Implications of International Recommendations on Monitoring Procedure for Skin Dose Assessment

In 1991, the publication of the third part of the ICRU series of reports on the Measurement of Dose Equivalents resulting from External Photon and Electron Radiations (in which new definitions of the operational quantities will be formulated with some recommendations on their use) and of ICRP publication 60 on New Recommendations of the Commission, modifying the Annual Dose Equivalent Limits and the Quality Factors, will introduce some changes in monitoring procedures for external radiations. This Workshop provides a good opportunity to analyse the implications of these recommendations, combined with those of recent ISO-IEC standards on calibration reference radiations and on instrumentation, in the light of some other recommendations proposed by CEC and other groups of experts. The major points considered concern: (i) Modification of characteristics of radiation protection instrumentation and individual dosemeters (energy and angular response, detection threshold) as a consequence of the ICRP-ICRU recommendations. (ii) Use of calibration procedures adapted to the ICRU quantities. (iii) Introduction of CEC recommendations on accuracy for individual monitoring.
