DANSK DS/EN 60761-5 PDF

This part of IEC 60761 is applicable to equipment intended for the simultaneous, delayed or discrete sequential measurement of tritium in any gaseous form in gaseous effluents discharged into the environment. It is applicable to equipment designed to fulfill the following functions: - the measurement of the concentration of tritium in the gaseous effluents at the discharge point and its variation with time; - the actuation of an alarm when a predetermined volumic activity or a predetermined total realeased radioactivity is exceeded.
The equipment may also be used for the determination of the tritium activity discharge over a given period.
The object of this standard is to establish specific standard requirements, including technical characteristics and general test conditions, and to give examples of acceptable methods for the tritium effluent monitors defined in clause 4.
The general requirements, technical characteristics, test procedures, radiation characteristics, electrical, mechanical, safety and environmental characteristics are given in IEC 60761-1.
Unless otherwise stated, these requirements apply in this standard.
