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 both individual 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).
This document applies to dosimetry systems that measure external photon and/or beta radiation in the dose range between 0,01 mSv and 10 Sv.

Overview

SIST EN IEC 62387:2022/oprAB:2025 is a European standard issued by CLC (CENELEC) that specifies requirements for radiation protection instrumentation, focusing on dosimetry systems equipped with integrating passive detectors. These systems are designed for individual, workplace, and environmental monitoring of photon and beta radiation. The standard details the application of passive dosimeters to accurately measure various dose equivalents, helping to ensure safety in environments where ionizing radiation is present.

This amendment revises and updates the previous EN IEC 62387:2022 to align with current regulatory and scientific developments, ensuring consistency, improved measurement accuracy, and clearer terminology for users in the field of radiation protection.

Key Topics

• Scope of Dosimetry: The standard covers all types of passive dosimetry systems for measuring:

  • Personal dose equivalent Hp(10) - whole-body individual monitoring
  • Personal dose equivalent Hp(3) - individual eye lens exposure
  • Personal dose equivalent Hp(0,07) - local skin and extremity monitoring
  • Ambient dose equivalent H*(10) - workplace and environmental monitoring
  • Directional dose equivalent H'(3), H'(0,07) - specific directional monitoring in work and environmental settings

• Measurement Ranges: Specifies a dose measurement range between 0.01 mSv and 10 Sv for photon and/or beta radiation.

• Technical Updates:

  • Enhanced definitions and requirements regarding coefficients of variation for different influence quantities.
  • Terminology revisions: “confidence interval” is now “coverage interval,” and “confidence level” becomes “level of confidence”.
  • Updates to technical tables to clarify compliance criteria for different dosimetric types.
  • Title refinements in supporting annexes (e.g., “Coverage intervals” replaces “Confidence limits”).

Applications

SIST EN IEC 62387:2022/oprAB:2025 provides a practical framework for organizations and professionals engaged in radiation protection, including:

• Individual Monitoring: Ensuring compliance with occupational dose limits and safety of radiation workers by accurately tracking personal exposure using passive dosimeters.
• Workplace Monitoring: Maintaining safe environments in workplaces where photon and beta radiation may occur, such as nuclear facilities, hospitals, and research institutions, by regular environmental surveys.
• Environmental Monitoring: Assessing and documenting radiation levels in public or natural environments, contributing to public health, regulatory compliance, and environmental safety.
• Regulatory Compliance: Supporting the implementation and demonstration of regulatory requirements for radiation safety by standardizing measurement systems and results.

The enhancements in this amendment support better decision-making for radiation safety officers, laboratories, regulatory authorities, and environmental agencies by ensuring traceable, reliable, and standard-compliant radiation dose assessments.
