X-ray radiation information for veterinary medicine staff regarding:

There must be at least one person designated as the Responsible User (Veterinarian, animal health technologist, registered radiology technologist) to undertake responsibility for ensuring radiation safety as outlined in Health Canada Safety Code 28 (p. 9-10), CVBC Checklist for Compliance (p. 5-6) and CVBC Radiation Safety Manual (p.25-29).

 

The purpose of diagnostic x-ray facility protection is to establish and promote quality diagnostic imaging at the x-ray facility while providing protection for workers and lowering patient doses as far as practicable. It centers around quality assurance (QA) and quality control (QC).

Diagnostic x-ray facility protection also requires adequate shielding of the x-ray facility itself. BCCDC has developed a set of easy-to-follow shielding guidelines and templates for various types of x-ray facilities. Advice on shielding matters can be obtained from a qualified Radiation Shielding Design and Assessment Consultant (pdf).

 

Special limits are imposed for pregnant workers as an additional control to enhance the protection of the unborn child. ICRP guidance for pregnant workers can be found in Pregnancy and Medical Radiation (ICRP #84) or as a PowerPoint presentation. The worker should inform the employer once she knows of her pregnancy. Once the worker has declared her pregnancy, the dosimeter reporting period can be changed to 2-week intervals. Special limits apply for the pregnant worker for the remainder of her pregnancy -- in WSBCs Occupational Health and Safety Regulations, is the lesser of:

  • effective dose of 4mSv
  • dose limit specified for pregnant workers under the Nuclear Safety and Control Act or any successor legislation, and the regulations under that Act

RIN 5 - Foetal Dose from Maternal Diagnostic X-ray Examinations document provides guidance for practitioners in the radiology field when addressing embryo dose.

 

The Canadian Nuclear Safety Commission (CNSC) regulates the use of nuclear energy and materials. If applicable, contact the CNSC for regulations, license requirements and management of radionuclides specific to your practice.
