Abstract
The CBRN Research and Technology Initiative funded project CRTI-02-0045RD to produce a prototype portable optically stimulated luminescence reader. That is, the project aimed to design, construct, and test a portable detector for measuring the stored radiation-induced signature in common building materials using the principle of optically stimulated luminescence. As such, a detailed characterization of many common building materials was also required. This prototype detector was successfully constructed and was field tested both at DRDC Ottawa and during CRTI Exercise MARITIME RESPONSE in Slemon Park, Prince Edward Island. The detector has always performed well, demonstrating a capability that heretofore has not existed in a portable device. The system has demonstrated the ability to detect past radiation exposures to materials including cement, concrete, drywall and ceramic tile, to name a few. The project team is currently pursuing the patenting and commercialization of this technology, and has received interest from outside the intended end-use community.
