Employee radiation exposure in nuclear power plants
The Radiation and Nuclear Safety Authority monitors the exposure to radiation of nuclear power plant employees in order to ensure that the dose limits of employees due to radiation work are not exceeded.
The effective dose to which employees are exposed during radiation work cannot exceed 20 millisieverts (mSv) per year (Government Decree on Ionizing Radiation 1034/2018). The highest radiation dose to which Finnish nuclear power plant workers were exposed in 2014 was 14.0 mSv.
The Radiation and Nuclear Safety Authority also monitors the collective (combined) radiation dose to which nuclear power plant employees are exposed. The collective dose provides information on the success of radiation protection for employees at facilities, among other things. The length of the annual maintenance of power plants and significant tasks from a radiation protection viewpoint affect the size of the annual collective dose.
The collective (combined) doses of nuclear power plant employees at the Loviisa plant between 1977 and 2021.
The collective (combined) doses of nuclear power plant employees at the Olkiluoto plant between 1980 and 2021.
