RADIOLOGIC SCIENCE FINAL REVIEW TEST QUESTIONS WITH COMPLETE SOLUTIONS

Melting of the anode commonly occurs - when the stator fails and the rotor ceases to turn All of the following are part of the cathode assembly except - stator The orderly arrangement of elements in the periodic table is based upon - atomic number The sum of protons and neutrons in a nucleus is called the - mass number Which of the following would affect the production of a thermionic cloud - ALL of the above (filament diameter, filament temperature, filament length) All of the following are true of electromagnetic energies except . - The relationship between frequency and wavelength is direct and proportional To increase the thermal loading capacity of the anode, x-ray tube manufacturers - bond graphite to the back of the anode The energy of a bremsstrahlung photon is . - the difference between the entering and exiting kinetic energies of the incoming electron At the end of the characteristic cascade, the ________ shell is missing an electron - outermost The unit of mass is the - Kg Which of the following is not a basic characteristic of the wave equation . - energy The function of the cathode is to produce . - thermionic cloud Tungsten is the material of choice for the source of x-ray photons primarily because of its - high atomic number The energy of a characteristic photon is - the difference between the binding energy of the outer and inner shells between which the electron dropped The maximum number of electrons found in any energy level (shell) at any point in time is calculated by the formula . - 2n^2 X-rays are characterized as . - both b and c (electromagnetic waves of short wavelength, electromagnetic waves with high frequencies A filament may break due to . - vaporization As the actual focal spot size increases, the effective focal spot size . - increases Bremsstrahlung interactions may occur only when the incident electron interacts with - the force field around the nucleus
