The International Commission on Radiological Protection issued its last basic recommendations in 1977. The recommendations have been used widely throughout the world to limit exposure of both radiation workers and members of the public to ionising radiation. Supplementary statements to the 1977 recommendations were issued when necessary by the Commission, but developments in the last few years have made it necessary to issue a completely new set of recommendations, officially adopted in November 1990. In publishing these recommendations, the Commission has had three aims in mind: to take account of new biological information and of trends in the setting of safety standards; to improve the presentation of the recommendations; and to maintain as much stability in the recommendations as is consistent with the new information. In order to make the 1990 recommendations more accessible to individuals, this "Users' Edition" contains the main text of the original recommendations, which includes sufficient explanatory material to make clear the underlying reasons for policy makers, but omits the annexes, which contained detailed scientific information on specific points for specialists.The index has been improved and made more comprehensive.

These revised "Recommendations for a System of Radiological Protection" formally replace the Commission's previous, 1990, "Recommendations", and update, consolidate, and develop the additional guidance on the control of exposure from radiation sources issued since 1990. Thus, the present Recommendations update the radiation and tissue weighting factors in the quantities equivalent and effective dose and update the radiation detriment, based on the latest available scientific information of the biology and physics of radiation exposure. They maintain the Commission's three fundamental principles of radiological protection, namely justification, optimisation and the application of dose limits, clarifying how they apply to radiation sources delivering exposure and to individuals receiving exposure.The Recommendations evolve from the previous process-based protection approach using practices and interventions by moving to an approach based on the exposure situation. They recognise planned, emergency, and existing exposure situations, and apply the fundamental principles of justification and optimisation of protection to all of these situations.They maintain the Commission's current individual dose limits for effective dose and equivalent dose from all regulated sources in planned exposure situations. They re-inforce the principle of optimisation of protection, which should be applicable in a similar way to all exposure situations, subject to restrictions on individual doses and risks: dose and risk constraints for planned exposure situations, and reference levels for emergency and existing exposure situations.The Recommendations also include an approach for developing a framework to demonstrate radiological protection of the environment. Keywords include: Justification, Optimisation, Dose limits, Constraints, Reference Levels. This edition does not contain Annex A and Annex B, which are available in the main edition ISBN 978-0-7020-3048-2.
