airlock to ease sauna-like conditions inside, the plant’s owner said Sunday.

-The Tokyo Electric Power Co. said it planned to open the heavy double doors slowly overnight, taking about eight hours to complete the process to avoid disturbing contaminated dust inside the containment building. The company has been trying to filter radioactive particles out of the air inside the building for several days, and Japan’s Nuclear and Industrial Safety Agency approved Friday plans to open the airlock, Tokyo Electric announced.

TEPCO injects water to No.4 reactor storage pool – NHK, June 20

-Tokyo Electric Power Company has been trying to reduce a high level of radiation discovered in the Number 4 reactor of the troubled Fukushima Daiichi nuclear power plant.

-The utility started to inject water into a pool on the top floor which was used for storing large equipment contaminated by radiation on Sunday.

-Tokyo Electric Company discovered that the water level of the pool had dropped to about 1/3 of its capacity as of June 11th.

-TEPCO says the radiation level on the top floor is so high that workers cannot enter, but if the equipment is submerged again, the radiation level will decline enabling operations to restart.

Fukushima Disaster Failures Kept Behind Closed Doors at UN Atomic Meeting – Bloomberg, June 20

-The United Nations nuclear agency’s decision to hold talks about the Fukushima disaster behind closed doors this week ignores the “blindingly obvious” need for greater transparency, said a former official in the U.K. atomic industry.

-“People deserve openness from the industry and its regulators,” Malcolm Grimston, a former information officer at the U.K.’s Atomic Energy Authority who is a London-based policy adviser at Chatham House, said in a June 17 interview. “It is blindingly obvious that greater transparency is needed.”

Rice planted for radiation testing in Iitate – NHK, June 20

-A government-affiliated research center on Monday planted rice in Iitate Village, where all agricultural products are under restricted cultivation. The village is located about 40 kilometers northwest of the plant.

-An average of 2,600 becquerels of radioactive cesium per kilogram of soil was detected in the rice paddy at 15 centimeters depth. The level is below the government’s upper limit of 5,000 for rice paddies. Before contaminated surface soil was removed, the cesium level was four times higher.

-The government will harvest rice from the paddy in October and then conduct tests for radioactive contamination.

Radiation in Japan: Greenpeace Detected Cobalt-60 and High Radiation "Hot Spots" in Fukushima City in Fukushima – EX-SKF, June 20

-Shukan Gendai, a Japanese weekly magazine, had a feature article in early June (for the June 24 Issue) that described the radiation survey in Fukushima City done by Greenpeace on June 7.

-The survey team started the measurement in a park located at 5-minute driving distance from the Fukushima City Hall.

-There is a reason why they [Greenpeace] included the parks in the survey. On April 24, Fukushima Prefecture restricted the use of 5 parks in the prefecture to "1 hour per day" when the radiation exceeding 3.8 microsieverts/hour was detected, which was the national safety limit. Then, the prefectural government removed the restriction on June 6, one day before the Greenpeace survey, saying the later survey showed the radiation within the limit.

-"To begin with, 3.8 microsieverts/hour was calculated, based on the high annual radiation exposure limit of 20 millisievert, and it’s not appropriate. It isn’t just the matter of restricting the use. Parks directly affects the health of children, and should be very carefully monitored", says Greenpeace Japan’s Sato.

-The dirt pile measured 6.3 microsieverts/hour, 1.7 times the national guideline. The staff were surprised at the high number. A pile of dead leaves in the corner measured 4.2 microsievert/hour.

-More serious numbers were to come. The ground surface with weeds behind the restrooms measured 9.1 microsievert/hour, and the area near the water drain at the restroom entrance measured 12.5 microsieverts/hour.

-A local parent who accompanied the Greenpeace staff was surprised.

Pool reinforcement continues at No.4 reactor – NHK, June 20

-The pool contains 1,535 spent fuel rods and its weakened structure makes it vulnerable to future earthquakes.

-TEPCO on Monday completed one stage of the reinforcement that began late last month. 32 iron pillars, each 8 meters tall and weighing 40 tons, were installed beneath the pool on the 2nd floor of the reactor building.

-The utility plans to wrap the pillars in concrete by the end of next month.

-It hopes to lower the temperature of the pool at the No. 4 reactor, which remains high at around 86 degrees Celsius.

Fukushima report shows nuclear power can never be safe and cheap – Damian Carrington’s Environment Blog, Guardian, June 20

-The first "independent" review of the Fukushima nuclear disaster was published today and it does not make reassuring reading.

-Japan is perhaps the most technologically advanced nation on Earth and yet, time after time, the report finds missing measures that I would have expected to already be in place. It highlights the fundamental inability for anyone to anticipate all future events and so deeply undermines the claims of the nuclear industry and its supporters that this time, with the new generation of reactors, things will be different.

-I used quote marks on the word "independent" because the report comes from the International Atomic Energy Association (pdf) (IAEA) which, while independent of Japan, is far from independent from the nuclear industry it was founded to promote. But this conflict of interest only makes the findings of the IEAE’s experts more startling.

Preventing radiation contamination more important than TEPCO’s stock prices – Mainichi Perspectives, June 20

-Some people have suggested that I start to write about something other than nuclear power plants, but with the situation as it is, that’s not going to happen. The crisis at the Fukushima No. 1 Nuclear Power Plant is still not over. Far from it, there are signs that it is getting worse. I can’t stand by and look at the political situation without focusing on this serious event.

