A system for criticality incident detection is described. The system comprises a plurality of sensors at least partially comprised of storage phosphors. The sensors are distributed throughout the environment to be monitored. The sensors are coupled to a central detection system comprised of at least a luminescence detector and a processor. The luminescence detector measures the luminance of the sensors and provides that measurement to the processor. The processor then calculates the radiation level that the luminance measurement corresponds to. In other embodiments, monitoring units are installed in various portions of the environment being monitored. The monitoring units accept the sensors and are coupled to the central detection system so that the remote monitoring units can be interrogated from the central detection system.
A method of detecting radiation, the method comprising exposing a stimulable phosphor material to an environment, the environment potentially containing radiation, and further comprising stimulating the phosphor material to cause stimulated luminescence and detecting the stimulated luminescence arising from the stimulable phosphor and determining a function of the amount of radiation incident on the stimulable phosphor material from the detected stimulated luminescence, wherein stimulable phosphor material is provided in non-fixed positions during exposure to the environment.
A method of detecting radiation, the method comprising exposing a stimulable phosphor material to an environment, the environment potentially containing radiation, detecting luminescence arising from the stimulable phosphor and determining the amount of radiation incident on the stimulable phosphor material from the detected luminescence.
A radiation detector, the detector comprising a stimulable phosphor material, the detector further being adapted to cooperate with luminescence detector means processing means for determining the amount of radiation incident on the stimulable phosphor material from the luminescence detected and arising from the stimulable phosphor, wherein the stimulable phosphor material is provided in a light tight container and the detector is provided with different thicknesses of shielding for the stimulable phosphor.
