Abstract:
A new dosimetry system based on di-sodium tartrate was investigated. Unirradiated and irradiated sample spectra were recorded and described. Effects of the change in microwave power and modulation amplitude values on the signal amplitude and the line width of the two peaks were plotted. Response to the Cs-137 gamma radiation was studied in two ranges: high-dose range (2409.66-41.97) Gy and low-dose range (41.97-1.40) Gy. The first peak of di-sodium tartrate is found to be 1.2 times more sensitive than that of alanine in the dose range (2409.66-41.97) Gy; moreover, in the dose range (41.97-1.40) Gy, it is found to be 1.3 times more than that of alanine. For the second peak of di-sodium tartrate, it is found to be less sensitive than that of alanine in the dose range (2409.66-41.97) Gy by a factor of 0.41, whereas in the dose range (41.97-1.40) Gy, it is found to be 0.44 times less than that of alanine The minimum detectable dose for di-sodium tartrate is about 0.05 Gy for the first peak and 1.4 Gy for the second peak.
