Three-dimensional measurements of absorbed dose by thermal neutrons in a tissue-equivalent phantom were performed utilising a thermal column of the fast research reactor TAPIRO, in Casaccia ENEA Centre, near Roma, Italy.The TAPIRO reactor is a highly enriched (93.5%) Uranium-235 fast neutron facility.In this experiment, we have utilised the thermal column. Here a proper structure made with graphite blocks was set up to thermalize neutrons.We have set up a technique to measure the 3-D distribution of absorbed dose in a phantom exposed in the thermal neutron flux. The technique is based on a chemical dosimeter (ferrous sulphate solution) incorporated in a tissue-equivalent gel (Agarose).
