[en] In the present work an innovating methodology is proposed to estimate the absorbed dose received by individuals irradiated with neutrons. The method combines measurements of ²⁴Na and ³²P activated in the human body. A detailed study of papers published in the literature reporting neutron measurements in different facilities was combined to the results obtained after irradiation of an anthropomorphic phantom in the Argonauta reactor at the Institute de Engenharia Nuclear (IEN), Rio de Janeiro, Brazil. The results demonstrate that it is possible to correlate the measurements of those two activated elements (²⁴Na e ³²P) in order to assess the absorbed dose due to neutrons. A methodology was developed in which it is not necessary to know the neutron spectra inciding over the irradiated person or to use models to treat results of ³²P measurements, as occurs with other theoretical and experimental proposed methods.
