IEC 62387:2020

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

IEC 62387:2020 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 and in the energy ranges given in Table 1. All the energy values are mean energies with respect to the fluence. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled.

Instrumentation pour la radioprotection - Systèmes dosimétriques avec détecteurs intégrés passifs pour le contrôle radiologique individuel, du lieu de travail et de l'environnement des rayonnements photoniques et bêta

L'IEC 62387:2020 s’applique à toutes sortes de systèmes dosimétriques passifs utilisés pour la mesure de:
- l’équivalent de dose individuel Hp(10) (pour le contrôle radiologique individuel du corps entier),
- l’équivalent de dose individuel Hp(3) (pour le contrôle radiologique individuel des cristallins),
- l’équivalent de dose individuel Hp(0,07) (pour le contrôle radiologique individuel de la peau du corps entier et de la peau locale et des extrémités),
- l’équivalent de dose ambiant H*(10) (pour le contrôle radiologique du lieu de travail et de l'environnement),
- l’équivalent de dose directionnel H'(3) (pour le contrôle radiologique du lieu de travail et de l'environnement), ou
- l’équivalent de dose directionnel H’(0,07) (pour le contrôle radiologique du lieu de travail et de l'environnement).
Le présent document s’applique aux systèmes dosimétriques qui mesurent les rayonnements photoniques et/ou bêta externes dans la plage de dose comprise entre 0,01 mSv et 10 Sv et dans les plages d’énergie données dans le Tableau 1. Toutes les valeurs d’énergie données sont des valeurs moyennes par rapport à la fluence. Les systèmes dosimétriques utilisent habituellement des dispositifs électroniques pour l’évaluation des données et sont donc souvent commandés par ordinateur.
