Novelty. In dissertation reasonability of revision of some normative documents is first scientifically grounded taking into account principles of justification and optimization; new approaches are determined to development systems of radiation safety which have to be represented in a future national legislation; approaches are offered to increasing of radiation safety level in Ukraine.
