1 Scope

This standard specifies the general characteristics, general test methods, mechanical properties, electrical and electronic properties, radiation characteristics, security features and special environment Proper identification and a certificate of property and equipment. 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.

This standard applies to the workplace, released into the environment in gaseous exhaust stream and the environment itself tritium sampling and continuous measurements Equipment, and is suitable for fixed, portable and mobile devices.

Purpose of this standard is to establish general requirements necessary given for continuous monitoring of airborne tritium and/or feasible method and apparatus for sampling Instance. This standard is the complete expansion of existing standards IEC 60761-5, which only applies to the gaseous exhaust stream sampling and monitoring provided tritium Equipment, and this standard to expand coverage to include monitoring of radioactive tritium may cause hazards for all occasions. Device is designed in normal operating conditions and work in emergency conditions (including accident and post-accident period) under. According to the characteristics of emergency conditions, you may need to install dedicated to normal Operating conditions and equipment specially designed for other equipment designed for emergency conditions.

This standard applies to features capable of tritium and tritium monitor sampler.

--- In the workplace, gaseous emissions and environmental point of discharge flow measuring volume activity of tritium and its changes over time;

--- When the tritium volume activity exceeds the preset or preset concentration or total emissions of tritium activity, start the alarm;

--- Determine the total discharge activity within the given time frame of tritium;

--- Air or gas containing tritium sampling and analysis.
