Emergency dosimeter

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.

This paper reports on the synthesis and characterisation of Dy2 O3 -doped magnesium borate (MB) glasses containing different modifiers, lithium, calcium, and sodium oxides. Glasses composed of (70-z)B2 O3 -20Li2 O; CaO; Na2 O-10MgO-zDy2 O3 (where 0.05≤z≤0.7 mol%) were prepared using the melt-quenching method. X-ray diffraction (XRD) pattern of the as-quenched samples verified their amorphous character. Differential thermal analysis (DTA) confirmed excellent glass-forming ability and thermal stability in the range of 0.60-0.67 and 0.18- 0.82, respectively.
