Abstract
This article presents an analysis of international documents on the justification of monitoring systems in areas where nuclear facilities are located. The main international organization that regulates radiation safety, including requirements for the organization of radiation control and monitoring of radioactive contamination of the environment, is the International Atomic Energy Agency (IAEA). The IAEA Statute authorizes the Agency to establish safety standards to protect health and minimize the consequences to life and property of activities involving the use of radiation technologies. The IAEA safety standards must be used in its own work, and IAEA member states can apply them by incorporating them into their nuclear and radiation safety regulations. Regularly reviewed IAEA safety standards are a key element of the global regime for the protection of people and the environment.
