1 Scope

This standard specifies the operational and performance requirements based on spectral analysis of portal monitoring system, the system for detecting and identifying illegal traffic Radioactive substances. Based on spectral analysis of portal monitoring system in static or dynamic mode may exist in pedestrians, vehicles, containers and Luggage gamma-ray and neutron radiation detection, the ability of gamma radionuclides were identified.

Operational requirements established in this standard include radionuclide gamma radiation detection and identification requirements, as well as the monitoring system when used with the expected electricity Gas, mechanical and environmental conditions requirements.

The purpose of this standard is to establish a set of performance requirements and gives examples of acceptable test methods and provides the general characteristics of the test strips Member, radiation characteristics, electrical safety and environmental characteristics to determine if the monitoring system meets the requirements of this standard.

For special applications not specified in this standard (such as special climatic conditions or special needs probing, etc.) should be carried out additional tests.

To obtain performance metrics meet or exceed the requirements of this standard, the need to properly install the monitoring system, set a reasonable operating parameters for monitoring the system provides protective measures for regular calibration system, the implementation of a systematic and rational response testing and maintenance schedules, check if you want to meet the quality Demand and operating personnel with appropriate training.
