1.28μSv/h at Fukushima service area

It’s been over 14 months, but people are living as if nothing happened.

  1. 1 microSv = 0.1 mR
    In the middle of the US, our new “background” is always .20 microSv, and on days when it is windy, or raining, or when jet stream is overhead, it spikes to 0.80 microSv even IN THE HOUSE. It still spikes to 0.60 microSv in the house every few days when I happen to check. And I have an old dial-based Radiation Alert Monitor 4 that picks up only gamma and beta, not alpha. When I first started using it, about 5 years ago, I could never get it to ping … now it pings all the time. Based on various monitoring stations, we know this is much higher on west coast of the US … I have no idea how high, but wouldn’t be surprised if it’s comparable, at times, with the reading reported above, of over 1 microSv. This has become a problem all over the world. People in Brasil and in southern NZ are now reporting readings in air (when it rains) similar to that of US and Canada. Storms form in the ocean, and since the radiation has gone into southern pacific, rain that is picked up contains radiation that is now hitting the southern hemisphere, even. What we might want to start learning is .. in Japan, are measurements like 1.5 and 2 microSv/hour a constant reading? Can you get people to run one hour tests and do an average/minute? Because otherwise, a reading of say 1 microSv is easy to get now in California, Oregon, Washington State, etc., depending on the day’s weather/wind, etc., but at least fortunately, I don’t think we have constant readings that high in continental US, yet. (Although soon after 311, I did get readings of 1.7 microSv/hr.)

  2. Debby: Where are you?! I’m in western Tokyo and I only get between .08 and .14 outside every time I’ve checked.

    Your readings seem off to me. Have you calibrated your device recently? You might want to take it to a univeristy and have someone help you with it.

    safecast.org has some maps with some data on US sites from US volunteers included. Hope this helps. And, from my experience, drinking helps. Just don’t drive….

    1. @anonymous, yes, it was recalibrated. And it is actually LOWER than the EPA CPM data that is updated regularly. 0.40 microSV corresponds to 40 CPM, for example. And EPA data around Milkwaukee WI, for example, has shown spikes, in the last month or so, around 350 CPM!! Which equates to 3.5 microSV! And Iowa EPA data, I noticed, had spikes up to 5.0 microSV, or .5 mR (500 CPM). I am in Wisconsin. And Wisconsin is not nearly as bad as some areas.

      So I just want to EPA radnet, and for Milwaukee, May 19 2012, 200 CPM, or 2 microSV. I’m not picking up nearly this count on my detector, because mine is not expensive or strong enough, like EPAs, which detects more types of elements. If you go to Alexander Higgens’ blog, and click on the EPA Radnet picture, it comes up with statistics for every state. Go to http://blog.alexanderhiggins.com/2011/04/12/realtime-epa-radnet-japan-nuclear-radiation-monitoring-every-us-city-single-page-16511/ and scroll down. I just went to Spokane, Washington, and in January they spiked over 4.5 microSv. But remember, even this EPA site, a government site, tends to underestimate its reports. Many of the locations are blank. Like Chicago, which has been blank ever since I’ve been watching it. Now, of course, the question is … how much contamination is it capturing from Fukushima, and how much from other accidents we’ve had here in the US. And remember, all plants, even those operating “perfectly” release things like tritium all the time … because some elements can’t be blocked by or held in the reactors. But yes … that’s why so many people in the US are sick all the time. And only have the energy enough to sit in front of their t.v. sets at night.

      There are times my detector has “0” … so it isn’t registering high. Tonight my husband brought home blueberries, and he goofed – got California ones. So tonight I tested in house, and outside … readings were about 0.15 with blips to 0.25. Then tested blueberries in kitchen, got spikes up to 0.60 microSV. Since cheap detectors don’t usually pick up readings from food, and I was able to pick up this much, I am NOT eating these!

  3. FUKUSHIMA DIARY – 1.28μSv/h sur une aire de repos autoroutière à Fukushima

    Ça date de plus de 14 mois mais les gens y vivent comme si rien ne s’était passé.

    There are times my detector has “0″ … so it isn’t registering high. Tonight my husband brought home blueberries, and he goofed – got California ones. So tonight I tested in house, and outside … readings were about 0.15 with blips to 0.25. Then tested blueberries in kitchen, got spikes up to 0.60 microSV.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
