ADVANCING RADIATION SAFETY IN RADIOLOGY: DEVICES, PRINCIPLES AND PRACTICES

Abstract

This chapter on radiation safety devices explores the critical role of such devices in modern healthcare, where ionizing radiation is commonly used for diagnostic imaging. Beginning with an introduction to the importance of radiation safety, the chapter delves into various types of devices and their functions. Lead aprons, gonadal shields, thyroid shields, protective eyewear, lead gloves, tube curtains, and mobile shields are discussed in detail, emphasizing their compositions, applications, and considerations for usage and maintenance. This chapter highlights the ALARA principle, guiding the management of radiation exposure in medical imaging. It underscores the significance of justification and optimization in minimizing radiation doses while maintaining diagnostic quality. Additionally, it emphasizes the importance of dose monitoring, regulatory compliance, education, and continuous improvement in radiation safety practices. Collimators and Automatic Exposure Control (AEC) devices are explored as key components in radiation safety, providing precise control over X-ray beams and optimizing exposure parameters based on patient anatomy. The benefits of proper collimation and AEC implementation are discussed, alongside regulatory considerations and technological advancements in these areas. Overall, the chapter serves as a comprehensive guide to understanding radiation safety devices, principles, and practices in radiology, highlighting their crucial role in mitigating risks associated with ionizing radiation exposure while ensuring optimal diagnostic outcomes and personnel safety.
