Design and characteristics of an agar additive polymer gel dosimeter

Herein, we investigate the use of agar and gelatin in a polymer gel dosimeter. The polymer gel is enclosed in a vinyl film to obtain a dosimeter of arbitrary shape and maintain the shape at room temperature. The resulting polymer gel dosimeter could preserve its shape across a wide temperature range...

Summary:Herein, we investigate the use of agar and gelatin in a polymer gel dosimeter. The polymer gel is enclosed in a vinyl film to obtain a dosimeter of arbitrary shape and maintain the shape at room temperature. The resulting polymer gel dosimeter could preserve its shape across a wide temperature range. Excluding the surface region, the obtained dose distribution was within 3% of that determined in an ionization chamber. •Presented gel dosimeter was improved functionally by using ager and vinyl film.•The resulting MAGT-A dosimeter maintained its shape across a wide temperature range.•Dose distribution agreed within 3% compared to the ionization chamber.
