INTAKES OF RADIOLOGICALLY IMPORTANT TRACE AND MINOR ELEMENTS FROM IRANIAN DAILY DIETS

Abstract

Cesium content and some other more radiologically important mineral elements were measuredby nuclear and non-nuclear analytical methods in Iranian daily diets.This study was extended to a few moresimilar functioning elements such as Sr, Rb, I, K, Mg and Ca as well. Though the 137Cs and otherradionuclieds were not measured in these diets under planned regular investigation in this work, but incomparison with some other backgrounds, the contribution and the impact/effective amount of 137Cs in thedaily diet/total mixed diet may be estimated either by its own part concentrations or by the amount of intakes per person per day, if any of those, is in sufficient quantity of normal range. Nevertheless, the protective role of these minerals in human organs is the main issue of this assessment. The amount of 137Cs and other radionulides in the foodstuff depends upon direct contamination/exposure or via the mineral and organic content of the radionuclides in the soil and environment to be transferred to nutritive species. This effect is also considered.
