Investigation of the response of chromium nitrate solutions as a chemical dosimeter for agricultural applications

‎Irradiation of agricultural products is used to optimize properties and pest control and also increase the storage time of products‎. ‎The desired irradiation result is obtained when the required dose is given to the sample‎. ‎Dosimetry is a method for separating and classifying materials and equipment that is provided to the user to confirm the acceptance of irradiation and control the performance‎. ‎In this work‎, ‎Chromium Nitrate solutions with concentrations of ۰.۱۶‎, ‎۰.۲۴‎, ‎and ۰.۳۲ mM have been prepared and irradiated with gamma rays between ۱۰۰ to ۱۰۰۰ Gy‎. ‎The purpose of this study is to investigate the dosimetry of these samples in the range of irradiation of agricultural products‎. ‎Results show that the higher concentration sample is linear in about ۱۰۰ to ۱۰۰۰ Gy dosimetry range and the optimal concentration must be found to achieve a stable sample in about ۳ weeks periods‎. ‎Also‎, ‎samples that are in a darker environment are more stable than samples that are in a lighter environment‎.
