This standard specifies characteristical values, allowing an estimation of possible ionizing radiation on objects, moving during measurement relatively to the detector. Possible objects for a scanning measurement could be vehicles (i.e. railway carriages or ships), container, bulk articles (i.e. bags or luggage items) on a belt conveyor or during dispatching by a loading crane. Such measurements are normally made at frontier crossing points or near crossing trafic scanning rolling vehicles in order to detect unidentified or hidden radioactivites by measuring the increased pulse rate. This standard is based on the method of Bayes-Statistics.
