Digital X-ray: Frequently Asked Questions

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. 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.
