Ionizing radiation is electromagnetic or corpuscular radiation which is capable of producing ions directly or indirectly in its passage through matter. Sources of ionizing radiation include irradiating apparatus and radioactive substances. It is a legal requirement in Hong Kong that the possession and use of such sources be licensed with the Radiation Board.

The University requires user departments of irradiating apparatus and radioactive substances on campus to follow designated safety rules, meet the relevant legal requirements and designate one radiation protection supervisor each responsible for the management of irradiating apparatus and radioactive substances.
