Performance, requirements and testing in individual monitoring

For implementation of the ICRP requirements in practical routine monitoring, a specification is needed with respect to specific performance criteria of the dosimetry system. This includes the dosemeters, and procedures for initial and on-going testing of the dosimetry systems to ensure that the specified criteria are continuously met. Methods are here specified for establishing performance criteria, and satisfying the ICRP overall accuracy requirements for individual monitoring. Furthermore, procedures are given for obtaining numerical values of the uncertainties connected with individual monitoring, and in particular of those related to the energy and angular dependences of the dosemeters. These data are important for the testing of the dosimetry systems. Finally testing programmes in individual monitoring are discussed and four categories of testing are proposed.
