Mission type, duration (days)	E/Sv	REIC [%]		RADS [%]
		Males	Females	Males	Females
Lunar, 180	0.17	0.59 (0.44; 0.75)	0.88 (0.72; 1.07)	0.67 (0.51; 0.85)	0.94 (0.77; 1.14)
Mars swing-by, 600	1.03	3.20 (2.41; 4.10)	4.79 (3.89; 5.82)	4.00 (3.05; 5.11)	5.59 (4.57; 6.75)

It is assumed here that the effective dose, E in Sv is equal to the colon and RBM organ dose in Gy, and that the colon organ dose is equal to the RBM dose in Gy. Note: the very large uncertainties in the survival curve from e.g., the radiation dependant acute mortality in the survival curves above 2 Gy, are not included in the results for REIC
