Abstract
The paper presents the results of measurements on tea samples collected during 1962 and 1973-1983 period for their natural radioactivity content. The radioisotopes studied under this programme are radium-226, thorium-228, and potassium-40. Tea was found to contain higher concentration of these radionuclides compared to other foodstuffs having vegetative origin. Interpretation for higher concentrations in tea compared to other foodstuffs is briefly given on the basis of agroclimatic conditions.
摘要
本文介绍了对1962年以及1973年至1983年期间采集的茶叶样本进行天然放射性含量测量的结果。该项目研究的放射性同位素为镭-226、钍-228和钾-40。与其他源自植物的食品相比，发现茶叶中这些放射性核素的浓度更高。基于农业气候条件，简要给出了茶叶中放射性核素浓度高于其他食品的解释。
