Abstract
The intake of plutonium and americum in the diet of cattle grazing on plutonium contaminated desert range was determined. Daily feed intake of the grazing animals was also determined so that the amount of nuclides ingested daily could be ascertained. Soil ingested by range cattle constituted the principal and possibly only source of ingested plutonium and americum and resulted in a daily intake of 3600–6600 pCi 238Pu, 85,000–400,000 pCi 239Pu, and 11,000–31,000 pCi 241Am daily. Determining transuranic intake by direct measurement and from the composition and contamination of the diet gave identical results.
