Description
This work presents recent updates to the international standard IEC 62387 on Dosimetry systems with integrating passive detectors for individual, workplace and environmental monitoring of photon and beta radiation, developed by the International Electrotechnical Commission (IEC) Subcommittee 45B “Radiation Protection Instrumentation”. The second edition was published in 2020, followed by the European version EN/IEC 62387:2022, which incorporates some technical clarifications and editorial corrections.
EN/IEC 62387 is referenced in national regulatory documents or serves as their basis and thus is the foundation for the accreditation or type approval of passive dosimetry systems in individual monitoring services (IMS). Because regulators often require full conformity to this standard, any identified ambiguities, inconsistencies, or needs for further detail must be clarified and, if necessary, incorporated into subsequent revisions. Over the past 15 years, the standard has been continuously refined which will be outlined.
Finally, this work presents examples of recent type-testing results, including the coefficient of variation, non-linearity behavior, and energy and angular dependence. Various environmental and mechanical tests are also discussed.
Standards are developed through international expert groups working on a consensus basis and are approved by the national committees of the IEC member states. The IEC standards balance rigorous detection performance with regulatory requirements and industrial feasibility. They serve as a unified global reference, providing manufacturers and users with standardized requirements and reproducible test methods for compliance testing.
