Polycarbonates and Copolycarbonates as Dosemeters
The obstacle of inconsistent properties of CR-39 polycarbonate as etched track dosemeters has been overcome with the multi-stage thermal polymerisation of purified monomer. Excellent linear correlation of track density with neutron dosage was observed after chemical and/or electrochemical etching. Excellent tracks were also obtained for radon exposure. Copolymers of CR-39 with methyl acrylamido glycolate methyl ether, MAGME, have been explored as a means of improving track etching and better simulating human tissue.
