scope:

It is a task of the national authorities to define those circumstances where radioactive effluent monitoring is a requirement. This standard defines technical requirements for such monitoring, provides some general guidance as to the possible sensitivity and capability of such equipment as may be envisaged and indicates when and where its uses may be practicable. This standard is applicable to equipment for continuous monitoring of radioactivity in liquid effluents during normal operations and during anticipated operational occurrences. Such equipment may, nevertheless, function during accident conditions. This standard does not apply to equipment specifically for use in accident conditions and which may require additional capabilities.
