Comparison of Model Predictions for DL Half-Values and Number of Snips per Gy for Average Soma Survival Rates

	Model	DL half-values (Gy)		No. of snips/Gy
	Model	Single	Population	No. of snips/Gy
⁴⁸Ti (129 keV/μm)	SDM	2.663	0.976	14.51
	RND1	3.031	1.088	15.37
	RND2	2.707	1.412	17.83
¹⁶O (16.3 keV/μm)	SDM	2.629	0.930	15.8
	RND1	2.558	0.925	16.03
	RND2	2.265	1.142	18.68
0.4 keV/μm	RND1	2.927	1.057	15.57
0.4 keV/μm	RND2	2.603	1.364	18.12

Notes. The half-values in Gy are calculated for DL reduction per Gy of absorbed dose in the SDM, RDM1 and RDM2 models for parameters (D_TH,S, D_TH,D, DL_TH) set at (5 Gy, 600 Gy, 0.5). The LET of 0.4 keV/μm is representative of d rays and is used in the simulations of the RND1 and RND2 models. The number of snips per Gy shown in the last column is identical in the single and population analysis.
