Which organization in Canada is responsible for regulating the use of x-ray devices?

The correct answer is the CNSC (Canadian Nuclear Safety Commission), which is the federal regulatory body responsible for regulating the use of nuclear substances and radiation, including x-ray devices. The CNSC establishes and enforces regulations, licenses facilities, and ensures compliance with safety standards to protect individuals and the environment from radiation risks.

While provincial regulatory bodies play a role in specific local regulations and practices in some cases, the overarching authority for x-ray devices falls under the CNSC, which operates at a national level to address safety and compliance comprehensively. Environment Canada, although involved in environmental protection including some aspects of radiation, does not primarily regulate x-ray devices. The CGSB (Canadian General Standards Board) mainly focuses on the development of standards in various industries and does not have regulatory authority over radiological safety.
