Radiologic Technology Board Review
1. Therapeutic radiology equipment operates at energy
levels than diagnostic.: higher
2. Fleming's hand rules are based on flow.: current
3. The exposure switch on an x-ray machine is intended to:: initiate
exposure
4. A rectifier converts energies that are to .: AC to DC
5. A motor converts energy to energy.:
electrical, mechanical
6. The resistance in a wire decreases as its:: diameter increases
7. If the total resistance in a circuit is 9 ohms and the total voltage is 3
volts, the current is:: 1/3
1/3
, 8. If there are 5 turns in the primary coil and 10 in the secondary coil,
which two of the following would be true?: * it is a step-up
* the volts would increase
9. Automatic exposure control (AEC) technology determines:: exposure time
10.When compared to single-phase electrical current, three-phase power::
* permits shorter exposures
* produces 360 pulses per second
* produces less voltage ripple
11.The periodic table is based upon:: atomic number
12.Photon wavelength is:: inversely proportional to photon frequency
13.The maximum number of electrons found in any energy level (shell) at
any point in time is:: two times the given shell squared
14.The sum of protons and neutrons in a nucleus is called the:: mass
2/3
