Development and Characterization of a Portable Fibre Optic Dosimeter
A portable fibre optic dosimeter has been developed that uses transparent fluroperovskite dosimeters at the end of a multimode polymer fibre. It uses two stimulation sources that take advantage of the bimodal trap distribution so that the dose rate and cumulative dose can be monitored. Photoluminescence (PL), optically stimulated luminescence (OSL) and radioluminescence (RL) measurements were made on nearly tissue equivalent NaMgF3:Eu2+, NaMgF3:Mn2+, and high sensitivity RbMgF3:Eu2+ and CsCdF3:Mn2+. Initial dose rate and dose measurements were made using our fibre dosimeter during and after exposure to 60 keV gamma rays.
