Abstract: | This work is devoted to the calculation of the concentration of radiation displacement defects (RDD) in bismuth germanate
and bismuth silicate crystals as a function of particle energy (electrons and neutrons). Energy dependencies of RDD concentrations
are discussed in comparison with results for other complex oxide crystals. The obtained results show that for the case of
electron irradiation the radiation hardness of BSO and BGO should be similar to other oxide crystals, but for neutrons is
drastically smaller. Additionally, for the neutron irradiation, the efficiency of the production of defects in the oxide sublattice
is drastically smaller than for other oxide crystals.
