加拿大铀矿资源很丰富,主要集中在安大略省和萨斯喀彻温省。加拿大铀矿资源的特点是:不但有大量含铀量为1～2％的矿床,而且有大量更高品位的铀矿床,平均品位达2～4％,个别达10％。由于品位太高,辐射防护问题尚未完满解决,这些矿床目前只用露天开采。加拿大政府非常重视包括铀矿冶企业的辐射防护监督在内的整个核安全问题。早在1946年加拿大议会就通过了核能监督法,随后又成立了原子能监察局(AECB)来负责辐射监督和核安全监察工作。 Canadian uranium resources are abundant, mainly in Ontario and Saskatchewan. The uranium resources in Canada are characterized by not only a large number of deposits containing 1 to 2% of uranium but also a large number of higher grade uranium deposits with an average grade of 2 to 4% and an individual percentage of 10%. Due to the high grade, the problem of radiation protection has not yet been fully resolved and these deposits are currently used only for open-pit mining. The Canadian government attaches great importance to the entire nuclear safety issue, including the radiation protection supervision of uranium mining and metallurgical enterprises. As early as 1946, the Canadian Parliament passed the Law on Nuclear Energy Supervision, followed by the formation of the Atomic Energy Inspectorate (AECB) in charge of radiation supervision and nuclear safety inspection.
