Radiation Protection in Medical Imaging- Study Guide Questions and Answers Latest Version (2024/2025) Already Passed

Radiation Protection in Medical Imaging- Study Guide Questions and Answers Latest Version (2024/2025) Already Passed Why should radiology departments use the "3 Rs" (Reduce, Replace, Refine) in radiation protection? To minimize radiation exposure by reducing the number of imaging procedures, replacing harmful techniques with safer alternatives, and refining imaging protocols for optimal safety. How does patient size impact radiation dose in medical imaging? Larger patients may require higher radiation doses to produce clear images, making it even more important to use shielding and proper collimation. What is the role of a lead thyroid shield in protecting patients during X-ray procedures? A lead thyroid shield protects the thyroid gland from radiation exposure, which is sensitive to radiation. What is the correct way to handle a radiology procedure involving a pregnant patient? 2 Always consult with the referring physician, assess the necessity of the procedure, and use appropriate shielding if the imaging is required. What type of radiation is most commonly used in diagnostic imaging? X-rays are the most common form of radiation used in diagnostic imaging procedures. Which of the following is an effective method to reduce radiation exposure during X-ray imaging? Using the lowest possible radiation dose and appropriate shielding techniques. What is the function of lead aprons in radiology? Lead aprons are used to protect sensitive organs from unnecessary radiation exposure during imaging procedures. How can the time of exposure be minimized in medical imaging? By reducing the duration of the imaging procedure and using the fastest imaging techniques available. What is the ALARA principle in radiation protection? 3 The ALARA (As Low As Reasonably Achievable) principle aims to minimize radiation exposure by optimizing techniques and protective measures. Why is distance important in radiation protection? Increasing the distance from the radiation source decreases exposure, as radiation intensity decreases with distance. What type of shielding is commonly used in medical imaging to protect patients from unnecessary radiation? Lead shielding is commonly used due to its effectiveness in absorbing and blocking ionizing radiation. Which of the following is the best practice for radiology staff to avoid unnecessary radiation exposure? Wear personal dosimeters, follow safety protocols, and use shielding devices when possible. What is a common source of radiation exposure in medical imaging environments? X-ray machines, fluoroscopes, and CT
