Answer the following statement(s) true (T) or false (F)
1. To produce x-rays there must be a source of electrons, a force to drive the electrons, and an object for the electrons to hit.
2. X-rays can be focused by a lens.
3. X-rays cause fluorescence of rare earth phosphors.
4. One percent of the x-ray photons that are attributed to image production are a direct result of bremsstrahlung and characteristic interactions.
5. Attenuation is the complete absorption of x-ray photons as they travel through matter.
1. TRUE X-rays are produced at the anode target by accelerated electrons formed by thermionic emission.
2. FALSE One of the properties of x-rays is that they cannot be focused by a lens.
3. TRUE X-rays can cause certain phosphor crystals to emit light.
4. TRUE 99% of the anode target interaction caused by the kinetic energy of the electron impact is converted to heat.
5. FALSE Attenuation is partial absorption resulting in a decrease of beam intensity.
