## Abstract Color centers in undoped YAP crystals induced by gammaβirradiation were investigated by means of additional absorption spectra and thermal treatments. Color centers related to the 265 and 311 nm absorption bands were caused by Fe impurity ions and the charge state recharge of the Fe^3+^
