WebX-rays, also known as X-radiation, refers to electromagnetic radiation (no rest mass, no charge) of high energies. X-rays are high-energy photons with short wavelengths and thus very high frequency. The radiation frequency is key parameter of all photons, because it determines the energy of a photon. http://www.radtechonduty.com/2024/07/characteristic-of-xray-primary-xray-and.html income for medicaid family of 3
