1) You may come back to this page and read the article as many times as you would like. 2) When you are ready to proceed to the test, just click on the "Take the test" link at the bottom of the page. 3) If you are not registered or logged in, you will be prompted to do so at that time. 4) Once you are registered you may take the test. 5) When you have passed the test you will be instructed on how to pay for your CEU in order to receive your certificate of completion. 6) If you choose not to pay at this time, you can log back in anytime in the future (your data is saved for your convenience), though
you will not receive the ARRT CEU numbers until after you pay.

-----------------
Discuss the three fundamental components of the atom and their relationship to ionizing radiation production.
Discuss the arrangement of the fundamental particles of an atom and how they contribute to the stability or instability of an atom's nucleus.
Discuss the factors that contribute to the emission of particulate and electromagnetic radiation from the nucleus of a nuclide.
List and discuss the types of nuclear transformations that are important to nuclear medicine.
Discuss the production of positron emission and the subsequent interactions positrons will undergo.
Discuss the production of electromagnetic radiation in x-ray tubes and list some of the commonly used x-ray equipment that produces it.
Discuss the production mechanisms of bremsstrahlung and characteristic electromagnetic radiations produced in x-ray tubes.
Compare the energy and penetrability of particulate and electromagnetic radiation as functions of their deionization potentials.
State the relationship between a photon's wavelength and frequency, energy and frequency, and energy and wavelength.
Discuss the production of gamma radiation outside the nucleus of an atom by mechanisms that involve the positron annihilation reaction.
Explain the mechanisms of K-shell electron capture, Auger electron production, characteristic radiation production.
