but the concern with pregnant women flying isnt whether or not their greenie fits. its radiation to the unborn child. See with most people radiation isnt good, but because the body is self-repairing in normal amounts its no more harmful than anything else in this world. However, in a developing babies whos cells are reproducing at insane rates comparitively speaking (cellular reproduction is when cells are most vulnerable to the ionizing effects of radiation)....so unless that flight suit is made out of lead you havent mitigated any risk to the child
