Abstract
Alpha track detectors (LANTRAK) have been used to map highly localised and inhomogeneous alpha emitter contamination on concrete, lead brick , metal, and vinyl floor surfaces. These detectors are easy to use, de monstrate good alpha sensitivity and high immunity to beta and gamma r adiations, and can be deployed in hard-to-access locations. Conversion efficiencies were measured ranging from 40% to 73% for radionuclides of interest. Illustrative examples of contamination mapping on a lead brick, tile floor, and a narrow ledge are discussed.
