You will need one of these licences if you intend to operate premises, or use, sell, repair, dispose of, possess, or take part in any other activity that deals with radioactive materials or sources.
A radiation source is a thing that emits or may emit radiation. It can be radioactive material or a radioactive apparatus. Radioactive material is material that spontaneously emits ionising radiation as a consequence of nuclear transformations. A radiation apparatus is an apparatus that produces radiation when energised, or is, if assembled or repaired, capable of producing radiation when energised.
For example, radioactive sources are used by importers / exporters, hospitals, medical practitioners, pharmacists, research institutions, manufacturers, geological surveyors, universities and oil rigs.
