1 Scope and object
This International Standard applies to alarming radiation detection instruments that are pocket-sized, carried on the body and used to detect and indicate the presence and general magnitude of penetrating ionizing radiation, including photons and/or neutrons.
Personal Radiation Devices (PRD) alert the user to the presence of a source of radiation that is distinctly above the measured average local background radiation level. They are not intended to provide a measurement of dose equivalent rate.
The object of this standard is to describe design and functioning criteria along with testing methods for evaluating the performance of instruments for detection of illicit trafficking of radioactive material (for example, for border radiation monitoring). These instruments may be used in extreme environmental conditions.
This standard does not apply to the performance of radiation protection instrumentation covered in IEC 60846, IEC 61 526, and IEC 62327.
The performances of the PRD with respect to neutrons may be degraded and not warranted when they are used in other conditions than on the body.
