Just in time to debunk the US NRC proposal for increasing radiation exposure to the general population from 0.25 mSv (EPA) to 100 mSv: http://www.regulations.gov/#!docketDetail;D=NRC-2015-0057 (Comment Deadline Nov. 19th) is a new study of nuclear workers exposed to cumulative doses with a median average (half-above, half-below) of 4.1 mSv, and an overall arithmetic average (mean) of 20.9 mSv: “Results suggest a linear increase in the rate of cancer with increasing radiation exposure. The average cumulative colon dose estimated among exposed workers was 20.9 mGy (median 4.1 mGy). The estimated rate of mortality from all cancers excluding leukaemia increased with cumulative dose by 48% per Gy (90% confidence interval 20% to 79%), lagged by 10 years“. (See Richardson et. al. below). One Gy is 1000 mSv, in the context of this study, or 10 years worth of the US NRC 100 mSv proposal. This is mortality, that is death…
