Description of X-rays:
X-rays are electromagnetic radiation that penetrates structures within a body and creates images of the structures on photographic film or a fluorescent screen. X-rays are a form of radiation that is very similar to light rays except X-rays are more energetic and are not visible to the human eye. The travel at the speed of light. X-rays can pass through air and soft tissue easily but will be stopped when it encounters more dense materials, such as a tumor, bone, or metal fragment.
Soft X-rays have comparatively high frequencies — about 3 × 1016 cycles per second, or hertz, to about 1018 Hz — and relatively short wavelengths — about 10 nano-meters (nm), or 4 × 10−7 inches, to about 100 picometers (pm), or 4 × 10−8 inches. (A nano-meter is one-billionth of a meter; a picometer is one-trillionth of a meter.) Hard X-rays have frequencies of about 1018 Hz to higher than 1020 Hz and wavelengths of about 100 pm (4 × 10−9 inches) to about 1 pm (4 × 10−11 inches).

Health Impacts
Negative - Many people believe that to much radiation from X-Rays can lead to cancer, which isn't necessarily untrue, though it has to be high dosages.
Positive - X-Rays can be helpful when Doctors need to detect an injury or disease. X-rays are also painless, and don't require any recovery time.
