Abstract:
We have proposed a novel polymer gel dosimeter containing of 2-hydroxyethyl methacrylate (HEMA), nonaethylene glycol dimethacrylate (9G), and tetrakis (hydroxymethyl) phosphonium chloride (THPC) with radiation-crosslinked hydroxypropyl cellulose (HPC) gel sheet. The transparent sheet-type dosimeters became white and cloudy by irradiation with gamma-rays and heavy ions such as He ions (150 MeV/u), C ions (290 MeV/u), Fe ions (500 MeV/u). The cloudiness increased with increasing dose. The cloudiness distribution with the sheet-type dosimeter was obtained by using a flatbed scanner to evaluate the dose distribution. Recently, we prepared a three-dimensional dosimeter by putting the gel sheets on top of another in the glass vessel. Three-dimensional dose distribution of the dosimeter irradiated with C ions was evaluated by the reconstruction of the data of each layer.
