Radioactivity measurements using storage phosphor technology

The response of a storage photostimulable phosphor imager (SPP) system has been studied using alpha- and beta-particle point sources, large are sources and with environmental soil samples previously characterized for radionuclide content. Alpha radiation can be easily differentiated from other radiations. Furthermore, for thin sources, alpha-particle emitting radionuclides can be differentiated from each other. A number of other response characteristics of the system are also described.
