The radiological concept of clearance can be defined as the release of radioactive materials or buildings from any further regulatory control applied for radiological protection purposes by the competent body. It is generally based on the assumption that, following clearance, any potential radiological exposure of the public will be trivial.

Clearance is now a mature concept being used for the management of large amounts of radioactive materials (including metals, building rubble, cables and plastics) and disused buildings associated with a controlled nuclear activity. There are, however, differences in the ways in which clearance is dealt with in the regulatory frameworks of various countries and the ways in which clearance has been implemented in diverse decommissioning projects.

This report provides up-to-date information on an array of national approaches to clearance. It should be of particular help to those planning the implementation of a clearance procedure, such as that for decommissioning a nuclear facility.
