	Kidneys	Liver	Lungs	Spleen	Reference
Cumulated activity (Ã) (kBq·s)	161544	313027	217091	49087	Lundh et al. [22]
Energy per decay (n _i × E _i) (keV)	190	190	190	190	MIRD [21]
Absorbed fraction (ϕ _i)	0.919	0.954	0.85	0.854	Flynn et al. [20]
Mass (g)	0.34	1.2	0.15	0.079
D (13 kBq) (mGy)	0.17	0.10	0.49	0.21
D (130 kBq) (mGy)	1.7	0.98	4.9	2.1
D (260 kBq) (mGy)	3.5	2.0	9.7	4.2

Values used for the absorbed dose calculation, Ã, n _i × E _i , and ϕ _i, are given with references, together with the mass of the organs. The estimated absorbed doses, D, delivered to the different tissues from 13, 130, and 260 kBq ¹³¹I are shown.
