Relative Risk Factors Derived From Persons Exposed in Hiroshima
[1] | [2] | [3] | EC = [2] - [3] | RRF = ( EC x 1000 ) / ( [1] x [3] ) |
Notes
Using 1 WLM = 5 rem (the factor suggested by the US National Academy of Sciences) we see that the first four categories given here correspond to 12 WLM , 38 WLM , 83 WLM , and 243 WLM . These are certainly low exposures, in the context of uranium mining.
There is a quadrupling between the last three risk factors (average = 1.7) and the first one (7.0) .
It seems that the extra risk per WLM becomes ever more pronounced as the exposure gets progressively lower.
