Is the radiation from X-rays dangerous?
X-rays are a type of photoelectric radiation that are short-wave rays that can more easily travel through molecules than longer-wave rays such as lightwaves. These rays can travel through soft tissues like those found in the human body and be able to produce an image based on the density of the matter of which it passes, hence the ability to see outlines of bones vs. various body tissues. In the medical field X-rays are used in many kinds of scan diagnostics, an example being a CT scan you might get at the hospital. Though in general you want to avoid exposure to radiation of all types but truth is that every day the human body is exposed to radiation on a constant basis, even occurring naturally. Fortunately, a dental x-ray is a minimal risk to radiation exposure the general public since there is less radiation in an x-ray than on an sitting on an airplane or heating up your food in the microwave. The benefits of getting a dental X-ray do outweigh the risks of radiation exposure.
