Radiation protection instrumentation - Measurement of personal dose equivalents for X, gamma, neutron and beta radiations - Active personal dosemeters

IEC 61526:2024 applies to personal dosemeters with the following characteristics:

a) They are worn on the trunk, close to the eye, or on the extremities.

b) They measure the personal dose equivalents Hp(10), Hp(3), and Hp(0,07), from external X and gamma, neutron (not for Hp(3)), and beta radiations, and may measure the respective personal dose equivalent rates for the same radiations (for alarming purposes).

c) They have a digital indication. This indication may or may not be attached.

d) They have alarm functions for the personal dose equivalents or personal dose equivalent rates except for hybrid dosemeters. For hybrid dosemeters an alarm function for the personal dose equivalents shall be implemented in the associated readout system.

This document specifies requirements for the dosemeter and, if supplied, for its associated readout system.

This document specifies, for the dosemeters described above, general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and envi-ronmental characteristics.
