I believe it is because ultrasound uses sound waves whereas x-rays are a form of ionizing radiation. (Ionizing radiation is radiation with enough energy to remove electrons from their orbit around a nucleus.)
However, with today's advances in x-ray protection X-rays are not generally harmful unless in excessive amounts. Medical radiation (for the average individual) accounts for only 11% of the irradiation received over our lifetime. There are tons of consumer products (exit signs and skin lotions, for example) that expose us to radiation. Not to mention the sun...
Anyway, my point is that ultrasound is probably safer than X-rays. But it is also important to know that the type of diagnostic information produced by each is different and if your doctor recommends you get an xray, don't insult him by suggesting an ultrasound instead. :)

Ultrasound is less dangerous than x-rays because it does not use ionizing radiation. X-rays have the potential to cause damage to cells and DNA due to their high energy level, which can increase the risk of cancer. In contrast, ultrasound uses sound waves to create images, which are considered safe and do not pose any known risks to human health.

Are there any Ultrasound Technician Schools that can be completed in less than a year?
Yes, you can complete the ultrasound technician in less than one year. Many technical schools, Junior colleges and Universities offer ultrasound technician training classes for this fast track career that can land you a job in as little as one year.
What tornado is safer?
All tornados are dangerous, but there are stronger tornados than others. An F1 is less than an F2, so the lower the number, the safer( less dangerous) it is.

Why ultrasound rather than x ray is used to scan expectant mother?
Two reasons. Firstly, Safety. Fetus have a higher rate of cellular division than the average human being. A damaged gene while still developing can cause birth defects. Secondly, X-rays really only give an idea of bone structure and generally aren't live. It X-rays don't give as clear an indication on lung and heart development.
