Radiation protection monitoring technology is used to ensure that the dose limit values for nuclear installation employees and the surrounding population are complied with. Employees of nuclear installations must wear personal dosimeters, which are evaluated monthly by accredited bodies such as Suva or the Federal Office of Public Health (FOPH). Alongside the personal dose, the radiological conditions in and around the nuclear installations are continuously monitored with specific measuring instruments.
As the responsible regulatory authority, ENSI checks whether the legal limits and the regulatory guidelines are complied with in respect of the radiation exposure of personnel and in the vicinity of nuclear installations.
