Magnetic Resonance Imaging Study of New PAGAT Polymer Gel Dosimeter

    Graphical Abstract
    • Abstract
  • A new type of PAGAT polymer gel dosimeter, containing acrylamide, gelatin,-N, N′-methylene-bisacrylamide (BIS), tetrakis (hydroxymethyl) phosphonium chloride (THPC) and formaldehyde, was prepared under normal atmospheric conditions. The results show that its transverse relaxation ratio increases with the absorbed dose and its minimum detection limit is given. The dosimeter has good uniformity of one batch (better than 3.2%) and negligible dose-rate dependence in the range of 0.05-1.00 Gy/s. Using the gel dosimeter, the dose distribution of a heterogeneous interface was obtained and the dose enhancement effect was analyzed.
