The object of this International Standard is to define mechanical and o
27、perational character-istics, minimum performance characteristics and general test procedures for personnel monitoring equipment. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For
28、 undated references, the latest edition of the referenced document (including any amendments) applies. This International Standard applies to contamination warning assemblies and monitors used for the monitoring of radioactive contamination on the surface of personnel whether they be clothed or not.
29、 The standard is applicable only to that type of equipment where the user takes no action other than to present himself and/or his hands and feet to the detectors. It is not applicable to equipment where the user or someone else moves detectors over the area to be monitored or the user passes quickl
30、y through the monitor. It is also not applicable to any peripheral equipment which may be associated with a particular type of equipment such as small article monitors.
