Optically stimulated luminescence in forensics

Appl Radiat Isot. 2005 Nov-Dec;63(5-6):689-95. doi: 10.1016/j.apradiso.2005.05.019. Epub 2005 Jul 20.

Abstract

Tracking the former location of a radioactive source represents an attractive attribute in today's society, where the threat of a radiological dispersal device (RDD) is considered high. Development of a novel, retrospective detection technique based on optically stimulated luminescence is underway. This will allow confirmation of the former location of a radioactive source. Materials near the source's former location may be probed for information on accumulated dose by taking advantage of radiation-induced charge trapping that occurs in many common materials. The prototype detector design and analysis techniques are described.
