Radiation 10,000 times normal level found in water that hit workers

Quote: Water which three workers were exposed to at the crisis-hit Fukushima Daiichi nuclear plant contained radioactive materials 10,000 times the normal level, plant operator Tokyo Electric Power Co. said Friday.

The finding underlines the possibility that part of the fuel in the No. 3 reactor of the plant or the spent fuel stored in the pool in the reactor building may be damaged.

Reactor workers exposed to radioactive water

Quote: They were working in the basement of the reactor's turbine building when they were irradiated.

Two of the three have been hospitalised due to possible burns caused by beta rays, which can cause major skin damage.

They were not wearing boots at the time so their feet were soaked in the water.

General Atomics division donates radiation monitors to Japan
Company ships Dose-Gard monitors in wake of disaster

BY MIKE FREEMAN, UNION-TRIBUNE
THURSDAY, MARCH 24, 2011 AT 1:51 P.M

A division of San Diego’s General Atomics has donated an unspecified number of wearable radiation monitoring devices to Tokyo Electric Power for workers around the troubled Fukushima Daiichi nuclear power plants...

General Atomics Electronic Systems shipped Dose-Gard Microelectronic Alarming Dosimeters to Japan late last week. The shipment cleared customs on Monday and the monitors were expected to be available for use on Tuesday...

A bit larger than a wristwatch, Dose-Gard monitors measure the cumulative amount of radiation that a person receives during a period of time.The measurements detect radiation amounts as small as a typical chest X-ray to very large amounts that can be fatal.

The devices sound an alarm when radiation exposure has reached a predetermined maximum amount. General Atomics donated all of its current inventory of Dose-Gard monitors to Tokyo Electric Power, the owner of the trouble nuclear reactors...

<<<...>>>

...Matthew Siegel, president of General Atomics Electrical Systems (said)...

“I wanted to contribute and protect emergency responders courageously working at the impacted nuclear plants,” he said. “So I directed my team to pack up everything we had and get it on a plane to Japan.”

Good on General Atomics!

BBM.... What???? They should have been in full protective clothing! Something doesn't add up.

I agree Reannan, Foot problems alone can be painful and exasperating to deal with. But can you imagine what it would be like to have radioactively burned feet??? Oh, those poor workers. I also know that any problem with feet takes longer to heal.

Japan says injured workers exposed to 10,000 times safe radiation

By Mayumi Negishi and Kazunori Takada

TOKYO (Reuters) - Japan said on Friday that workers who suffered burns while trying to cool a crippled reactor were exposed to radiation levels 10,000 times higher than expected, adding evidence that the crucial containment vessel for nuclear fuel had been ruptured.

The No. 3 reactor is also the only one to use plutonium in its fuel mix, which is more toxic than the uranium used in the other reactors.

More to read at the link, I've read a couple stories on this and if true it would be an understatement to call it a setback.

There are many articles this morning about the possibility that the reactor core
may have been breached. The radiation at that facility is 10,000 times above normal.

The story of the Japanese tourists is also in the news. In this article their clothes
and luggage were disposed of and they were treated at a hospital upon arrival in
China.

TOKYO — Japanese officials on Friday began quietly encouraging people to evacuate a larger swath of territory around the Fukushima Daiichi nuclear plant, a sign that they hold little hope that the crippled facility will soon be brought under control.

The authorities said they would now assist people who want to leave the area from 12 to 19 miles outside the crippled plant and said they were now encouraging “voluntary evacuation” from the area. Those people had been advised March 15 to remain indoors, while those within a 12-mile radius of the plant had been ordered to evacuate.

Comprehensive article on workers who received large doses of radiation.
This article includes what they were wearing and more information about
how long they were in the water and the high doses they received.

I think this is getting increasingly worse and because of the situation in the Mid East, it is not front and center in the news. What exactly is the long term plan for this plant and how is it going to ultimatley effect Japan and the whole world? I guess the politics of war and who's going to run for President in 2012 are far more important!!!

I was going to start this morning posting only good things about the recovery of this tragedy and then this news today.

This is reactor #3 the mox fuel reactor and I just can't fathom them abandoning the plant. I heard one news report mention they had dumped 6 times more water on this reactor than any other. They mentioned engineers were wanting to drain this radioactive water from the floor of the containment building. Not sure what they will do with it, maybe tank storage but I haven't heard much about what they intend to do if they determine the reactor core has been breached.

It's sounding like they have a Chernobyl type event going on and this may go down as a level 7 nuclear accident? IMO they are going to have to do something, oh and what happened to the extension cord and water pumping here? I suppose we're not supposed to hear progress on those efforts.

Over 300 engineers reported working on the fix! I know, I'm at a loss as to the best thing to do. I'm not sure if they got water pumping to the core if they could contain it or if they have to encase it in some type of concrete mix to try and contain the radiation. I'm really needing to hear some good news for Japan on the nuclear issue.

Maybe it's marguerita night and being glad we're all safe over here in the U.S.

For one, there will be a dead zone around the plant, extending who knows how far, 70-120 miles maybe. That's just a guess if they don't get this contained. IMO they just can't let this continue.

Radiation Dose Chart ..... easily understood I think, and this is the first time I have seen one like this.

I'm scared for everyone, west coast included - "they" lie, you die, if not now, maybe 20 years down the road. I do not believe ANYONE, experts, talking heads, governments, ANYONE really knows the true dangers of radiation or how it really works.

I am not sure about this, cuz, once again, I'm not an expert.

But, I asked my uncle, he has an engineering degree and nuclear fission is one of his favorite things to research, why they can't just dump a whole bunch of water and concrete mix on it and let it set, or something similar to stop it from melting down.
His response was that they either have to cool it or they have to let it finish melting down before they can attempt any type of containment effort, because even if it is sealed, the nuclear and chemical reactions will still be ongoing. If they try to seal it before stopping the meltdown or letting it finish, it'll just damage any future containment chambers, the same way as it damaged the one around the reactor core (I don't remember which number.)

Scary, scary stuff here.

Three workers trying to cool one of the most critical reactors at the plant were exposed to radiation levels 10,000 times higher than normal, but officials were unable to say if the leak came from the radioactive core due to a crack in the container.

A rupture in the reactor would mean a serious reversal following the slow progress in containing radiation leaks.

The reactor, No. 3 of six, is the only one to use plutonium in its fuel mix which is more toxic than the uranium used in the other reactors.

The government called for a thorough investigation into why such elevated levels of radiation had suddenly come to light.

More than 700 engineers have been working in shifts around the clock to stabilize the plant but they pulled back from some parts when the workers were hurt. Two of the men suffered radiation burns after radioactive water seeped over their boots.

&#8220;The contaminated water had 10,000 times the amount of radiation as would be found in water circulating from a normally operating reactor,&#8221; said Japanese nuclear agency official Hidehiko Nishiyama.

&#8220;It is possible that there is damage to the reactor.&#8221; But Nishiyama later told reporters: &#8220;It could be from venting operations and there could be some water leakage from pipes or from valves, but there is no data suggesting a crack.

Yeah, except for all that radioactive water, there's no sign of a crack....
Remember the video from the woman that worked on cleanup in Chernobyl and Pripyat, and recalled some of the people she worked with stepping in the puddles and the soles of their boots burning off?
This just seems like it will never end for Japan. Lord knows it still isn't over in the areas that were affected by Chernobyl.

EXACTLY. However, smothering it, containing it in a sarcophagus will prevent the radiation from wafting into the air, but no one knows what goes on underneath the sarcophagus. Is it still reacting? If it is, what does that mean?
