Abstract
‎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 0.16‎, ‎0.24‎, ‎and 0.32 mM have been prepared and irradiated with gamma rays between 100 to 1000 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 100 to 1000 Gy dosimetry range and the optimal concentration must be found to achieve a stable sample in about 3 weeks periods‎. ‎Also‎, ‎samples that are in a darker environment are more stable than samples that are in a lighter environment‎.

Highlights

• Chromium Nitrate solutions with different concentrations have been prepared.
• Irradiation was performed with gamma rays.
• Dosimetery factors was invesitegitaed in the range of irradiation of agricultural products.
