PRELIMINARY STUDIES OF INHALED DUST CONTAINING NEPTUNIUM-237
Technical Report
·
OSTI ID:4819816
Following inhalation of Np/sup 237/ as a contaminant of an industrial dust, about 2% of the total deposited was retained in lungs of rats three weeks after exposure. More than 90% was excreted in feces and about 2% in urine. Liver, kidney, and the carcass retained less than 2%. In 30-day toxicity tests only three deaths occurred in 14 rats at the highest dose level, about 200 picocuries deposited in the lung. Possible kidney damage was indicated in several rats, although histologic changes were marginal. The apparent toxicity was considered to be due to the uranium and fluoride content rather than the Np/ sup 237/ content of the dust. (auth)
