TEPCO discloses radiation map, NHK, April 24:

[…] Radiation levels around the Number 3 reactor building, which was damaged by a powerful hydrogen explosion, are higher than in other locations, and 300 millisieverts per hour of radiation was detected in debris on a nearby mountainside. […]

    How far is this hillside ?
    A click, 2 clicks ?

    They found the fuel pool. Great!!!

      Was there any water in it?

        On this Easter Day, I hope the cores remain submerged in the baptismal, and hope that they will never be resurrected.

        Prayers and miracles may be only ways left to fight this disaster.

        Radioactive Fukushima Plutonium And Strontium Bombarding US West Coast Since March 18th

          Hi, yes, unfortunately that’s the EPA’s I-131 data. Their limit for yap water is 3 pCi per liter. The estimates are the radioactive iodine is dispersed by 10-50 times by the time it gets into the municipal water supply. Even at 3 PCi per liter it’s not safe, but that’s the level the EPA intervenes in their protective action guide. Some cities also have cesium in the tap water (we did). Milk is higher than these numbers in places, but the FDA allows a higher level – so nada, they’re still selling it and letting infants drink it even though lower doses of beta radionuclides are actually more dangerous than higher doses (supra-linear threshold or Petkau effect).

          The EPA isn’t testing regularly, much or for everything. It’s rarely released in a timely way and many times they’ll go offline or delay when they find something.

          It’s also true that plutonium, uranium and strontium from Fukushima are being detected in the US. To my knowledge no one is testing for those in the food chain regionally after rain outs (which is how it disperses), except UC Berkeley on ocassion. France’s CRIIRAD issued an advisory across the Atlantic and said the US West Coast is hit 8-10 times harder implying we should also heed rain advisories, leafy green and fresh milk consumption. I know it’s confusing because it’s really big concerning news, but you aren’t seeing it on the nightly news as you’d expect. We have a lot of tips for exposure prevention here if you’re interested.

            Omg. I hate autocorrect!

            Thanks for all of that info Mothra.
            Much appreciated!

            Thanks for the CRIIRAD information, I’m always looking for possibly less-biased evaluations, now that the EPA and FDA have thrown in the towel on informing the US public. Some things are just too hard to bother with, I guess, and their jobs are among those things.

            By the way, Mothra, I still love you. I’ve changed for the better, it’s real this time. I hope we can meet again in the air above Tokyo and this time I promise never to torch you again.

          yes it’s very real.

    Cheers for Easter!
    FYI, I just learned about the Julian calendar dating production codes on key frozen foods like meat and dairy. I was happy to learn that most of my favorite organic meats and ice creams were produced late last year, so… THEY’RE SAFE!… granted, they only keep frozen for a year from now, but it’s a start.

    100364 means December 31, 2010, for example. The first 2 digits are the last digits of the year they made the food. The other digits are the day out of 365 in the calendar year… i.e., day 364 out of 365 in a year.

    This was helpful for me, but nothing in the learning curve we are all facing!…

  • I just checked the NHK Japanese on the same news. I think NHK English translator screwed up BIG TIME. The debris is not on the nearby mountainside, but it is near the Reactor 3, on the side facing mountains, i.e. west, as opposed to the ocean-side, i.e. east. This is what the Japanese news says (my translation):

    The radiation level is generally high[er] around the Reactor 3 reactor building, which suffered a powerful hydrogen explosion. The debris on the mountain-side [meaning west side] of the Reactor 3 measured 300 milli-sievert/hour.

    激しい水素爆発があった3号機の原子炉建屋周辺は、ほかよりも全般に放射線量が高く、山側のがれきからは1時間当たり300ミリシーベルトの高い放射線量が検出されています

      First it was inside the gates of the facility. Then a half mile. Then a mile. Last I heard reactor #3 exploded to a 3 mile radius. Probably still a conservative estimate. Bad enough though, 3 mile radius includes 3 miles UP. It’s probably much worse.

  • I alerted the NHK World of their mistake.
