Are X-Rays Completely Safe?
Doctors do a lot of x-rays on children. Is there a risk to that, or are x-rays completely safe? The answer, for chest, bone, and abdominal x-rays, is that they are very, very, very safe, but not totally risk-free. All of us are constantly exposed to radiation similar to x-rays. It comes primarily from naturally-occurring radioactive things around us, such as radon gas seeping up through the ground, or from outer space in the form of cosmic rays. People living at higher altitudes receive higher doses of such background radiation, amounting to about half again as much for someone living on the Colorado plateau compared with someone at sea level. To put things in perspective, the radiation dose in a single chest x-ray, on average, is similar to the background radiation most of us receive during a ten day time span living our normal lives.
