Comparison of Model Predictions for Absorbed Doses for DL Half-Values Number of Snips per Gy Assuming High Soma Survival Rates

	Model	DL half-values (Gy)		No. of snips/Gy
	Model	Single	Population	No. of snips/Gy
⁴⁸Ti (129 keV/μm)	SDM	1.616	0.660	10.03
	RND1	1.801	0.756	9.17
	RND2	1.630	0.723	12.33
¹⁶O (16.3 keV/μm)	SDM	1.754	0.744	9.61
	RND1	1.718	0.720	10.0
	RND2	1.554	0.687	13.53
0.4 keV/μm	RND1	1.691	0.699	10.17
0.4 keV/μm	RND2	1.537	0.670	13.74

Notes. The half-values in Gy are calculated for DL reduction per Gy of absorbed dose in the SDM, RDM1 and RDM2 models using (D_TH,S, D_TH,D and DL_TH) set at (>1,000 Gy, 300 Gy, 0.5). The LET of 0.4 keV/μm is representative of δ rays and is used in the simulations performed in the RND1 and RND2 models. The number of snips per Gy shown in the last column is identical in the single and population analysis.
