Radiology Chapter 5 Questions and Answers | Latest Version | 2024/2025 | Correct & Verified The purpose of collimation is to limit the size of the X-ray beam. True Higher kVp settings produce X-rays with greater energy and penetration. True Radiation exposure decreases as the distance from the source increases. True Scatter radiation has no effect on image quality. False Protective lead aprons are designed to absorb scatter radiation. True 2 Filtration helps remove high-energy X-rays from the beam. False A grid is used to reduce patient dose. False Increasing mAs increases the number of X-rays produced. True Reducing exposure time decreases motion blur in images. True ALARA is a principle that promotes minimizing radiation exposure. True Personnel should stand as close as possible to the X-ray source to reduce exposure. False 3 Film badges and dosimeters are used to monitor radiation exposure. True Lead gloves provide complete protection against radiation exposure. False X-ray photons can travel in straight lines but may scatter upon interaction with matter. True The anode in an X-ray tube is positively charged. True Proper collimation reduces patient dose and improves image contrast. True Increasing SID (Source-to-Image Distance) decreases image magnification. True 4 The primary purpose of a grid is to absorb scatter radiation.
