observed that the radioactivity appears to increase
when uranium is melted. This is because radioactive
decay products, such as radium and thorium, float to
the surface. The density of radium is 5 g/cm3,
compared with 19 g/cm3 for uranium; therefore,
radium floats in molten uranium.
Uranium in contact or solution with water is
common. The primary hazards associated with a
uranium solution are criticality (for enriched
uranium) and spills. Water decreases the quantity of
enriched uranium required for criticality. This topic
will be discussed in Module 105 Criticality Safety.
