The lung neoplasms induced in rats by inhaled, internally deposited 144CeO2 were described and classified using histologic criteria. F344 rats were exposed once or repeatedly by inhalation to 144CeO2 and observed for their life span. There was signif

As a portion of a study to examine how chronic cigarette smoke exposure might alter the risk of lung tumors from inhaled 239puO2 in rats, the effects of smoke exposure on alpha-particle lung dosimetry over the life-span of exposed rats were determine

We investigated the modifying effects of preexisting, bleomycin-induced pulmonary fibrosis on the deposition, retention, and biological effects of inhaled 239PuO2 in the rat. Among rats exposed to similar airborne concentrations of 239PuO2, initial l

The purpose of this study was to obtain information on the {alpha}-particle dose-response relationship of {sup 244}Cm in rats. Rats were exposed briefly by inhalation to graded levels of monodispersive aerosols of {sup 244}Cm{sub 2}O{sub 3} heat-trea

To study the long-term biological effects of repeated inhalation exposure to {sup 239}PuO{sub 2}, 84-day-old rats were exposed to aerosols of {sup 239}PuO{sub 2} to re-establish desired {sup 239}Pu lung burdens of 26, 80 or 250 Bq every other month f

Male Syrian hamsters were scheduled to be exposed by inhalation approximately every 60 days for 1 year (7 exposures) to aerosols of 239PuO2 beginning at 84 days of age. Other hamsters were exposed once when 84 or 320 days of age. Plutonium-239 deposi
