Abstract : Throughout the years, detection of fast neutrons has been a field of intensive study to improve the current methods of neutron dosimetry. This study proposes a new approach to measure neutron dose using a water-based chemical dosimeter. The dosimeter method is based on the radiation induced reduction of the hexavalent Cr (VI) to the trivalent Cr (III). Neutron absorbance material (Gd-157 and B-10) was added with different concentrations to increase the neutron interaction with the dosimeter. A Monte Carlo simulation toolkit was used to carry out the dose calculation. Cf-252 was used as a fast neutron source while a monoenergetic beam with 0.025 eV energy was used as a thermal neutron source. The results showed that 1 mol/dm3 of Gadolinium gave the best outcome while surrounding the dosimeter with 1 cm Gadolinium sheets. The dosimeter was giving acceptable readings when using fast and thermal neutrons. Future studies need to be carried out to run an experimental trial in the laboratory to verify if the simulations and experimental results match.
