1 Scope

This standard applies to the workplace, released into the environment in gaseous effluents and the environment itself radioactive noble gas sampling And continuous measurement devices. Monitoring requirements is a continuous and real-time measurement process. This standard includes the sampling process or for real retrospective Laboratory analysis of samples of the acquisition process. The purpose of this standard is necessary to establish general requirements for radioactive noble gases given sampling and monitoring feasible method and apparatus for real example. This standard is the current standard GB/T 7165.3-2008 complete expansion, which applies only in gaseous effluents can be permanently installed Portable and removable radioactive noble gas sampling and monitoring equipment, and expand the coverage of this standard to include monitoring radioactive noble gases All situations can cause radiological hazards. Device is designed in normal operating conditions and in emergency conditions (including accidents and incidents during After) working. According to the characteristics of emergency conditions, you may need to install specially designed for normal operating conditions and equipment earmarked for emergency workers Other equipment condition design. This standard applies to provide the following functionality radioactive noble gas sampler and monitor. --- In the workplace, gaseous emissions and environmental point of discharge flow measuring radioactive noble gas, the volume of activity and over time Variety; --- During normal operating conditions and in emergency conditions (including accident and post-accident period) were measured; --- When the concentration exceeds a preset volume or activity or preset total emission activity, start the alarm; --- To determine the total activity of the gas emissions within a given time range provided different exhaust gas mixture composition information and (or); --- Air or gas sampling and retrospective analysis of an inert gas. Containing the isotope 219Rn, 220Rn and 222Rn radon is a naturally occurring radioactive noble gases, this standard does not consider the measure it. The presence of radon and its progeny may significantly interfere with the correct measurement of the standard covered by an inert gas. This standard specifies the general characteristics of the device, general test methods, mechanical properties, electrical and electronic properties, radiation characteristics, security features, and Environmental characteristics and the proper identification and a certificate. If the device as part of a continuous nuclear facilities radiation monitoring central control system, may Those systems have additional requirements and other relevant standards.
