Can't say historical, but 1,000 μsv/year is the annual limit / point at which increase cancer risk exists. Fukushima disaster levels were 400,000 μSv/h at peak

Can't say historical, but 1,000 μsv/year is the annual limit / point at which increase cancer risk exists.
Fukushima disaster levels were 400,000 μSv/h at peak. Short term dose of 10,000
μSv causes radiation sickness but probably not death. Beyond that it gets worse.
- mianos 5y agoI can say historically, background is 1,000-3,000 μsv a year depending where you live.
- isomel 5y agoAccording to the Linear-no-threshold model [1], any level of radiation, no matter how small, causes cancer. According to this model, the 1,000 μsv/year of normal background radiation already cause cancer for 1% of people. And any additional dose increase the risk further. [1] https://en.m.wikipedia.org/wiki/Linear_no-threshold_model https://en.m.wikipedia.org/wiki/Linear_no-threshold_model However this model is contested. And the analysis on the cancers incidence in Hiroshima and Nagasaki and Chernobyl seems to indicate that this model is flawed. The exact model is difficult to estimate because of the low number of extra cancer is lost in the noise.
