The objective of the report is to provide a biological basis for an assessment of the radiological health problems resulting from human exposure to plutonium, americium and curium. Only limited data are available on the metabolism of these actinides in man and there has been no recorded incidence of serious long-term effects, such as cancer or hereditary effects, which might be related to their incorporation into the body. Long term follow-up studies of workers occupationally exposed to plutonium and other actinides will eventually provide valuable data for improving the basis upon which standards of protection are determined. Current knowledge of the metabolism and effects of plutonium, americium and curium is derived mainly from animal experiments that have been conducted during the last 30 years in laboratories throughout the world. Actinides may enter the body either by inhalation, by ingestion or through wounds. The intact skin is an effective barrier to their entry into the body. After inhalation of actinide dusts the amount deposited in the three regions of the respiratory tract depends on the particle size distribution and is not significantly influenced by the chemical form. Within the first few days after exposure a fraction of the deposited activity is rapidly cleared from the respiratory tract. This is due to transport of particles to the oesophagus by the ciliated epithelium of the upper regions of the respiratory tract and to absorption of soluble actinides into the blood. Experimental studies have shown that for plutonium dioxide the slow component is cleared exponentially with a half-time of retention of about 500 days. For soluble forms of plutonium, such as the nitrate and citrate, and for all compounds of americium and curium, the half-time of retention is about 50 days.
