Photon and neutron kerma coefficients for polymer gel dosimeters

• Neutron and gamma ray kerma coefficients were calculated in 17 3D dosimeters.
• Curves of gamma-ray kermas showed slight dips at about 60 keV.
• Disagreement between neutron kermas for water and polymers has been observed.
• The obtained results could be useful for dose estimation in the studied dosimeters.

Neutron and gamma ray kerma coefficients were calculated for 17 3D dosimeters, for the neutron and gamma ray energy ranges extend from 2.53×10−8 to 29 MeV and from 1.0×10−3 to 20 MeV, respectively. The calculated kermas given here for discrete energies and the kerma coefficients are referred to as “point-wise data”. Curves of gamma ray kermas showed slight dips at about 60 keV for most 3D dosimeters. Also, a noticeable departure between thermal and epithermal neutrons kerma sets for water and polymers has been observed. Finally, the obtained results could be useful for dose estimation in the studied 3D dosimeters.
