IEC 61005-2003 pdf – Radiation protection instrumentation – Neutron ambient dose equivalent (rate) meters.
1 Scope and object This International Standard is applicable to all assemblies designed to measure the ambient dose equivalent (rate) due to neutron radiation of energy up to 16 MeV, and which comprise at least: a) a detection assembly, which may, for example, consist of a detector probe for thermalised neutrons and an arrangement of moderating and absorbing media surrounding the detector; b) a measuring assembly with a display for the measuring result, which may be incorporated into a single assembly or connected by means of a flexible cable. The requirements given below pertain to assemblies as defined in the first paragraph. It is acceptable, however, to use assemblies, which do not meet the requirements below when such requirements are not deemed essential for a given purpose. In such cases, the requirements to be applied to the assemblies should be specified by agreement between the manufacturer and the purchaser, but the methods of determination of the characteristics of the assemblies should conform to this standard. No tests are specified in this standard for the performance requirements of the assemblies in pulsed radiation fields, and it is to be considered that an assembly designed to meet this standard may not be suitable for use in such fields. The object of this standard is to specify requirements for the performance characteristics of neutron ambient dose equivalent (rate) meters, and to prescribe the methods of testing in order to determine compliance with this standard. This standard specifies, for the assemblies described in the first paragraph, general characteristics, general test procedures, radiation characteristics, electrical, mechanical, safety and environmental characteristics, and also the identification certificate. Requirements and test procedures are also specified for the alarm performance of the dose equivalent (rate) meters, which are equipped with alarm provisions.

For the purpose of this International Standard, the following definitions apply. 3.2 Dosimetric terms and quantities NOTE The system of radiation units used in this standard is the SI system. Multiples and sub-multiples of the units are used in accordance with SI. The specific radiation protection quantities and units are used in accordance with ICRU 51 (1993) and ISO 8529-1. In addition, for time, the units hour (h) and minute (min) are used.
