Ionising radiation safety

Ionising radiation occurs as either electromagnetic rays: x-rays and gamma rays or particles: alpha and beta particles. It occurs naturally from the radioactive decay of natural radioactive substances but can also be produced artificially.

People can be exposed externally to radiation from a radioactive material or a generator such as an x-ray set or internally, by inhaling or ingesting radioactive substances.

Local rules for use of ionising radiation

The University has strict rules on the use of ionising radiation:
