The metabolism of americium-241 has been studied during an 8-year period in an adult male and his son who, at the ages of 50 and 4 years, respectively, were accidentally and unknowingly contaminated within their home by means of inhalation. Chelation therapy with calcium trisodium pentetate was more effective in enhancing the removal of americium-241 from the child than from the father.

The oral administration of ethyl alcohol enhanced the excretion of 241Am from the liver of a baboon by 2.5 times that of a control animal. After ethanol administration, increases in the total content of 241Am excreted in feces were accompanied by corresponding increases in fecal volumes, although administration of nonalcoholic cathartics would not be expected to produce a similar effect. The effectiveness of ethanol as a decorporating agent may result from its ability to mobilize intracellularly bound 241Am from the liver, thereby making the nuclide more available for metabolic secretory mechanisms occurring via liver-bile-fecal route.
