Principles of radiation protection
The aim of radiation protection is to ensure that radiation is used safely. The principles of radiation protection are based on the recommendations of the International Commission on Radiological Protection (ICRP). The ICRP recommendations are widely accepted internationally and have also been taken into account in the Radiation Act of Finland.
To be acceptable, radiation use must fulfil the following basic principles:
- Principle of justifications
The benefits of using radiation must outweigh the drawbacks. - Principle of optimisation (ALARA principle, As Low As Reasonably Achievable)
Radiation exposure caused by the use of radiation must be kept as low as reasonably achievable. - Principle of limitation
Exposure of radiation workers and individuals of public must not exceed dose limits.
STUK is a regulatory authority controlling use of radiation in accordance with the Radiation Act (592/91). The use and operation of non-ionising radiation and operation where natural sources of radiation can harm is also monitored.
