Partial results of a large survey of radioactive contamination in Polish forests are presented. All measurements were performed with low-background gamma spectrometers. The measurement method is briefly described. Activities of 137Cs, 134Cs, 125Sb, 106Ru, 144Ce, 154Eu, 155Eu, and 60Co in A0 and A1 layers of forest litter from all over Poland are determined. The geographical distribution of contamination as well as its origin is discussed. Nonuniform composition of the Chernobyl fallout over Poland is confirmed and documented.
本文展示了波兰森林放射性污染大型调查的部分结果。所有测量均使用低本底伽马能谱仪进行。简要描述了测量方法。测定了波兰各地森林凋落物A0层和A1层中¹³⁷Cs、¹³⁴Cs、¹²⁵Sb、¹⁰⁶Ru、¹⁴⁴Ce、¹⁵⁴Eu、¹⁵⁵Eu和⁶⁰Co的活度。讨论了污染的地理分布及其来源。证实并记录了波兰境内切尔诺贝利沉降物成分的不均匀性。