-One figure who has entered the public spotlight in the wake of the nuclear crisis is 61-year-old Hiroaki Koide, an assistant professor at the Kyoto University Research Reactor Institute and a controversialist in the anti-nuclear debate. A specialist in nuclear power, Koide has garnered attention as a persistent researcher who has sounded the alarm over the dangers of this form of energy without seeking fame.

-In a TV Asahi program on June 16, Koide made the following comment:

"As far as I can tell from the announcements made by Tokyo Electric Power Co. (TEPCO), the nuclear fuel that has melted down inside reactors at the Fukushima nuclear plant has gone through the bottom of the containers, which are like pressure cookers, and is lying on the concrete foundations, sinking into the ground below. We have to install a barrier deep in the soil and build a subterranean dam as soon as possible to prevent groundwater contaminated with radioactive materials from leaking into the ocean."

-Sumio Mabuchi, an aide to Prime Minister Naoto Kan who is dealing with nuclear power plant issues, holds the same concerns as those expressed by Koide and has sought an announcement on construction of an underground dam, but TEPCO has resisted such a move.

-In my possession, I have a copy of the guidelines that TEPCO presented to the government on how to handle press releases. The title of the document, dated June 13, is "Underground boundary’ — Regarding the press." It is split into five categories on how to handle the announcement of construction of an underground boundary. In essence, it says, "We are considering the issue under the guidance of prime ministerial aide Mabuchi, but we don’t want to be seen as having excess liabilities, so we’re keeping the details confidential."

UK government’s Fukushima crisis plan based on bigger leak than Chernobyl – Guardian, June 20

-The British government made contingency plans at the height of the Fukushima nuclear crisis which anticipated a "reasonable worst case scenario" of the plant releasing more radiation than Chernobyl, new documents released to the Guardian show.

-The grim assessment was used to underpin plans by the British embassy in Tokyo to issue protective iodine pills to expats and visitors. It also prompted detailed plans by Cobra, the government’s emergency committee, to scramble specialist teams to screen passengers returning from Japan at UK airports for radioactive contamination.

-A substantial number of documents were withheld on grounds that they contained "information which, if disclosed, would adversely affect international relations," the government’s civil contingencies team said.

Tokyo area parents’ radiation worries grow with discovery of local ‘hotspots’ – Mainichi News, June 21

-More than three months after the Great East Japan Earthquake and the meltdowns at the Fukushima No. 1 Nuclear Power Plant, Tokyo region residents are becoming increasingly worried over radiation exposure as a number of radioactive "hotspots" have been discovered in and around the capital.

-Local governments are calling for calm, as annual doses of radiation at the hotspots — sites where radiation levels are significantly higher than their surroundings — would not exceed 20 millisieverts as they do in parts of Fukushima Prefecture. Residents are nevertheless calling on their local governments to take some kind of action.

Atom industry body urges cost-effective safety – Reuters, June 21

-Steps to boost atomic safety after Japan’s Fukushima accident must be "cost-effective", an industry body said on Tuesday, a day after the UN nuclear chief suggested power firms could help pay for expanded safety checks.

-John Ritch, director general of the World Nuclear Association, said the industry had been struggling in the last decade to limit capital costs while building a new generation of reactors.

-"In this context, it is crucially important that regulatory actions taken in response to Fukushima have demonstrable benefit arising from any increased costs," he told a major international safety conference, according to a copy of his speech.

-"Focus solely on cost-effective measures," he said.

U.S. sees room to improve nuclear plant safety – Reuters, June 21

-U.S. regulators see room to improve safety at the country’s nuclear power plants even though tests after the Fukushima disaster have shown they are fundamentally sound, the top U.S. watchdog said on Tuesday.

-More than two-thirds of the way through a 90-day task force review to see if the Japanese catastrophe had exposed any issues that needed quick action, a mixed picture was emerging, U.S. Nuclear Regulatory Commission Chairman Gregory Jaczko said.

-"At this point we continue to believe that in the United States the plants operate safely and that the system we have is a robust safety system but we do believe that there are areas where we can make improvements," he told reporters in Vienna.

NPPD: Nuke Plant Could Be Shut Down “In Three Seconds”, Critics Still Worry – Missouri News Horizon, June 21

-Even in the face of key safety questions over the years, some as recently as two months ago, the Nebraska Public Power District (NPPD) insists the 37-year-old Cooper Nuclear Station in Brownville, which sits on the raging Missouri River, is as secure as they come.

-On a scale of 1-10, with 10 being the safest, Alan Dostal who is NPPD’s nuclear expert says, “We are an absolutely safe plant, that’s a 10.”

-Dostal’s comments came during an interview with Nebraska Watchdog on March 29, five days before three workers at Cooper were exposed to radiation. According to the Nuclear Regulatory Commission (NRC) a fuel rod accident triggered alarms that are worn by the workers. NPPD says the incident which is still under investigation did not cause any apparent injuries but was “unacceptable.” The NRC wants “to understand why normal work practices were not followed.”

Temperature at No.3 reactor rises – NHK, June 22

-The operator of the troubled Fukushima Daiichi nuclear power plant says temperatures at the No.3 reactor have started to rise after it reduced the injection rate of cooling water. The cutback is part of efforts to prevent possible overflows of radioactive water at the facility.

-On Tuesday, Tokyo Electric Power Company reduced the amount of fresh water it has been injecting into 3 of the plant’s reactors. The volume was cut back by 0.5 tons per hour at the No. 1 and 2 reactors, and by 1 ton at the No.3 reactor.

-TEPCO says that by 5 AM on Wednesday, temperatures at the upper and lower parts of the No.3 reactor had risen by 4 and 7 degrees Celsius, respectively, from the day before. But it says temperatures at the other 2 reactors remained relatively stable.
