The methodology for determination of Pu in soils of the main test sites of the Semipalatinsk Test Site (STS) has been developed. The results of Am and Pu activity determination in soil samples sampled at the main testing sites of the STS are presented. Pu/Am activity ratio is calculated. In most cases, on local sites, Pu/Am activity ratio is in a rather narrow range, which makes it possible to estimate Pu activity based on the results of Am gamma-spectrometric analysis. The accuracy of Pu activity estimation using this method will be about 50%, which is quite enough in most cases.
已开发出用于确定塞米巴拉金斯克试验场（STS）主要试验场土壤中钚的方法。介绍了在 STS 主要试验场采集的土壤样品中镅和钚活性的测定结果。计算了 Pu/Am 活度比。在大多数情况下，在局部地区，Pu/Am 活度比处于相当窄的范围内，这使得可以根据 Am 的伽马光谱分析结果来估算 Pu 的活性。使用这种方法估算 Pu 活性的精度约为 50%，在大多数情况下已经足够。
