Recently, polymeric nanocomposites have been used as real-time detectors and dosimeters of gamma radiation. In this experimental work, multi-wall carbon nanotubes (MWCNT) were dispersed in polystyrene (PS) martix with a weight percentage of 0.05 wt%. SEM images confirmed the appropriate and uniform distribution of carbon nanotubes in the polymer matrix. The dark current and photocurrent of the nanocomposite were measured under gamma irradiation of 60Co source using an electrometer in the voltage region of 1-500 V, and the dose rate range of 40-134 mGy/min. The results showed that this dosimeter in the array form of 2 pieces in comparison with the 1 and 3 pieces show a better response in the mentioned dose-rate and voltage ranges. Thus, this nanocomposite can be used as an active dosimeter in the diagnostic and therapeutic level.
