Physics and Radiation Dosimetry. Introduction. â¢Charged particles have surrounding Coulomb field. â¢Always interact with electrons or nuclei of atoms in. matter. â¢In each interaction typically only a small amount of. particleâs kinetic energy is lost (âcontinuous slowing-. down approximationâ â CSDA) â¢Typically undergo very large number of interactions,
