The 2007 Recommendations of the International Commission on Radiological Protection


From the publication:

Abstract–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
   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 the following 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.
