BS IEC 62484 pdf download – Radiation protection instrumentation — Spectroscopy-based portal monitors used for the de- tection and identification of illicit trafficking of radioactive material
1Scope and object
This International Standard specifies the operational and performance requirements forspectroscopy-based portal monitors used for the detection and identification of illicit traffickingof radioactive material.Spectroscopy-based portal monitors have the ability to detect gammaand neutron radiation and identify gamma-emitting radionuclides that may be present in or onpersons, vehicles, containers, or packages in a static or transient mode of operation.
Operational requirements established by this standard include radiation detection andgamma-emitting radionuclide identification，and those requirements associated with theexpected electrical,mechanical, and environmental conditions when a portal monitor isdeployed.
The object of this standard is to establish performance requirements and to give examples ofacceptable test methods, and to specify general characteristics,general test conditions,radiation characteristics, electrical safety,and environmental characteristics to determine if aportal monitor meets the requirements of this standard.
Special applications, which may include a monitor’s operation under weather conditions or fordetection needs not addressed by this standard, shall require additional testing.
Obtaining operating performance that meets or exceeds the specifications as stated in thisstandard depends upon properly installing the monitor，establishing appropriate operatingparameters， providing security for the monitor，maintaining calibration，implementing asuitable response testing and maintenance program， auditing compliance with qualityrequirements, and providing proper training for operating personnel.
