Radiation protection instrumentation - Dosimetry systems with integrating passive detectors for individual, workplace and environmental monitoring of photon and beta radiation

This document applies to all kinds of passive dosimetry systems that are used for measuring: - the personal dose equivalent Hp(10) (for individual whole body monitoring), - the personal dose equivalent Hp(3) (for individual eye lens monitoring), - the personal dose equivalent Hp(0,07) (for whole body skin and local skin for extremity monitoring), - the ambient dose equivalent H*(10) (for workplace and environmental monitoring), - the directional dose equivalent H'(3) (for workplace and environmental monitoring), or - the directional dose equivalent H'(0,07) (for workplace and environmental monitoring).

Overview

EN IEC 62387:2022/A11:2022 is a European standard amendment focused on radiation protection instrumentation. Specifically, it addresses dosimetry systems with integrating passive detectors designed for monitoring photon and beta radiation. These systems play a crucial role in individual, workplace, and environmental radiation monitoring. This amendment updates the existing EN IEC 62387:2022 to enhance scope, definitions, testing procedures, and performance requirements for passive dosimetry systems.

This standard is developed by the European Committee for Electrotechnical Standardization (CLC/TC 45B) under CENELEC, and compliance with this document is mandatory for national standards within the EU member countries by April 2023. It covers all passive dosimetry systems used to measure various dose equivalents relevant for radiation protection, including personal, ambient, and directional dose equivalents.

Key Topics

• Scope Modifications
  Extension and clarification of energy ranges for dose equivalents such as Hp(0.07) and H'(0.07) including beta radiation response testing.
  Inclusion of notes regarding tests for dosemeters containing active components, referencing IEC 61526 where applicable.

• Terminology Updates
  Revised definitions for key terms including 'detector', 'indicated value', 'maximum rated measurement time', 'reader', and 'readout' to streamline interpretation and remove ambiguities.

• Performance and Testing Adjustments

  • Updates to angular response tests for workplace and environmental dosimeters, specifying changes for 75° and 90° incidence angles.
  • Clarifications on validity of statistical tests used in dosimetry system performance evaluation.
  • Amendments to testing tables regarding energy levels, angle of incidence, and performance limits for different dose equivalents.

• Environmental and Operational Conditions
  Revised procedures for temperature conditions affecting the reader environment and updated handling of influence quantities during performance verification.

• Measurement Uncertainty and Statistical Parameters
  Changes in statistical parameters in multiple tables (Tables 10 to 15 and F.1), such as coefficient of variation and allowable ranges, ensuring stricter compliance and accuracy in dosimetry readings.

Applications

This standard is essential for manufacturers, calibration laboratories, and radiation protection professionals who work with passive integrating dosimetry systems. It applies to:

• Individual Monitoring
  Ensuring accurate measurement of personal dose equivalents:

  • Hp(10) for whole body exposure
  • Hp(3) for eye lens dose
  • Hp(0.07) for skin and extremity doses

• Workplace Monitoring
  Ambient and directional dose equivalents (H*(10), H'(3), H'(0.07)) to assess radiation levels in occupational environments such as nuclear power plants, medical radiology, industrial radiography, and research facilities.

• Environmental Monitoring
  Passive dosimetry systems for evaluating photon and beta radiation in environments surrounding radiation sources, aiding in regulatory compliance, environmental safety, and public health protection.

The standard guides design, testing, calibration, and quality assurance of dosimeters under various conditions, ensuring reliable radiation dose assessments critical for protection and regulatory compliance.

Related Standards

• EN IEC 62387:2022
  The base standard which this document amends, covering general requirements for radiation protection dosimetry systems with passive detectors.

• IEC 61526
  Specifies performance criteria and testing methods for dosemeters containing active components; referenced for tests not covered in EN IEC 62387.

• ISO 4037-1
  Provides X and gamma reference radiation for calibrating dosimetry systems, often used in conjunction with EN IEC 62387 compliance procedures.

Summary

EN IEC 62387:2022/A11:2022 is a critical amendment that further refines the standards for passive dosimetry systems used in radiation protection. By updating scope, definitions, testing approaches, and performance criteria, it strengthens the reliability and accuracy of dosimetry measurements for individuals and workplaces exposed to photon and beta radiation. Compliance with this standard supports the implementation of effective radiation protection programs aligned with European regulatory requirements.
