The single crystals were grown from preliminarily synthesized polycrystals by the method of chemical transport reactions in a closed volume with iodine used as a carrier. The influence of doping CdIn2S4 single crystals by gold (3 mol %) on their X-ray dosimetric parameters is studied. It is found that the X-ray sensitivity coefficients of crystals increase 6–8 times compared with undoped CdIn2S4 at effective radiation hardness  keV and dose rate  R/min. Moreover, the persistence of the crystal characteristics completely disappears and the supple voltage of a roentgen detector decreases threefold. The dependence of the steady X-ray-induced current in on the X-ray dose is described by linear law. The studied crystals have a rather high room-temperature X-ray sensitivity ( (A·min)/(R·V)) and are attractive as materials for X-ray detectors.
