描述了一种用于分析环境样品中 241Pu 的纯放射化学方法。给出的数据显示，多种类型和来源的受沉降物污染的海洋样品表现出的 241 Pu/239,240 Pu 比率略高于报道的受沉降物污染土壤的比率，但不能肯定区分。然而，在几个计划或意外的 Pu 释放的样本中，这些比率明显不同，这表明 241 Pu 将成为追踪释放的 Pu 扩散的有用示踪剂。这些数据对于环境 241Am 的来源和增长也有明确的影响。
A purely radiochemical method is described for analysis of241Pu in environmental samples. Data are given showing that fallout-contaminated marine samples, of several kinds and provenances, exhibit241Pu/239,240Pu ratios slightly higher than, but not certainly distinguishable from, those reported for fallout-contaminated soils. Such ratios, however, in samples from several planned or accidental Pu releases, are clearly different, suggesting241Pu will be a useful tracer in following the spread of released Pu. The data have also clear implications for the source, and growth, of environmental241Am.
