AB  - The mass attenuation coefficient (MAC), effective atomic number (Z(eff)), 
      equivalent atomic number (Z(eq)), fast neutron removal cross-section (FNRCS), 
      energy absorption buildup factor (EABF), mass-energy absorption coefficient 
      (MenAC), relative kerma, and computed tomography (CT) numbers were calculated for 
      the alginates, bisphenol A-glycidyl methacrylate (Bis-GMA), chitin, hyaluronic 
      acid, polycaprolactone (PCL), polyether ether ketone (PEEK), polyethylene glycol 
      (PEG), polyglycolide (PGA), polylactic acid (PLA), poly lacto-co-glycolic acid 
      (PLGA), poly methyl methacrylate (PMMA), poly vinyl alcohol (PVA), 
      polyvinylpyrrolidone (PVP), triethylene glycol dimethacrylate (TEGDMA), and 
      urethane dimethacrylate (UDMA) polymers using the Phy-X/PSD and Py-MLBUF 
      software. The total stopping power (TSP) of electrons, protons, and alpha 
      particles was calculated for the selected polymers using the ESTAR, PSTAR, and 
      ASTAR programs. The effective atomic number for absorption and charged particle 
      (electron, proton, alpha, and carbon ion) interactions were estimated for the 
      selected polymers using Phy-X/ZeXTRa software. The FNRCS values of Bis-GMA, PCL, 
      PEG, PMMA, and PVP were similar to those of the human tissues. For the selected 
      polymers, the Z(eff) values for electron, proton, alpha, and carbon ion 
      interactions of PCL, PEG, PLGA, and PVA were similar to those of human tissues, 
      except for the cortical bone, across the entire energy range. These results are 
      expected to assist in selecting suitable polymers as tissue-equivalent materials 
      in the desired energy range for photon, neutron, and charged-particle 
      interactions. This study is expected to be useful for radiation therapy and 
      dosimetry.
