Webduring transport of the thorium nitrate stockpile. Because thorium nitrate is a solid, accidental spills, if any were to occur, could be contained and cleaned up quickly. Therefore, traffic and rail accidents during transportation of the thorium nitrate stockpile would produce no significant adverse impacts on human health or the environment. Webinsoluble thorium compounds are presented in . Table 4-2. Water-soluble thorium compounds include the chloride, fluoride, nitrate, and sulfate salts (Weast 1983). These compounds dissolve fairly readily in water. Soluble thorium compounds, as a class, have greater bioavailability than the insoluble thorium compounds.
