Japan crisis: nuclear workers exposed to 10,000 times more radiation than normal

Concerns over the extent of radioactive contamination in Japan deepened after it emerged that three workers admitted to hospital this week were exposed to radiation levels 10,000 times higher than normal
The news raised fears that the steel and concrete containment around one of the reactors at the crippled Fukushima

Fukushima Reactor No. 3 suffers likely core breach, now leaking water at 10,000 times normal radiation levels
The Fukushima situation took a turn for the worse today as two nuclear repair workers stepped into some water at Reactor No. 3 and suffered severe radiation burns requiring immediate hospitalization. The water, it turns out, measures 10,000 times normal radiation levels, and it appears to be leaking from the core of Reactor No. 3.

If confirmed, this can only mean one thing: A containment breach that now risks the spewing of enormous quantities of radiation into the environment, easily dwarfing the releases from Chernobyl in 1986.

Radioactive fallout from Fukushima approaching same levels as Chernobyl
Because Fukushima continues to leak radiation into the environment, its total radioactive output may yet exceed that of Chernobyl. There's certainly a lot more fuel at Fukushima than there ever was at Chernobyl: 1,760 tons of nuclear fuel versus just 180 tons at Chernobyl.
So Fukushima has ten times the amount of fresh and spent fuel as Chernobyl. And it's still spewing radiation every second. The food and water in Japan is already contaminated, the oceans are radioactive, the air is radioactive, neutron beams are jetting out of the nuclear facility, it's raining yellow water, workers are being hospitalized with radiation burns, and still the nuclear industry says stop worrying... it's all safe!

Japan Requests U.S. To Block Popular Websites
In a recent effort to improve recovery efforts from the recent earthquake and tsunami that hit Japan, the military has decided to block the use of certain websites from its network. Japanese military has reported that these sites are not being blocked due to any content reason but solely to improve the bandwidth necessary for militaristic needs. On Monday the U.S. Pacific Command received a request to block the 13 highest traffic usage sites commonly used on military networks such as YouTube, Google Video, Amazon, eBay, Myspace, and

Breach in reactor suspected at Japanese nuke plant
TOKYO (AP) -- A suspected breach in the reactor at the stricken Fukushima nuclear plant could mean more serious radioactive contamination, Japanese officials revealed Friday, as the prime minister called the country's ongoing fight to stabilize the plant "very grave and serious."
The plant has leaked some low levels of radiation, but a breach could mean a much larger release of contaminants. The possible breach in Unit 3 might be a crack or a hole in the stainless steel chamber of the reactor core or in the spent fuel pool that's lined with several feet of reinforced concrete.

Edano: Voluntary evacuation from 20-30 km advised
The government is advising residents to voluntarily evacuate areas within 20 to 30 kilometers of the crippled Fukushima Daiichi nuclear plant, in view of the severe living conditions in the zone.
Chief Cabinet Secretary Yukio Edano told reporters on Friday that business and distribution in these areas has been harshly disrupted, as an increasing number of people have voluntarily evacuated.

Japan reactor core may be leaking radioactive material, official says
Authorities in Japan raised the prospect Friday of a likely breach in the all-important containment vessel of the No. 3 reactor at the stricken Fukushima Daiichi nuclear power plant, a potentially ominous development in the race to prevent a large-scale release of radiation.
Contaminated water likely seeped through the containment vessel protecting from the reactor's core, said Hidehiko Nishiyama of the Japan nuclear and industrial safety agency.
Three men working inside the No. 3 reactor stepped into water this week that had 10,000 times the amount of radiation typical for that locale, Nishiyama said. That water likely indicates "some sort of leakage" from the reactor core, signaling a possible break of the containment vessel that houses the core.

Japan Quietly Evacuating a Wider Radius From Reactors

3 Reactors May Be Breached, Nuclear Disaster Continues
Kyodo is now reporting that officials at the Fukushima nuclear power plant are injecting freshwater into both reactors#1 and #3. Radioactive water was also found leaking at reactor #2. This means that higher levels of radiation have likely leaked into the atmosphere.
2 of the 3 workers who stepped into the radioactive water were exposed to 2 to 6 sieverts of radiation below their ankles.
“The National Institute of Radiological Sciences, where the three arrived earlier in the day for highly specialized treatment, said the two were exposed to 2 to 6 sieverts of radiation below their ankles, whereas exposure to 250 millisieverts is the limit set for workers dealing with the ongoing crisis, the worst in Japan’s history,” reported Kyodo News.

Japan Nuclear Watch, Friday: Where Did the Water Radiation Come From at Unit 3?
The inability of authorities to get these events under control, and continuing reports of worker exposure, unsafe tap water and produce is naturally increasing the alarm among residents. TV interviews are showing more and more folks saying they want to leave, just get out, but not getting answers they believe from the Japanese Government. Government officials are now saying it’s okay for folks within the 30 kilometer radius to leave voluntarily, but as of Friday, they hadn’t ordered that evacuation. Instead, the Times reports they are quietly encouraging folks to move away. And it’s all complicated by the fact the quakes and tsunami left tens of thousands homeless and requiring massive relief efforts on water, food, shelter medical care.

No, the Amount of Radiation Released from the Japanese Nuclear Reactors is NOT "Safe"
Just as with the Gulf oil spill - where BP, government spokesmen and mainstream talking heads spewed happy talk about how "benign" the dispersants were and how all the oil had disappeared, there is now an avalanche of statements that the radiation is at "safe" doses for everyone outside of the immediate vicinity of Fukushima.
For example, Japanese government call-in advice lines are telling people to simply rinse off any produce covered with radioactive dust.

Fresh coolant injected, high-radiation water leaks from three reactors
Tokyo Electric Power Co. said Friday it has begun injecting freshwater into the No. 1 and No. 3 reactor cores at the crisis-hit Fukushima Daiichi nuclear plant to enhance cooling efficiency, although highly radioactive water was found leaking possibly from both reactors as well as the No. 2 reactor.
The latest efforts to bring the troubled reactors at the plant under control are aimed at preventing crystallized salt from seawater already injected from forming a crust on the fuel rods and hampering smooth water circulation, thus diminishing the cooling effect, the plant's operator said.

High radiation levels at Japanese plant raise new worry
Highly radioactive water has been found at a second reactor at a crippled nuclear power station in Japan, the plant's operator said, as fears of contamination escalated two weeks after a huge earthquake and tsunami battered the complex.
