IEC 62534:2010 pdf free download Radiation protection instrumentation — Highly sensitive hand-held instruments for neutron detection of radioactive material
1Scope and object
This International Standard applies to hand-held instruments used for the detection andlocalization of neutron emitting radioactive material. These instruments are highly sensitivemeaning that they are designed to detect slight variations in the range of usual backgroundthat may be caused by illicit trafficking or inadvertent movement of radioactive material.Thishigh sensitivity allows scanning of larger volume items such as vehicles and containers.These instruments may also be used in fixed or temporally fixed unattended mode to monitorcheck points or critical areas. Instruments addressed by this standard will also provide ameans to detect photon radiation for personal protection.
This standard does not apply to the performance of radiation protection instrumentation whichis covered in lEC 61005 and in lEC61526.
The object of this standard is to establish performance requirements,provide examples ofacceptable test methods, and to specify general characteristics,general test conditions,radiation characteristics,electrical safety,and environmental characteristics, that are used todetermine if an instrument meets the requirements of this standard.
The results of tests performed provide information to government agencies and other users onthe capability of radiation detection instruments for reliably detecting neutron sources.
Obtaining operating performance that meets or exceeds the specifications as stated in thisstandard depends upon properly establishing appropriate operating parameters,maintainingcalibration,implementing a suitable response testing and maintenance program, auditingcompliance with quality requirements,and providing proper training for operating personnel.
