1. Introduction The purpose of this appendix is to evaluate the potential annval bone doses for adults and children for the six living ratterns considered in the Enewetak Radiological Survey Report (NVO-140). The done doses presented in NVO-140 were calculated for mineral bone for adults as integrated doses for 5-, 10-, 30-, and 7O0-yr periods. Bone and whole- body doses to children were not considered separately because in most eases the doses predicted for adults are usually a good estimate of the dose to children. For example, the external garma contributes similarly 3 a to both adults ani children. ~ : 2 Strontium-90 and os 3To5 contribute over 95% of the food-chain dose and there is evidence to show that doses to : a * . children from ingestion of . sen a Strontium-9O differs from 127 ~ 1 > Cs are usually iess than +these 137 to adults. + : ~“'Cs.

Because of the magnitude of some of the 30-yr intesral bene doses, it was decided that arnual bone doses should be evaluated to indicate the living patterns and agricultural situations which are within FRC cuides for annual bone doses. The more detailed assessment of bone doses is directed at estimating the dose to the critical cell porulation at risk
