. - In this paper we summarize our work aimed at producing via Monte Carlo (MC) simulations an updated database of Voxel S-Values (VSVs) for the radioisotope 90Y, widely used in nuclear medicine therapies. The usually neglected contribution due to Internal Bremsstrahlung accompanying beta-decay was included in the computation of the VSVs, increasing their accuracy with respect to pre-existing databases. An analytical model enabling to extend the VSVs calculation to any voxel size of interest was additionally developed, to overcome the limitation due to the finite number of sizes directly evaluable via MC.
