AB  - PURPOSE: This study aimed at proving the ability of bismuth-nanoparticle (Bi-np) 
      in dose enhancement effect (DEE) using the polymer gel dosimeter. Two different 
      polymer gels, namely poly acrylamide gelatin tetrakis hydroxymethyl phosphonium 
      chloride (PAGAT) and N-isopropylacrylamide (NIPAM) gels were chosen for this 
      study. MATERIALS AND METHODS: The gels were doped with Bi-np particle with 
      various concentrations of 0.5 mM, 1 mM, and 2.5 mM and were then irradiated with 
      a CO-60 gamma radiation source of energy 1.25 MeV. Gel samples were analyzed by 
      spectrophotometer. The dose enhancement factor (DEF) was calculated for both gels 
      for all concentrations of Bi-np particle. RESULTS: The higher DEF for PAGAT and 
      NIPAM was calculated as 1.3415 and 1.1823, respectively, for 0.5 mM concentration 
      of Bi-np. CONCLUSION: From our results, we infer that 0.5 mM is the optimal 
      concentration in polymer gel to obtain good DEEs in the energy range of 1.25 MeV.
