Module 101 Properties of Uranium
Lesson Plan
Instructor's Notes
Past industrial experience has proven that if there is
a long-term exposure of small amounts of uranium
(chronic exposure), the radiological effects are the
primary biological concern. In fact, for chronic
exposures, a development of tolerance against the
toxicological effects may occur. The principal
radiological hazard associated with uranium is due
to the relatively high energy alpha particles its
radionuclides and daughters emit. A chronic
exposure to these radionuclides result in an
increased risk of cancer, typically in the bones,
kidney, and lungs, since these are the organs where
uranium is deposited.

Chemical Reactivity
The chemistry of uranium is complicated. For

example, uranium forms several oxides: UO, UO2
UO3, and UO4. In general, a sample of uranium
oxide will include a mixture of several of these. For
example, U3O8 is sometimes written as
(UO2)2(UO3).
