“Are X-Rays harmful to my health?”
In tests that do use ionizing radiation, the dose is usually very small, and is often similar to what you would get from natural background radiation in everyday life. As an example, a dose for a typical X-ray procedure might be 30 – 1,000 mr. Despite extensive study of the effects of radiation, direct evidence does not show that these doses are harmful to humans. Medical x-rays have increased the ability to detect disease or injury early enough for the problem to be managed, treated or cured. X-ray energy has a small potential to harm living tissue. In diagnostic uses, only theoretical models suggest the possibility of cancer risks, but these models extrapolate results from higher exposures to these low levels, and no one is certain about whether or not any real risks are involved (Health Physics Society). It is worthwhile noting that depending upon the region of the world in which we live, we are exposed to varying amounts of radiation each year. For example if you live in Denver, Colorado, the annual dose would be approximately 600 millirads (mr) just from background radiation alone.
