The table provides dose factors in rem/picccuries/day. on NRPB (1987) which provides factors in Sv/Bq (= 3.7 x rem/picocurie), and with ICRP recomendations (ICRP 1986, 1987). These factors allow for the radionuclide absorbed from the gut, its distribution and residence time in absorption and effectiveness of its radiation in the body, and its rate of >/ Committed effective dose equivalent (whole-body dose). Other doses are the body of a standard man, each weighted by the risk resulting from a wit tissue as compared to the risk from a uit dose to the whole body. c/ E45 signifies: x10°5.
