We have studied the X-ray induced conductivity of an iron-doped CdIn2S4 crystal grown by chemical vapor transport. The results demonstrate that doping with 3 mol % Fe increases the X-ray induced conductivity coefficient of CdIn2S4 by a factor of 2–8 relative to CdIn2S4 at effective X-ray hardnesses in the range 25–50 keV and dose rates E = 0.75–78.05 R/min. The photocurrent-dose curves of the CdIn2S4〈Fe〉 crystal have almost no time lag, in contrast to those of CdIn2S4. The steady-state X-ray induced current through CdIn2S4〈Fe〉 is a power law function of dose rate: I X ∼ E α with 1 ≤ α ≤ 2.
