attenuation the reduction of radiation intensity due to scattering and absorption
radio waves the energy of a photon is directly proportion
x-ray are usually identified by their energy (or wavelength)
velocity electromagnetic radiation is constant
nucleus gamma rays are produced in the nucleus of the atom
