Comparative analysis of the X-ray dosimetric characteristics of CdGa₂S₄ and
CdGa₂S₄<Cu> single crystals demonstrates that after copper-doping the persistence of the
crystal characteristics completely disappears. The current-dose characteristics Ir ~ E
tend to linearity (α = 1) at low dose rates of X-rays. At high dose rates, α tends to 0.5,
which testifies to the mechanism of quadratic recombination of charge carriers generated
by X-rays in CdGa₂S₄<Cu>.
