A self-consistent FLUKA algorithm for studying the response of passive dosimeters based on CR-39 track detectors in fast neutron fields

Characterization of a novel passive personal fast neutron dosimeter based on a CR-39 track detector in monochromatic neutron fields via Monte Carlo simulations and experiments

“…Finally, the morphological analysis of the CR-39s leading to the calculation was performed through the Politrack ® system [8], [16] and the experimental of the irradiated CR-39s values were obtained by subtracting the proper average background signal (depending on the CR-39 type) from the (gross) doses returned by the Politrack ® . On the other hand, the simulated values were computed through an algorithm for the FLUKA code developed by our team [17]; the algorithm works as follows: for any particle crossing the upper or lower surface of the sensitive volume which could contribute to the signal, the corresponding and impinging angle are scored and checked against the threshold value ( , according to experimental data) and the critical angle [18] value (drawn from [19]) that make a particle fit for producing a track and summing up the dose contributions linked to each track. The responses were then computed by Equation ( 2), for which the reference values were obtained from ICRP 74 [11].…”
