Abstract

The biological concentration factors for the system pilchard/sea-water for 90Sr and 137Cs are presented and discussed. The 90Sr concentration factor was constant, whereas the concentration factor for 137Cs steadily increased after the Chernobyl accident. An UNSCEAR model was used to describe 90Sr transfer from fallout deposition to pilchards. The transfer coefficient was calculated to be 1.85 x 10(-3) Bq yr kg-1/(Bq m-2). The dose incurred by pilchard consumption was estimated for the Croatian population, the annual collective equivalent dose being less than 0.1 Sv.

摘要

给出并讨论了沙丁鱼/海水系统中90锶和137铯的生物浓缩系数。90锶的浓缩系数是恒定的，而137铯的浓缩系数在切尔诺贝利事故后稳步增加。使用联合国原子辐射效应科学委员会（UNSCEAR）的模型来描述90锶从沉降物沉积到沙丁鱼的转移。计算得出转移系数为1.85×10^(-3) 贝克勒尔·年·千克^(-1)/(贝克勒尔·米^(-2))。估算了克罗地亚人群因食用沙丁鱼而受到的剂量，年度集体当量剂量小于0.1希沃特。
