This unit addresses the critical aspects of radiobiology and radiation protection specifically for radiographers and patients. It details the biological effects of radiation exposure, including deterministic and stochastic effects, and outlines the principles of radiation physics relevant to medical imaging. The content focuses on practical methods for minimizing radiation dose to both healthcare professionals and patients during radiographic procedures, emphasizing ALARA (As Low As Reasonably Achievable) principles.

This instructional unit is designed as a component of Mosby's Radiographic Instructional Series, suggesting a focus on educational content for radiography students and professionals. The emphasis on patient protection and radiobiology indicates a curriculum-driven approach, likely providing foundational knowledge and practical guidelines for safe imaging practices. The technical specifications regarding compatibility with older operating systems (Windows 95/98) suggest it is an older digital resource.
