This part in GB/T 7165 is applicable to equipments used for simultaneous, delayed or ordinal measuring on all gaseous forms of tritium in gaseous effluents discharged to the environment.
Such kind of equipments has the following functions:
——Monitor on the tritium concentration in gaseous effluents and variation with time at discharge point;
——Startup warning signal when exceed preselected volume activity or total discharge activity.
Such kind of equipments is also applicable to determining the discharged tritium activity in given period.
This standard is to specify special standard requirements, including technical and general test conditions and give the feasible method examples of tritium effluents monitor specified in Chapter 4.
This standard GB /T 7165.1—2005 specifies general requirements, technical characteristic, test methods, radiation characteristic, electrical characteristic, mechanical characteristic, safety characteristic and environmental characteristic. Unless otherwise specified, these requirements are all applicable to this standard.
