For the same 1 Gy dose of photons (reference X-ray field) and of the mixed neutron – photon field: experimental results on foci yields at 24 hours after exposure; range of predicted foci yields (from DSB clusters) in 2D, varying the slice thickness Δz (0.5; 1 μm) and the clustering radius r (0.5; 1 μm); range of predicted foci yields (from DSB clusters) in 3D, varying the clustering radius R (0.5; 1 μm).
