This document applies to personal dosemeters with the following characteristics:
They are worn on the trunk, close to the eye, or on the extremities.
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).
They have a digital indication. This indication may or may not be attached.
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.
NOTE 1 When reference is made in this document to "dose", this is meant to indicate personal dose equivalent, unless otherwise stated.
NOTE 2 When reference is made in this document to "dosemeter", this is meant to include all personal dosemeters, unless otherwise stated.
NOTE 3 This document does not cover neutron dosemeters for the Hp(3) measurements up to now.
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 environmental 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.
This document does not cover special requirements for accident or emergency dosimetry, although the dosemeters may be used for this purpose.
This document does not apply to dosemeters used for measurement of pulsed radiation, such as radiation emanating from many medical diagnostic X-ray facilities, linear accelerators or similar equipment.
NOTE 4 Requirements and testing procedure for dosemeters used in pulsed field of ionizing radiation can be found in IEC TS 63050 or IEC TS 62743.
This document does not apply for dosemeters to measure ambient or directional dose equivalent.
