X‑Ray Safety


X-Ray Safety

The teaching and research activities at Dalhousie Univeristy employ numerous and varied sources of radiation in the form of nuclear substances and radiation emitting devices. The policies and procedures of the Radiation Safety Program are designed to provide a reasonable and practical standard of safety for the use of radiation emitting devices in the university and to assist in compliance with all applicable regulations and codes as well as the ALARA principle (as low as reasonably achievable). 

Providing a safe and healthy environment in university laboratories is a shared responsibility of all those involved. No set of rules can cover all possible eventualities, hence, workers must excercise sound judgment in all of their work.

The Radiation Safety Officer (RSO) is responsible for the the Radiation Safety Program. At Dalhousie University, x-ray safety applies to various types of x-ray devices, including analytical x-rays, dental x-rays, and industrial radiography. The program is designed to minimize hazards associated with all x-ray sources on univeristy campuses. The Radiation Safety Guide - Analytical X-Ray [PDF - 553 KB] provides specific safety information for analytical x-rays only.

X-Ray Registration

To register an x-ray, please submit the X-Ray Registration Form [PDF - 23 KB] to the RSO. X-ray permits are valid for two years. After two years you must complete the X-Ray Renewal Form [PDF - 24 KB ] to renew your permit. If you need to make changes to your x-ray permit at any time, please submit an X-Ray Admendment Form [PDF - 25 KB].

X-Ray Training

Personnel training on the x-ray units is the responsibility of the Principle Investigator in charge of the device. Training dates must be maintained by the individual PI and must be included on the X-Ray Registration Form. The applicable training dates will be added to the x-ray permit by the Radiation Safety Manager.
