title: MULTI-PARAMETER INTERPOLATION OF BETA RADIATION DOSE RATES USING RADIAL BASIS FUNCTIONS.
abstract: In this study, the interpolation problem for a set of Monte Carlo simulations of dose rate per activity of beta-emitting radionuclides is considered. The simulations were carried out for various conditions: for circular areal sources of different diameters and radionuclides, and for various distances from the source. Calculations were done for both operational quantities as well as organ doses: Hp(0.07), Hp(3), Hp(10), Hskinand HlensInterpolation is needed for practical applications because it is often necessary to evaluate the dose quantities at parameter values that do not correspond exactly to the ones that were used for the simulation. To solve this problem, the method of radial basis function thin-plate spline interpolation is used. The method used for the interpolation and a software application called BetaDosim, which allows users to get the interpolated values, are described. BetaDosim is freely available.
