Radiation Safety

Using Radioactive Material and Devices Containing Radioactive Material

The use of radioactive materials and instruments or devices which contain radioactive materials is a highly regulated and controlled area of science in Canada.  The possesion, use and transport of radioactive materials is regulated by the Nuclear Safety Act and enforcement of the act is the responsibility of the Canadian Nuclear Safety Commission (CNSC).   The university is permitted to use radioactive material in accordance with our license with the CNSC.

» Research Policy on the Use of Radioactive Material at Trent

As part of the license with the CNSC  we maintain a work permit authorization system for control of the use of radioactive material.   Personnel who wish to use radioactive material or equipment which contains radioactive material are required to complete a Radiation Work Permit application, attend the Radiation Safety Course and review the Trent University Radiation Safety Program Manual (see below)

To apply for a Radiation Work Permit, complete the application available on the ROMEO research database (available through MyTrent portal)

X -Rays and Devices Which Produce X-Rays

The use of X Rays and devices (Portable or fixed) which emit X-Rays at Trent is governed by the Research Policy on the Use of X ray emitting devices.

» Research Policy on the use of X Rays and X Ray emitting devices

In Ontario the possesion X Ray emitting devices is regulated by the Radiation Protection Division of the Ontario Ministry of Labour.  Specifically,  Regulation 861», which outlines the requirements for registration of all X ray emitting devices.  All X-Ray emitting equipment must have a completent supervisor appointed as responsible for the safe operation of the device.   The supervisor must be knowledgeable about the hazards of X rays and be familiar with the requirements of Regulation 861.   All users of the X ray producing device must take Part 1 of the Radiation Safety Course which discusses the hazards of ionizing radiation and the controls and practices and procedures which will minimize exposure to ioninzing radiation.  If you will be purchasing a device which produces X rays  please contact the Science Facilities Manager at ext. 7061.  Users of X ray emitting devices are responsible for reviewing the Regulation 861 of OH and S act., reading the X Ray Safety Manual» and attending Part 1. of the Radiation Safety Course.  Users can then complete the quiz in the Science Safety Program course, X-ray module, on Blackboard.


Lasers are considered by the Ministry of Labour to be a physical hazard and while no specific regulations exist at this time,  they are covered under the general duty clause within the OH and S act.

Trent University has determined that it will use the ANSI Standard Z 136.1 "Safe use of Lasers" as its operational guide for laser use.

All users of Class 2 lasers and above should take the online Laser Safety course available under the Science Safety Program  Training tab.
