Abstract

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.

Keywords: Agar; And tetrakis (hydroxymethyl) phosphonium chloride (MAGAT); Dose distribution; Gelatin; Methacrylic acid; Polymer gel dosimeter; Radiotherapy.
