Table 4. Mutations at minisatellite loci in relation to parental exposure.

	Controls (<0.01 Gy)	Exposeda (≥0.01 Gy)
Number of children examined	58	61
Minisatellite loci tested	1403	496
Mutations detected	39	13
Mutation rate/loci/generation	2.8%	2.6%

Data are from Kodaira et al. (2010). Note that the irradiation level for the exposed parents is quite high.

^aMean parental gonadal dose = 1.47 Gy.
