[ RadSafe ] xkcd: Relative Radiation Dose chart

[Sandra Matzkin]

Yes, I am aware that this 100 mSv value is considered to be a 
threshold above which the probability of cancer increases linearly 
with dose. I believe it is based on epidemiological studies carried 
out on some populations (Hiroshima and Mayak among them). However, I 
cannot find out how these studies were conducted or which other 
radiological exposed populations were analyzed.

It would be interesting to see both LNT and non-LNT supporters' take on this.
