Management of Naturally Occurring RadioactiveMaterials (NORM) in Canada

摘要

In Canada, nuclear and radiological regulatory responsibilities are shared between theprovinces/territories and the federal government. The Canadian Nuclear Safety Commission (CNSC)regulates nuclear fuel cycle materials and man-made radionuclides under the Nuclear Safety andControl Act (2000). The provinces and territories regulate NORM arising from industrial activities,not involving the nuclear fuel cycle materials. Present guideline - Canadian Guidelines for theManagement of Naturally Occurring Radioactive Materials (NORM) - was published in 2000 in orderto bring uniformity to the management of NORM-related procedures to provide adequate radiationprotection for workers and the general public. The basic premise of these guidelines is that theNORM-related activities should not be posing any greater hazard than those activities regulated underthe Nuclear Safety and Control Act; these concepts are described in this paper.
