4.4 Compliance Enforcement Policy

Laurier assumes responsibility of ensuring to the CNSC that any use of radioactive materials will be used in strict compliance with the Nuclear Safety and Control Act and Regulations and the conditions of the university’s license. To aid in determining the level of risk or immediate danger to health and safety, all compliance violations will be categorized as major or minor violations. All deficiencies must be corrected and reported to the RSC.
