137Cs and 134Cs concentrations were determined in the daily diet and foodstuffs in northeastern Poland in the fourth through sixth years after the Chernobyl accident. Intakes, body burdens, and dose equivalents were evaluated in the consecutive years. The data from this and previous work were used for the calculation of the effective half-time of radiocesium in humans. The effective half-time for 137Cs (1.94 y) was similar to that observed after nuclear weapons tests. The effective half-time for 134Cs was 0.98 y. Taking these half-times into account, the whole-body committed dose equivalent for the adult population was estimated to be 256 microSv; it was about 50% higher than that after the nuclear weapons tests.
在切尔诺贝利事故后的第四年至第六年，对波兰东北部日常饮食和食品中的¹³⁷Cs和¹³⁴Cs浓度进行了测定。对连续几年的摄入量、体内负荷和剂量当量进行了评估。将此次及之前工作的数据用于计算人体中放射性铯的有效半衰期。¹³⁷Cs的有效半衰期（1.94年）与核武器试验后观察到的相似。¹³⁴Cs的有效半衰期为0.98年。考虑到这些半衰期，估计成年人群体的全身待积剂量当量为256微希沃特；比核武器试验后的水平高出约50%。
