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.
