Methods for the practical implementation of the ALARA principle: the CEPN/NRPB joint project

This paper provides an outline of the CEPN/NRPB Joint Project report, and summarizes some of its main features. The fundamental purpose of the Joint Project is to provide clear guidance on the implementation of the ALARA principle. The first part of the paper defines a systematic approach to the practical implementation of the ALARA principle and discusses some of the analytical techniques that can be used to assist in the decision-making process. Part of the work carried out in the Joint Project involved reviewing a number of ALARA case studies covering a range of decision levels, from management and administrative officials to practical field engineers and technicians. As a result of this work it was concluded that most studies fall into two general categories; those related to investment or operational cost appraisal and those related to choices with high social or political profile. The practical issues involved in these two situations are discussed in the second half of the paper
