Susceptibility to radiation of rare‐earth elements and transition metals in Y 3 Al 5 O 12 , YAlO 3 , LiNbO 3 , SrGdGa 3 O 7 single crystals was investigated. Additional absorption bands after g‐irradiation with doses 10 3 ‐10 7 Gy and protons with fluencies of 10 13 ‐10 16 cm ‐2 were found. A decrease in additional absorption with increasing Pr 3+ , Dy 3+ and Cu 2+ and with decreasing Nd 3+ and Fe 3+ dopant concentration was observed. Dopants like Ce 3+ and Cr 3+ show a relatively complex behavior. This behavior strongly depend on the type of radiation and its dose.
