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.

Specific procedures

Acquiring and installing X-ray emitting devices (XED)

Important: Please inform Radiation Safety Officer (RSO) of any newly acquired XED.

X-ray equipment must be installed, operated and maintained in accordance with the requirements of the appropriate Health Canada Safety Code. After installation of new XEDs, an inspection should be completed by the installer where device safeguards and dose rates are measured to verify that the device and its set-up is compliant with all federal and provincial regulations.

  • Some of the requirements within the Health Canada Safety Code consist of appointing a Responsible User, conducting radiation surveys, and investigating high exposure incidents
  • An inspection report indicating that the device and its set-up are acceptable shall be obtained by the Responsible User and owner. The report must be forwarded to the RSO prior to the commencement of any work with the device

Selling, donating, or disposing of an XED

  • For sale or donation of XRF devices, the seller or donor must must comply with the RED Act and RED Regulations
  • When disposing of an XRF device, the device owner must observe the instructions provided by the manufacturer in the product manual or contact the manufacturer for information and guidance
  • Please complete the XED Termination form and submit to Radiation Safety

For more detailed information, please refer to Health Canada’s Addendum to Safety Code 32.

Safety Requirements

The primary hazard of analytical XED’s is the generated ionizing radiation and the potential for biological damage as a result of exposure to X-rays. The design safety requirements are specified in the Radiation Emitting Devices Regulations and Health Canada’s Safety Code 32 identifies the requirements for all existing X-ray diffraction (XRD), X-ray fluorescence spectrophotometer (XRF) and cabinet X-ray equipment.

General Safeguards

In order to ensure an acceptable level of protection, please refer to the General Safeguards Plan.

Pre-operational safety checks

To ensure you are in compliance with the pre-operational safety checks, please consult Pre-operational Safety Checks Plan.

Self-inspection Checklist

Self inspection of XEDs should be conducted once per year. Once completed, please e-mail a copy to rad-safety@sfu.ca and maintain records in respective location.

XED Set-up for External Operators

To begin work with an XED in conjunction with an external contractor, the contractor is required to provide the following documentation to the SFU Project Manager at least 3 days prior to starting work:

  • Instrument certification and confirmation that the device complies with the RED act (HS-SC34-2003 Sec 2.2.1)
  • Instrument maintenance records and safety checks (valid for 12 months)
  • Current Leakage Radiation Test for the device (valid for 12 months)
  • Radiation scatter profile (For portable XRF device)
  • A written control and implementation plan to prevent ingress during testing
  • A copy of the contractor's written site-specific emergency procedures
  • Name and contact information of the company's Radiation Safety Officer
  • Standard operating procedure for the instrument
  • Manufacturer training records for the instrumentation

The following documention is required from all SFU employees who intend on operating the device:

  • SFU X-ray safety training certificate
  • Proof of instrument specific training

During operation, the following documentation needs be be kept:

  • Perform and keep a log of regular safety checks
  • Perform and keep a log of regular signage and label checks
  • Usage log

In addition,  the Industrial Radiography Checklist document needs to be completed and filled out by the contractor, the SFU Project Manager, and the SFU Radiation Safety Officer, and sent to the Radiation Safety Officer at rso-info@sfu.ca. Following the conclusion of the work, all records should be kept on site by the Project Manager, and made available to the Radiation Safety Officer during inspection upon request

Emergency Response

Emergency procedures are specific for each facility and should be organized with the assistance of the RSO. Emergency procedures are required to be posted for the following events:

  • Fire
  • Flood
  • Earthquake
  • Equipment malfunction
