Abstract

In 1977 the ICRU proposed the quantities "effective dose equivalent" and "mean dose equivalent to a particular organ" to be the basis for primary limits in radiation protection. For practical applications, the concept of operational quantities which led to the proposal of the dose equivalent index by the ICRU was introduced. In 1980, at a first European seminar on "Radiation Protection Quantities for External Exposure", the discussion concentrated on the different concepts and on the problems and inconsistencies of the MADE and the index based operational quantities. Since that time, intensive discussion about basic properties and conditions of operational radiation protection quantities has been taking place. This resulted in the publication of ICRU report 39 a few months ago which proposes a new set of operational quantities for use in area and individual dosimetry. Therefore, another seminar on "Radiation Protection Quantities for External Exposure" (Braunschweig, 19 to 21 March, 1985) was organised by the Commission of the European Communities and the Physikalisch-Technische Bundesanstalt, PTB, with the cosponsorship of the International Commission on Radiation Units and Measurements, ICRU, to discuss the new quantities and their implementation, basic theoretical considerations and questions of practical applications and calibration procedures of radiation protection instruments. This volume comprises the proceedings of the seminar, the papers presented and a summary of the concluding discussion. An appendix containing a unified set of conversion functions for the new operational radiation protection quantities has been added. This set of data was requested by the participants at the concluding discussion and is the result of cooperative work of some participants after the meeting. All known data have been included with the aim to provide reliable fluence to ambient dose equivalent conversion factors and corresponding quality factors as a function of energy for photons and neutrons. It may become a basic data set for practical use.
