In the previous studies, a new type of gamma radiation dosimeter based on polymer/carbon nanostructures nanocomposite has been presented by the authors and also the dosimetric properties for this type of dosimeter have been investigated. In this experimental work, the electrical resistance of 0.28wt% Polystyrene/Multi-Walled Carbon Nanotube (PS/MWCNT) nanocomposite was measured at the temperature range of 25-75 °C. The work of a calorimeter is based on increasing the temperature of the sensitive volume due to irradiation. Results showed that with increasing the temperature, the electrical resistance of the nanocomposite was increased linearly and due to calorimetric relationships could be used as a calorimeter in the radiation processing region to measure the absorbed dose up to about 50 kGy.
