Occupational exposures ― Radiation Protection at Swedish Nuclear Power Plants. The Authority's retrospective view

摘要

Occupational dose reduction at nuclear power plants (NPP's) is important. The importance comes not only from the health and safety of the labour force. The associated requirement for a good management system enhances the safety, quality and reliability of the installation and thus the finance of the plant. The Alara concept (As Low As Reasonable Achievable) includes social and economical factors. To strengthen the connection between occupational exposures and economy the nuclear power industry has put a price tag on occupational doses. The utility value of 1 averted manSv has the price of 4 million SEK (i.e. about 440 k EUR). Radiation protection and reactor safety is closely linked. Good radiation protection coupled with good safety practice enhances the positive effects in both areas. A well-planned job results in a job performed accurately with good speed, high quality and security. The need for re-work is minimized and the occupational exposures can be kept low. Radiation protection should always be a natural ingredient in every project at a nuclear power plant.
