Abstract
Optical properties of large size lead fluoride (PbF2) crystals of thre e different manufacturers and their degradation caused by Co-60 gamma- radiation have been investigated. Transmission losses have been system atically studied at absorbed energy doses between 0.1 and 7 kGy. Sever al radiation induced absorption bands have been observed. Optical blea ching with light of wavelengths greater than or similar to 365 nm has been found very effective to restore the original characteristics even after repeated irradiations. This observation together with the high density and the ultraviolet extended transmission make PbF2 an excelle nt choice for high rate and high resolution e.m. calorimetry.
