Yes: Yes, ultrasound is safer than x-rays. The energy source for ultrasound is sound waves which has been established as safe in limited procedure times during pregnancy. X-ray energy source is radiation which has been established to be detrimental in higher doses to developing in utero babies.

Yes: Sound wave energy from ultrasounds are considered to be safe during pregnancies, but radiation energy from x-rays have been found to be detrimental to the developing fetus.
Dr. Brian Enggano
Obstetrics and Gynecology 13 years experience
Yes: For pregnant women, ultrasounds are safer than x rays because sonograms use sound waves, which do not affect the baby. On the other hand, ct scans and x rays use radiation, which do have risks to the unborn child at very high levels. Discuss this with your doctor.

For adults as well there is no ionizing radiation which although very low can increase risk of certain cancers

Also, may be less sensitive, less specific, and just not usable if there is an air or gas interface or bone between probe and lesion. Transducer positioning can also vary. U/S very useful some indications, useless in others.

X-rays: contribute to a slight theoretical increased lifetime cancer risk. Diagnostic ultrasound has no known deleterious effects. All else being equal, then, to the best of our knowledge, US would be considered safer.
