Methodology for Establishing National Strategy for Radiation Safety of Nucleonic Gauges in Cambodian Industry

The International Atomic Energy Agency (IAEA) establishes basic safety standards and provides them for member states to enable the country to safely use radiation sources for beneficial purpose and ensuring that people and the environment are protected. Although Cambodia does not yet operate a nuclear power plant, nuclear research reactor, and a large radiation facilities, we need to regulate radiation protection and manage occupational exposures in our country because we have used some radioactive materials in the field of nuclear medicine, industry, construction, and agriculture etc. The utilization of NGs in Cambodian industry will be rapidly increased in near future due to many advantages. Considering our domestic conditions to industrialize, Cambodian government have to establish a fundamental radiation protection regulatory framework in our country that comply with the IAEA's basic safety standards. Also, we have to a comprehensive mechanism for implement-tation of this framework. Our national regulations relevant to NGs should align with the IAEA's general safety requirement and then the annual occupational exposure should be limited up to 20 mSv. However, an external exposure monitoring all radiation workers of our NG facilities in Cambodia should be in place before we decide this limit of 20 mSv. In this study, we suggest the office of nuclear safety, security, and safeguards under the MME as the government framework for regulating radiation safety. The structure of government responsibility and functions are based on the IAEA/GSR Part 1 and our national conditions. In a word, Cambodia has to formulate our national regulations that are consist with the international nuclear safety standards.
