X-ray_machineSources of ionizing radiation are used in some laboratory areas, including X-ray analytical equipment and radionuclides (e.g. 32P or 14C).

In most cases, such equipment or materials will be required to be under the control of an individual who holds an appropriate Radiation Licence.

Regulations & University policy

The use of sources of ionizing radiation is regulated by the Radiation Protection Act (1965) and Regulations (1982) which is administered by the Office of Radiation Safety in the Ministry of Health.

Minimum requirements for use of sources of ionizing radiation are stipulated in Codes of Safe Practice that can be found on the Office of Radiation Safety website.

The University of Otago Radiation Safety Plan Code of Practice describes the general requirements for areas that use sources of ionizing radiation. As part of these requirements, departments, laboratories or other facilities that use sources of ionizing radiation must also have a Local Radiation Safety Plan that describes the sources of radiation to be used in that specific facility and how these will be managed to ensure the safety of staff, students, patients and the public.

For advice on radiation safety, please contact the Radiation Safety Advisor. (See contact details under Key Contacts).
