The International Commission on Radiological Protection released new recommendations in 1990, updating those from 1977. Aimed at incorporating new biological data, improving clarity, and ensuring stability, this Users' Edition presents the main text with essential explanations while omitting detailed annexes for specialists. The index has also been enhanced.
The Task Group of Committee 4 was originally established to produce a report on methods of optimizing radiological protection other than cost benefit analysis.

This report therefore considers various techniques and their application to problems at different levels of complexity.
