Radiation is neither dangerous nor harmful to an unborn baby when the mother's stomach is well covered during pregnancy and X-rays are taken. The child was probably well protected by the lead plate covered by the pelvic region during the X-ray. In general, radiation obtained from a single X-ray is so low that it cannot make an early pregnancy harmful. Nevertheless, telling the doctor about the X-ray and pregnancy is always the best choice. They might wish to examine the pregnancy more often to make sure that it is developing properly.
