  • Radioactivity in sea up 7.5 million times

    Radioactive iodine-131 readings taken from seawater near the water intake of the Fukushima No. 1 nuclear plant's No. 2 reactor reached 7.5 million times the legal limit, Tokyo Electric Power Co. admitted Tuesday.

    The sample that yielded the high reading was taken Saturday, before Tepco announced Monday it would start releasing radioactive water into the sea, and experts fear the contamination may spread well beyond Japan's shores to affect seafood overseas.

    When scientists speak of radiation, they speak not only of single doses but also of cumulative doses.

    See for example, this research from the University of Iowa showing that “cumulative radon exposure is a significant risk factor for lung cancer in women".

  • Radioactive water at 5 million times limit found at Japan plant

    The operator of Japan's crippled nuclear power plant said on Tuesday it had found water with 5 million times the legal limit of radioactivity inside a reactor as it struggles for a fourth week to contain the world's biggest nuclear disaster in quarter of a century.

    Underlining the concern over spreading radiation, the government said it was considering imposing radioactivity restrictions on seafood for the first time in the crisis after contaminated fish were found in seas well south of the damaged nuclear reactors.

  • Plant radiation monitor says levels immeasurable

    A radiation monitor at the troubled Fukushima Daiichi nuclear power plant says workers there are exposed to immeasurable levels of radiation.

    The monitor told NHK that no one can enter the plant's No. 1 through 3 reactor buildings because radiation levels are so high that monitoring devices have been rendered useless. He said even levels outside the buildings exceed 100 millisieverts in some places.

    Pools and streams of water contaminated by high-level radiation are being found throughout the facility.

    The monitor said he takes measurements as soon as he finds water, because he can't determine whether it's contaminated just by looking at it. He said he's very worried about the safety of workers there.

  • Japan sets new radiation safety level for seafood

    The new levels coupled with reports that radiation was building up in fish led the government to create an acceptable radiation standard for fish for the first time, and officials said it could change depending on circumstances.

  • Food News You Can Use, the Glow in the Dark Edition

    But back to food. Make no mistake about this – radiation can be taken in not only through breathing it in but also ingesting it. Whatever is out in the fields when the winds in the atmosphere hit the West Coast will be contaminated and I think we should all take the position that given the state budgets and the people in power, no one out there is going to stand over the farmers and orchardists with firearms and cans of gasoline to make sure everything in the fields is destroyed so that none of it gets into the food chain.(You’re especially screwed if you like broccoli)

  • 7.5 mil. times legal limit of iodine in sea

    The operator of the stricken Fukushima Daiichi nuclear power plant says 7.5 million times the legal limit of radioactive iodine 131 has been detected from samples of seawater near the plant.

    Tokyo Electric Power Company, or TEPCO, found on Saturday that contaminated water was leaking from a cracked concrete pit near the No. 2 reactor.

    Experts say this makes it clear that highly radioactive substances from the reactor are flowing into the sea, and that the leak must be stopped as soon as possible.

  • 'No safe levels' of radiation in Japan

    In a nuclear crisis that is becoming increasingly serious, Japan’s Nuclear Safety Agency confirmed that radioactive iodine-131 in seawater samples taken near the crippled Fukushima Daiichi nuclear power complex that was seriously damaged by the recent tsunami off the coast of Japan is 4,385 times the level permitted by law.

    Airborne radiation near the plant has been measured at 4-times government limits.

    Tokyo Electric Power Company, the company that operates the crippled plant, has begun releasing more than 11,000 tons of radioactive water that was used to cool the fuel rods into the ocean while it attempts to find the source of radioactive leaks. The water being released is about 100 times more radioactive than legal limits.

  • Seawater radiation shoots far past limit - Experts fear pollution may affect seafood abroad

  • Radiation: Real Doctors Have Real Things to Say

    Fortunately we have a medical diagnosis of the situation from a doctor who knows something about iodine and the necessity of taking more of it now.

    Dr. David Brownstein, author of Iodine: Why You Need It, Why You Can’t Live Without It, is a friend and a great author of honest medical books. If I could scream with a megaton of force it would be a scream at the orthodox medical establishment to listen to Dr. Brownstein about iodine.

    You have to understand, screaming would be required for they are very hard of hearing over there at the FDA and CDC. Even hearing aids don’t do much good for the higher officials in these organizations.

  • Radioactive scrap metal found in Batumi Port - Georgia!

    The staff of the Batumi port has been evacuated after the experts confirmed radiation in the scrap metal in the port. The brigades of the emergency service are working in the port, the additional groups of experts have been sent from Tbilisi to Batumi. The port has been closed and people are prohibited to enter its territory.

    The harbor has been also closed and people evacuated from the territory.

  • U.S. Sees Array of New Threats at Japan’s Nuclear Plant

    Among the new threats that were cited in the assessment, dated March 26, are the mounting stresses placed on the containment structures as they fill with radioactive cooling water, making them more vulnerable to rupture in one of the aftershocks rattling the site after the earthquake and tsunami of March 11. The document also cites the possibility of explosions inside the containment structures due to the release of hydrogen and oxygen from seawater pumped into the reactors, and offers new details on how semimolten fuel rods and salt buildup are impeding the flow of fresh water meant to cool the nuclear cores.

  • Tepco: May Pump Nitrogen Into No.1 Reactor Due To Possible Hydrogen Build-Up

    "We are thinking of putting in nitrogen gas to prevent a hydrogen explosion, to reduce such a risk," a Tokyo Electric ("Tepco") spokesman told Dow Jones Newswires, adding that there was a possibility that hydrogen gas may be accumulating in the No.1 reactor.

    He added that this would be the first time to use such a measure to tackle the ongoing crisis at the plant.
