X-ray safety

The SFU X-ray safety program facilitates and ensures safe use of X-ray Emitting Devices (XEDs) in research, teaching and the environment.

Compliance & oversight


The use of X-ray Emitting Devices (XEDs) is federally regulated by Health Canada, Natural Resources Canada (NRCan) and regulated provincially by WorkSafeBC.

Health Canada is the federal regulatory authority for radiation emitting devices and is responsible for administering the Radiation Emitting Devices (RED) Act and the Radiation Emitting Devices Regulations. The RED Act governs the sale, lease, or importation of all radiation emitting devices in Canada. Natural Resources Canada (NRCan) implements and manages a national certification program.

Radiation safety policy

SFU’s Radiation Safety Program is an integral component of Environmental Health & Safety and is described under SFU’s Policy R20.04

One condition of this policy is to keep occupational exposures to both ionizing and non-ionizing radiation in accordance with the ALARA (As Low As Reasonably Achievable) principle and within the legislated prescribed dose limits.

SFU’s Radiation Safety program, including the use of XEDs, is designed to keep radiation exposures ALARA through: training, implementation of standard operating procedures and protocols to control storage, use and disposal of X-ray generating and emitting equipment.

University Radiation Safety Committee    

The University Radiation Safety Committee, as outlined by the CNSC, acts to oversee and audit the Radiation Safety program. The committee is comprised of researchers with expertise and interest in the use of radiation.


How to prepare for inspections:

XED safety inspections are required to ensure safe operation and regulatory compliance.  ‘Responsible Users’ are required to conduct internal X-ray safety inspections and make the results available to the Radiation Safety Officer.

Internal inspections are conducted by the Radiation Safety staff at SFU on an annual basis. Researchers can prepare for the occasion by inspecting their laboratory, using the inspection form provided below.

Note: Records for user training must be maintained by the Responsible User and be made available for inspection.


Find information on X-ray safety signage.

Important: X-ray signage is mandatory. The sign must be clearly legible and visible at a distance of 2 meters to individuals approaching the room door.

New instrument inventory

X-ray instrumentation registration has been added to SFU’s online laboratory hazard inventory system[AT3] . The inventory allows SFU to better meet important regulatory requirements.

For more visit the laboratory hazard inventory page.


If you use XED, you must be abide by federal record keeping procedures. Consult the XED Record Retention for information regarding XED document retention. Still unsure? Please contact the Radiation Safety Officer.

Radiation protection surveys

Radiation protection surveys of analytical XED’s are intended to determine whether the equipment functions according to applicable design and performance standards and are used and maintained in a way that provides maximum radiation safety to all persons. For more visit specific procedures.
