The effect of sunlight on Φ 2.54 × 2.54 cm2 CsI(Tl) crystal of Tl concentration 500 ppm has been studied. Long period of sunlightexposure can induce new defects and reduce the transparency of the crystal. The optical absorption spectra in the infrared region are mostly affected rather than in the visible region. After the exposure of sunlight the rate of optical bleaching and optical darkening effect on CsI(Tl) crystal is almost same.
