With respect to
Radiation Protection
, an open source is a source of
Ionising Radiation
in the form of
Radioactive
material which is not encapsulated or otherwise contained. The implication is that open radioactive material can move around and if uncontrolled would lead to
Contamination
. It should be noted that open sources are used extensively in biological research and medicine. See also
