x-rays are electromagnetic waves of extremely short wavelength and high energy. The X-ray has penetrability, but the density and thickness of human tissues are different, when the X-ray penetrates different tissues of the human body, the X-ray is absorbed to different degrees, and different images can be obtained after imaging treatment; fluorescence is the light emitted by a substance after absorption of light or other electromagnetic radiation. In most cases, the emission wavelength is longer than the absorption wavelength and the energy is lower.
