毒性 | The toxic effects of inhaled plutonium vary with the dose, high doses in the dog causing death from radiation pneumonitis and pulmonary fibrosis within a relatively short time, those dogs surviving more than 1000 days dying from neoplasias although fibrosis is apparent. If the form inhaled is the relatively insoluble plutonium oxide, much remains in the lung until transported to the lymph nodes. Soluble forms are transported out of the lung and appear in the liver and skeleton. Injected plutonium citrate behaves as the soluble forms mobilized from the lung, causing primarily bone cancers and, less commonly, liver cancers. |
