Re: Prenatal Exposure

I hope this will be of help. I have personally found the UK's National 
Radiological Protection Board's 'Documents of the NRPB' Volume 4 No. 4 
1993 which includes the 'Board Statement on Diagnostic Medical 
Exposures to Ionising Radiation During Pregnancy' very useful when 
answering questions about risks from radiation exposure of a conceptus 
during pregnacy.
