  • Abstract
    Radiation damage in undoped CsI and CsI(Tl) crystals using 60 Co gamma radiation for doses up to ~4.2×106 has been studied. 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(Tl)
