AbstractA 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 NaMgF 3:Eu 2+, NaMgF 3:Mn 2+, and high sensitivity RbMgF 3:Eu 2+ and CsCdF 3:Mn 2+. Initial dose rate and dose measurements were made using our fibre dosimeter during and after exposure to 60 keV gamma rays. © (2012) Trans Tech Publications, Switzerland.
