Control of radioactive substances

Abstract

The possession, use, transport, and disposal of radioactive materials are controlled through regulation to limit exposure of the public and workers. This chapter describes the methodologies employed. Regulation is enacted through a system of notification and licensing, based upon recommendations from the IAEA and ICRP. A competent authority is empowered to permit an organization to hold, use, or dispose of any radionuclide, provided certain conditions are met. These take the form of limits on the quantities of different radioactive materials held, and requirements for security and protection. They require an evaluation of the impact of waste disposal. Methodologies for estimating doses received by critical groups from release of radioactive material into the environment are explained. Minimization of the waste produced and regulation of its disposal are essential components in the overall strategy to protect the environment. Controls over the transport of radioactive materials and medical administrations to patients are considered.
