Effects of low dose prenatal irradiation in humans:  analysis of Chicago 
lying-in data and comparison with other studies,

Radiat Res 1974; 57: 508-544.

I imagine this is the study  of interest.

Follow up (prospective)  study on 1000 first born infants whose mothers 
were subjected to routine x-ray pelvimetry .    the program commenced in 1948.

estimated mean fetal dose  is given as 700 mrad.  Technical details are 
provided as an appendix.

The bottom line:  No conclusive evidence of a radiation effect was found.
