The Guardian reports that radiation levels are rising in the ocean near the Fukushima nuclear plant, and Japanese officials admit they basically have no real solution for the apparent meltdown and/or meltdowns of the four damaged nuclear reactors.
The country’s nuclear and industrial safety agency, Nisa, said radioactive iodine-131 at 3,355 times the legal limit had been identified in the sea about 300 yards south of the plant, although officials have yet to determine how it got there.
Hidehiko Nishiyama, a Nisa spokesman, said fishing had stopped in the area, adding that the contamination posed no immediate threat to humans. “We will find out how it happened and do our utmost to prevent it from rising,” he said.
Good luck with that. The battle to control the reactors could go on for years.
The battle to control the slow-motion meldowns could take years, according to this Reuters article.
Plant operator Tokyo Electric Power Co. has conceded it faces a protracted and uncertain operation to contain overheating fuel rods and avert a meltdown.
“Regrettably, we don’t have a concrete schedule at the moment to enable us to say in how many months or years (the crisis will be over),” TEPCO vice-president Sakae Muto said in the latest of round-the-clock briefings the company holds.
Back to the Guardian piece:
Robert Peter Gale, a US medical researcher who was brought in by Soviet authorities after the Chernobyl disaster, said recent higher readings of radioactive iodine-131 and caesium-137 should be of greater concern than reports earlier this week of tiny quantities of plutonium found in soil samples.
But he added: “It’s obviously alarming when you talk about radiation, but if you have radiation in non-gas form I would say dump it in the ocean.”
Wonderful. The Japanese eat a lot of fish, don’t they?
Radiation measured at a village 40 kilometres from the Fukushima nuclear plant now exceeds a criterion for evacuation, the UN nuclear watchdog said.
And a Japanese nuclear expert has warned crews may have to keep pouring cooling water onto the stricken reactors for years.
Years. That is what multiple sources are now saying. It could take years. So how does it end? We hope for new discoveries that will solve the problem, while the reactors continue to melt down and release radioactive elements into the groundwater and the ocean? Or there is a catastrophic explosion?
Yes, I know the “experts” say that won’t happen, but if workers are going to be struggling with these plants for years, there is inevitably going to be human error. Besides, the “experts” have tried to minimize the dangers all along. Only now is the real truth beginning to come out.
From the Union of Concerned Scientists All Things Nuclear blog:
Today the IAEA has finally confirmed what some analysts have suspected for days: that the concentration per area of long-lived cesium-137 (Cs-137) is extremely high as far as tens of kilometers from the release site at Fukushima Dai-Ichi, and in fact would trigger compulsory evacuation under IAEA guidelines.
The IAEA is reporting that measured soil concentrations of Cs-137 as far away as Iitate Village, 40 kilometers northwest of Fukushima-Dai-Ichi, correspond to deposition levels of up to 3.7 megabecquerels per square meter (MBq/sq. m). This is far higher than previous IAEA reports of values of Cs-137 deposition, and comparable to the total beta-gamma measurements reported previously by IAEA and mentioned on this blog.
This should be compared with the deposition level that triggered compulsory relocation in the aftermath of the Chernobyl accident: the level set in 1990 by the Soviet Union was 1.48 MBq/sq. m.
Thus, it is now abundantly clear that Japanese authorities were negligent in restricting the emergency evacuation zone to only 20 kilometers from the release site.
This is bad, folks. Here is a summary of the health effects of cesium-137:
Like all radionuclides, exposure to radiation from cesium-137 results in increased risk of cancer.
Everyone is exposed to very small amounts of cesium-137 in soil and water as a result of atmospheric fallout. Exposure to waste materials, from contaminated sites, or from nuclear accidents can result in cancer risks much higher than typical environmental exposures.
If exposures are very high, serious burns, and even death, can result. Instances of such exposure are very rare. One example of a high-exposure situation would be the mishandling a strong industrial cesium-137 source. The magnitude of the health risk depends on exposure conditions. These include such factors as strength of the source, length of exposure, distance from the source, and whether there was shielding between you and the source (such as metal plating).
Please note that cesium-137, like plutonium doesn’t occur naturally in the environment. When officials and “experts” talk about “background” radiation, they are talking about elements that have been introduced through nuclear tests and nuclear reactor accidents and bi-products. This “background” radiation wasn’t around before the nuclear age, and I personally don’t believe that it has no effect on us.
From NPR: More radioactive material has been found in foods in Japan.
Yesterday, I asked in a comment what is being done with all the contaminated water that is being removed from the Fukushima reactors. Scarecrow addressed this question today at FDL.
They’ve got hundreds of tons of contaminated water preventing workers from getting close enough to pumps, valves, monitors needed to stabilize conditions. So they have to pump this water out and put it somewhere, but where? There are tanks at/near some units that can hold some of it, but not all, and external temporary storage may allow exposure to the atmosphere. Meanwhile, they must keep pumping more fresh water into the reactors and spent fuel storage pools, while more leaks out.
There are large pools of dangerously contaminated water in the turbine buildings adjacent to each reactor buidling, with more leaking in from somewhere, and few places to put it. Just outside the turbine buildings, there are long, deep trenches nearer the ocean and likely filled with water from the tsunami. But they’re now contaminated with radiation and water leaks from the turbine building.
Where can they put all this water? And given varying degrees of contamination, which water should they put where? For example, should they just pump out the least radioactive water in the trenches/pools and dump it in the ocean?
Believe it or not, some people are suggesting putting the water in large ships and letting them float around in the ocean. And what happens if there is a huge storm and the ships are damaged? Honestly, this gets scarier and scarier every day.
Even worse, today smoke was seen at another nuclear plant owned by Tepco!
The company said smoke was detected in the turbine building of reactor No. 1 at the Fukushima Daini nuclear power plant around 6 p.m. (5 a.m. ET).
Smoke could no longer be seen by around 7 p.m. (6 a.m. ET), a company spokesman told reporters.
The Fukushima Daini nuclear power plant is about 10 kilometers (6 miles) from the Fukushima Daiichi nuclear power plant, where workers have been scrambling to stave off a meltdown since the March 11 earthquake and tsunami knocked out cooling systems there….
After the dual disasters, Japanese authorities also detected cooling-system problems at the Fukushima Daini plant, and those living within a 10-kilometer radius (6 miles) of Fukushima Daini were ordered to evacuate as a precaution.
What next? Something tells me whatever happens next won’t be good.
