On the feasibility of polymer fibers with mineral filler as emergency dosimeters

The objective of this study is to examine the possibility of using the thermoluminescence (TL) of polymer fibers containing ground calcium carbonate (CaCO3 ) mineral fillers as emergency dosimeters. Calcite, consisting mostly of CaCO3 , is a TL material that exhibits two distinct TL peaks that can be exploited for dosimetry and is a naturally occurring mineral that is ubiquitously in use in everyday materials.
