Abstract
Colorations induced by Co-60 gamma-irradiation have been studied in si x 2.54 cm thick CsI(Tl) samples cut from three crystal boules grown in an experiment on the control of impurities. The growth of a ''sextet' ' structure of bands on the high-energy side of the F-band was observe d in all the samples as doses of gamma-rays were increased. It is spec ulated that the sextet bands may be related to the excited states of t he F centre. It is found that high concentrations of thallium in CsI(T I) always reduce tolerance to radiation.
