The results showed that there are some differences between China and ICRP (including some countries in Asia ) of the element of human body, So it needs to provide parameters of the element content for China to compile the parameters of Reference ICRP Man for the future.展开更多

Contents of 32 elements, including 19 newly determined, in 12 categories of food from 12 provinces were analyzed by NAA or AAS technique and the daily intakes of Chinese adult man were estimated and hygienically evaluated. Meanwhile, a typical survey on dietary composition and intake for difference among 4 age groups and between Spring and Autumn was surveyed too. The restflts provide important basis for decision for turther improvement of Chinese diet from hygienic view point and compilation of physiological characteristics of Chinese Reference Man. At the end of this article, the estimated nationwide average intakes for adult man are compared with those for current ICRP Reierence Man.展开更多
