At 48, my lifetime dose is >30Rem. Chronic, occupational exposure. Big whoop. These articles written about ‘over-exposures’ are nothing less than ignaorant fear-mongering, unless the exposure is given.
What is ‘the risk’? At occupational levels of 1 Rem per year, there is an increase in the RISK of developing a cancer.
Well, the general population, regardless of risk factors, will have a cancer incidence of ~25%. Not fatal cancers, just cancer of some sort. 1 Rem/yr additional gives an additional .1% per Rem. My ‘risk’ would then be ~28%. Big deal.
All good points, especially; in not knowing the exposure dose(s) pertaining to the original article.
