Panel A: Total neuron death caused by soma death (soma) and dendritic snipping (dendrite) for absorbed dose, DF = 0.5 Gy by 16O (600 MeV/n) irradiation using model parameters, DTH,D = 250 Gy and DLTH = 0.5. Equilibrium value of total neuron death at large DTH,S (>10 Gy) leads to an asymptote to 0.20. Panel B: Total dendritic length of a single neuron is independent of DTH,S and mean value is DL = 0.74. For the DL value for normalized population of neurons, mean value reaches 0.59 when soma death is negligible.
