The soluble citrate complex of americium-241 was orally administered to 20 white Leghorn laying hens daily for two weeks. The yolks, whites, and shells from the eggs were analyzed for their americium content. Yolk was the only egg fraction in which radioactivity was observed. The americium-241 activity in yolks reached a maximum on the 14th day of dosing. Biological half-times of 2.00 plus or minus 0.18 days and greater than 33 days were indicated by the average concentration values of americium-241 in yolks laid after the maximum activity was reached. The hens were serially sacrificed at 1, 10, and 20 days after the final administration of americium-241. Tissue samples were collected and the americium content determined in the edible portions and feathers of the hens. Americium was detected in most tissues shortly after dosing; the main concentrations were found in the liver and the skeleton. The highest concentration per organ (3.03 X 0.001 percent of the dose) occurred in the liver of the hens sacrificed 10 days after final administration of americium-241.
