IEC 61584 pdf download – Radiation protection instrumentation – Installed, portable or transportable assemblies – Measurement of air kerma direction and air kerma rate
1 General
1.1 Scope and object
1.1.1 This International Standard is applicable to installed,portable or transportableassemblies intended to measure
– the direction of an X or gamma radiation source in terms of azimuth and elevation angles,as shown in the schema of figure 1;
the x or gamma air kerma rate at the equipment location;
the attenuation coefficient in a given medium and the related effective energy of the X orgamma beam incident to the equipment location.
The energy range of X or gamma radiation is at least between 50 keV and 1,5 Mev.1.1.2The assemblies considered in this standard comprise at least
– a detection sub-assembly which could include several detectors;
a measuring sub-assembly including a display device,which may be connected together orincorporated into a single assembly or interfaced. This sub-assembly could contain amicroprocessor equipped with an algorithm to process the measured data.
1.1.3 This standard is applicable to measuring assemblies designed for special applications:e.g. high air kerma rate measurements and direction of the plume following a nuclear accidentor，when mounted on a vehicle，to guide it towards the X or gamma sources and to bring itcloser to the intervention place.
1.1.4 National regulation or practice may require the measurement of other quantities than airkerma rate (e.g. ambient dose equivalent rate, other dose rate or exposure rate).This standardmay be applied to performance characteristics of equipment to measure any such quantity.Forexample, the numerical values given for the radiation characteristics apply to any case but the
conventionally true values would be expressed in the appropriate quantity.
1.1.5 This publication specifies general characteristics, general test procedures，electrical,safety and environmental characteristics and the identification certificate for assembliesdefined in this clause.
1.1.6 This standard does not apply to thermoluminescence dosimetry systems or otherpassive integrating devices.
1.1.7 This standard does not provide specifications for measurements of beta radiation andneutrons.
1.1.8 This standard is not applicable to the operating characteristics of indicating or recordingequipments as such (e.g. indicating meters,recorders，alarms etc.). The characteristics ofsuch equipment should be in conformity with the general requirements appropriate to them.
