Testing for excessive radionuclide content in bulk rubble or earth, especially when decommissioning nuclear plant

摘要

A given quantity of bulk material is measured for radioactivity. On exceeding a characteristic radiation level for the given quantity, it is sent to a special reception point for separate storage. Should this level not be reached, the material is designated as uncontaminated and sent to a second reception point,. An Independent claim is included for the equipment for testing the material comprising mechanical handling equipment including a scanner conveyor (28) with detectors (32, 34) measuring radioactivity. A transfer unit (52) redirects the material appropriately into skips.
