Abstract: 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.

Abstract: A storage phosphor material comprising a storage phosphor of the kind in which electrons excited by incident ionizing radiation may be trapped in stable trap sites and subsequently released by stimulation such as photostimulation, wherein the phosphor is contained within a host matrix which comprises a sol-gel glass in which the storage phosphor is incorporated as a dopant.
