Current Radiation Levels in Tokyo and Tsukuba (75 km. north of Tokyo)

DEVO - SHRIVEL UP


Bookmark these links I am listing here. Here you can find the current radiation levels in Shinjuku and Tsukuba (75 km. north of Tokyo).


For a comparison of current radiation levels and pre-quake levels in Shinjuku, see here: http://modernmarketingjapan.blogspot.com/2011/03/radiation-levels-in-shinjuku-tokyo-from.html)

Next, updated daily and hourly from the Advanced Industrial Science and Technology Unit in Tsukuba (Tsukuba is between Tokyo and the accident site at Fukushima. It is about 75 kilometers north of Tokyo, and 150 kilometers south of Fukushima). Is an updated hourly summary of radiation measured in microSv/hour.  You can view the daily and hourly radiation level updates here: http://www.aist.go.jp/taisaku/ja/measurement/index.html

Here is an chart from the National Institute of Advanced Industrial Science and Technology's National Metrology Institute of Japan webpage. It shows what typical radiation levels (measured in microSv) are in our daily lives: 






At the bottom left, you see the mark of 190. That's the amount of radiation you get on a one-way flight from Tokyo to New York. Above that, you see the number 2400. That is the amount of radiation that a person gets annually from nature. At the top left is the number 10000. That is annual radiation amount a person who lives in Karapari City in Brazil gets. At the top right, you see 6900, that's the amount of radiation you get from a CT scan. Bottom right? That's 50, the amount a person receives from one X-ray. 

As you can see, there is absolutely no radiation risk in Tsukuba and Tsukuba is much closer to the accident site than is Tokyo. One gets a much bigger dose of radiation flying from Narita to New York. In fact, at 0.05 microSv per hour, you would have to be standing outside in the elements everyday for nearly 40 days straight to equal the amount of radiation you'd receive on just that single one-way flight from Tokyo to New York.

Mike,
Lewis Page, a man after your own heart, I think, with titles like Fukushima scaremongers becoming increasingly desperate
Dead horse long ago flogged down to a mere red stain

and
Fukushima's toxic legacy: Ignorance and fear
Hysteria rages unchecked as minor incident winds down
!
Too bad his boundless optimism does not seem borne out by events, as highly radioactive water, almost certainly from the reactor core is found in increasing quantities around the plant, multiplying the difficulties and slowing down the vitally important task of cooling the reactors. Ballsy writing, tho.

Are there any good websites that document the radiation levels on the US West Coast and Hawaii?

Some of the US Government's EPA monitors are down.

Dear Anonymous... Well, I don't know but I think a good effort with Google search might get you the results you need
