Values of β_F and η used for estimation of EAR (cancer incidence) due to mammography, MBI, BSGI, and PEM. Values were extracted from BEIR VII (Table 12-2).

Liver	1.0	−0.41	4.1
Lung	3.4	−0.41	5.2
Breast	9.4	−0.51	3.5 (attained age<50)
			1.1 (attained age>50)
Uterus	1.2	−0.41	2.8
Ovary	0.70	−0.41	2.8
Bladder	0.75	−0.41	6.0
