Ionizing Radiation - radiation that is able to remove electrons from an atom through ionization Somatic effects - refers to the effects of radiation to the body being irradiated Genetic Effects - refers to effects of radiation to a germ cell's genetic code; effects the next generation Primary radiation - radiation exiting the x-ray tube Remnant radiation (or Exit Radiation) - x-rays the leave the patient and strike the image receptor

GSD (Genetically Significant Dose) - average annual gonadal dose of radiation to individuals of childbearing age; addresses the relationship of gonadal doses to individuals versus an entire population and the overall effects Linear Energy Transfer (LET) - amount of energy deposited by radiation per unit length of tissue Relative biologic effectiveness (RBE) - ability to produce biologic damage; varies with the LET
