OSTI ID:10117538
Radiation damage has been studied in undoped CsI and CsI(TI) crystals using {sup 60}Co gamma radiation for doses up to {approximately} 4.2 {times} 10{sup 6}. Samples from various manufacturers were measured ranging in size from 2.54 cm long cylinders to a 30 cm long block. Measurements were made on the change in optical transmission and scintillation light output as a function of dose. Although some samples showed a small change in transmission, a significant change in light output was observed for all samples. Recovery from damage was also studied as a function of time and exposure to UV light. A short lived phosphorescence was observed in undoped CsI, similar to the phosphorescence seen in CsI(TI).
