Dose limits set by: {Ans: NRCP}Rectification {Ans: the process by which alternating current is changed to pulsating direct curent}What factor determines the minimum reaction time? {Ans: It is determined by the length of time necessary for the AEC to respond to the radiation and for the generator to terminate the exposure}How many pulses are there per Hz for 1phase and 3 phase power? {Ans: single = 2 pulses three = 3 pulses}Fixed tabletop {Ans: do not permit tilting of the patient's head}pair production. {Ans: In a pair production interaction the energy of the x-ray photon is converted to matter in the form of two electrons. For this interaction to occur, a very-high-energy photon with an energy of at least 1.02 MeV is required. --> This energy is used to create a pair of electrons, one with a negative charge, a negatron, and the other with a positive charge, a positron. => Pair production requires a minimum incident photon energy of 1.02 MeV but doesn't become a significant interaction until approximately 10 MeV. does not occur in the imaging range.}What is the difference between an ionization chamber and a phototimer? {Ans: Ionization chambers is
