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. |
