Resumen:
Abstract. In-phantom measurements of physical dose distributions are very important for BNCT
planning validation. During exposure to thermal or epithermal neutrons, the absorbed dose in
tissue is released by the various components of secondary radiation. Therefore, it is necessary to
determine the spatial distributions of the absorbed dose, separating the various contributions due
to each different secondary radiation produced by neutrons in tissue, because they have dissimilar
biologic effect. The spatial trends of the different dose components and their relative
contributions in each position depend on the beam geometry and also on the size and shape of the
irradiated volume. It is therefore necessary to perform spatial determinations of each dose
contribution, both in tumor and in healthy tissue.
