One hundred-two samples of colostral milk, collected during spring of 1987, approximately one year after the reactor accident at Chernobyl, were measured for radiocesium contamination. The data showed a normal-type distribution with a mean contamination concentration of 16.4 Bq L-1. A weak correlation of the data to the mothers' diet was established by taking into account four of the main staples in the area. The corresponding transfer coefficient was deduced with a value of fm = 0.06 +/- 0.03 d L-1. The resultant effective dose received by breast-feeding infants was estimated, on the average, as 0.012 mrem d-1.
1987年春季，即切尔诺贝利反应堆事故发生约一年后，采集了102份初乳样本，检测其中放射性铯的污染情况。数据呈正态分布，平均污染浓度为16.4贝可/升。通过考虑该地区四种主要主食，确定了数据与母亲饮食之间的微弱相关性。由此推导出相应的转移系数，fm值为0.06±0.03天·升-1。母乳喂养婴儿平均接受的有效剂量估计为0.012毫雷姆/天。
