2015 Med Phys I Lecture 4.1a PreTest Question Title * 1. Name: Question Title * 2. Which of the following is an issue when we measure radiation dose in the clinic? Dose is only defined for x-rays and gamma rays. Dosimeters are only available at standardization laboratories. We calibrate our measuring instruments at one energy, but measure dose at a different energy. We cannot measure dose more precisely than 5%. Question Title * 3. Exposure is defined as Charge generated per unit mass Energy absorbed Energy absorbed per unit mass Number of Roentgens Question Title * 4. Which of the following looks at the amount of energy going from a photon to an electron at the instance of the photon interaction? Energy imparted Energy transferred Net energy imparted Net energy transferred Question Title * 5. Which of the following looks only at the energy received by the electron from the incident photon and deposited via collisional processes? Energy imparted Energy transferred Net energy imparted Net energy transferred Question Title * 6. Which of the following looks only at the energy received by the electron from the incident photon and deposited via collisional processes inside the volume of interest? Energy imparted Energy transferred Net energy imparted Net energy transferred Question Title * 7. Are there any issues that are not clear to you at this time? Done
