Scope

This document 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

Purpose

This document specifies requirements for the dosemeter and, if supplied, for its associated readout system. Usually, a dosemeter is not able to measure all quantities given above. Thus, the dosemeter is only tested with regard to those quantities and types of radiation it is intended to be used for. Other types of radiation are considered as influence quantities which also may have requirements. 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. The only requirements specified for associated readout systems are those which affect its accuracy of readout of the personal dose equivalent and alarm settings, and those which concern the influence of the reader on the dosemeter.
