Abstract
A method for real-time RL and/or ROSL dose rate measuring in an environment exposed to a radiation source(s). The method comprises the steps of exposing a dosimeter to the environment for irradiation by the radiation source(s), the dosimeter comprising a phosphor-doped fluoroperovskite compound, sensing the RL or ROSL emitted light from the dosimeter during irradiation by the radiation source(s) and generating a representative light detection signal, and recording or generating a real-time measure of dose rate in the environment based on the light detection signal. A radiation dosimeter detection system comprising a phosphor-doped fluoroperovskite compound, the dosimeter coupled to a detector by an optical fiber. The detector comprises first and second optical stimulation sources that transmit light over the optical fiber to the dosimeter in first and second wavelength ranges. An optical detector senses light emitted from the dosimeter from which read-out dose information is generated.
