as low as reasonably achievable
background equivalent radiation time
biologic damage
damage in living tissue
biologic effects
damage to living tissue of animals and humans exposed to radiation
cellular damage
injury on the cellular level resulting from sufficient exposure to ionizing radiaiton at the molecular level.
diagnostic efficiacy
the degree to which the diagnostic study accurately reveals the presence or absence of disease in the patient
effective dose (E)
a quantity that is used for radiation protection purposes to provide a measure of the overall risk of exposure to ionizing radiation. Effective dose takes into account the dose for all types of ionizing radiation to organs or tissues in the human body being irradiated and the overall harm, or weighting factor, of those biologic components for developing a radiation-induced cancer (or for the reproductive organs, the risk of genetic damage).
electromagnetic spectrum
the complete range of frequencies and energies of electromagnetic radiation
electromagnetic wave
electric and magnetic fields that fluctuate rapidly as they travel through space, including radio waves, microwaves, visible light, and x-rays.
equivalent dose (HT)
A quantity that attempts to take into account the variation in biologic harm that is produced by different types of radiation by considering the type and energy of the radiation. Equivalent dose enables the calculation of the effective (E) dose.
genetic damage
radiation damage to generations yet unborn
the conversion of atoms to ions
ionizing radiation
radiation that produces positively & negatively charged particles (ions) when passing through matter
manmade, or artificial, radiation
ionizing radiaiton created by humans for various uses, including nuclear fuel for generation of power, consumer products containing radioactive material, and medical radiation
natural background radiation
ionizing radiaiton from environmental sources, including radioactive materials int he earth, cosmic radiation from space, and radionuclides deposited in the human body
