Physical Properties
Show OT-4
Uranium can be encountered as a solid, liquid, or gas,
depending on its chemical form and surrounding
conditions. Each of these physical forms has particular
hazards. Sometimes, changing the form of uranium can
lead to radioactive decay products accumulating or
becoming concentrated in a particular location, such as on
the surface of a liquid. The result can be an apparent
increase in the radioact ivity.

example of uranium in a solid
form.
The solid forms of uranium are generally the most
stable configurations. The shiny, silvery metal
form is rarely seen except in a workshop when it is
being machined. After machining, the surface
oxidizes, typically within hours, to a hard, black
surface.
After some time, depending on temperature,
humidity, and alloy, the surface may change color
and begin to flake. Orange or yellow colored
