Radiation protection equipment for radioactive material neutrons
Detection of highly sensitive handheld instrument
1 Scope
This standard applies to the detection and positioning of neutron emission of radioactive substances handheld devices. These highly sensitive instruments are designed primarily for the purpose
Used to detect subtle changes within the normal background caused by the illicit trafficking or unintentional transfer of radioactive material. Highly sensitive instruments allow
Scans large items, such as vehicles or containers. In order to monitor checkpoints or hazardous areas, these instruments are also allowed to be fixed or temporarily fixed
Set unattended use. The instruments specified in this standard also provide methods of detecting photon radiation for personal protection.
This standard does not apply to GB/T 14318-2008 and IEC 61526 radiation protection equipment involved in the performance.
The purpose of this standard is to establish performance requirements, provide examples of acceptable test methods and provide general characteristics, general test conditions, radiation
Characteristics, electrical safety and environmental conditions, used to determine whether the instrument meets the requirements of this standard.
The test results provide government agencies and other users with information on the ability of radiation detectors to reliably detect neutron sources.
Equipment to meet or exceed the technical requirements of this standard performance requirements depend on the correct establishment of appropriate working parameters, the implementation of school
Perform appropriate response testing and maintenance procedures, review conforming quality requirements, and provide formal training to operators.
