The way I understand it from PSR is that being exposed to electromagnetic rad like a television or cosmic rad from being in a jet plane is very different from ingesting or inhaling man-made radioactive particles over a long period of time in the water, soil and food. Once it gets in the body it lodges in bones, glands/organs and can damage the DNA cells raising a cumulative risk of cancer, because it has a half-life of 30 years. Not everyone will get it, but many will.


Here is what the PSR (physicians for social responsibility) said in March re: rad in food

It's true that ingesting a radioactive particle is different from exposure to "frank" radiation.  However, I'm a little skeptical of their claim that there is a direct and linear relationship between exposure to radioactive isotopes and risk of death.  The real measure is the extent to which you can detect that variation in cancer death rates is likely to be due to exposure rather than chance.  I had thought that below a certain threshold, ingestion of radioactive isotopes (some of which have short half-lives), wouldn't be differentiable from random chance.  Rarely are things like this ever linear.  So when they say:

As the crisis in Japan goes on, there are an increasing number of sources reporting that 100 milliSieverts (mSv) is the lowest dose at which a person is at risk for cancer.  Established research disproves this claim. A dose of 100 mSv creates a one in 100 risk of getting cancer, buta dose of 10 mSv still gives a one in 1,000 chance of getting cancer, and a dose of 1 mSv gives a one in 10,000 risk.   
I'm very skeptical of this kind of claim. In fact, it's probably wrong.  There isn't a linear relationship:

Especially since mSv is a measurement of the relative effect of radiation.  The becquerel is the absolute measure of emission from the radation source.  There's not a direct relationship between becquerels and mSv!

That's one of the reasons why I'm down on nuclear-opponent groups.  Sure the industry may underplay risks, but there is a certain amount of physical verifiability that can be done.  Nuclear opponents seem to massively exaggerate even the little things.

Thanks for the link Mandos. We live, we learn. To add: gov't stats don't fill me with confidence.

Seals washing up on shore with lesions and hair loss. I saw this a few days ago and Reuters posted the pic of the sick seal, I see now they've changed it to something more generic.  http://news.yahoo.com/scientists-test-sick-alaska-seals-radiation-003224466.html

The U.S. and Canada are not testing the fish for radiation, yet MIT is now saying the actual seawater is radiated. http://web.mit.edu/newsoffice/2011/modeling-radioactivity-spread-seawater.html


B.C. west coast doesn't even have a geiger counter yet. http://www.thestar.com/mobile/NEWS/article/1106906

To add - CMAJ - article talks about cover-up and unconscionable risks to Japanese citizens.

Between the Gulf and the West coast, no seafood for me.  :crying [/size]

  A friend out west sent me this link: Post-Fukushima, Japan's irradiated fish worry B.C. experts
