Neutron Dose Rate. Neutron dose rate in the water phantom (beam profile of 9 × 9 cm2 ): comparison of the voxelised (green triangle, integration over 8 central voxels) and the solid box geometry (blue circle = with walls, pink circle = without walls) calculated with GEANT4 (error bars provide one standard deviation as calculated in GEANT4), together with the measurement of Kampfer [30] (red square).
