Report No. 052 - Cesium-137 From the Environment to Man: Metabolism and Dose (1977) This is a members only link.

This Report first outlines the environmental deposition of Cs-137 as fallout from atmospheric nuclear testing. The intent was not to document what has been found, but rather to draw from that experience the information that might be helpful in assessing the relative importance of various food chain pathways and in providing a broad understanding of the metabolism of Cs-137 in man. Second, dosimetry was explored rather fully, to give not only an average dose to the total body but also some idea of the departures from the average that might be expected. In particular, it appears that children, pregnant women, and some persons suffering from certain diseases eliminate cesium more rapidly than does the normal adult, and thus, receive less dose for a given contamination level in the diet. Maximum permissible concentrations (MPC), or equivalently maximum permissible annual intakes (MPAI), of Cs-137 are derived for occupational exposure to soluble compounds. No widespread use of insoluble compounds is known at this time. Fortunately, the wide availability of in vivo counters makes it feasible to follow directly such cases as might occur. While many critical points remain unanswered from the animal experimentation, a moderately large body of information has been accumulated on animals. The most significantt experiments are reviewed in Section 5.
