Electrical conductivity dosimetric characteristics of gamma-irradiated food salt


The electric conductivity characteristics of sodium chloride solution , have been studied in the present work considering its usage as a high dose dosimeter “accidental dosimeter” in the case of a nuclear fallout . Aqueous solution of gamma-irradiated food salt was investigated for dosimetric purpose using the electrical conductivity method. It was found that the solution containing [10-100]%(w/w) of food salt the most sensitive to radiation . The variation of electrical conductivity of all the solution was found to increase linearly with absorbed dose in the range (3-120) kGy. Reproducibility ,radiation dose response ,dose rate, and stability can have been studied.The results of this preliminary study show that food salt solution may be applied to a simple electrical conductivity detector for dose measurement in the dose range (3 – 120)kGy .
