Radiation & Energy Basics Exam Q&A 80+ Questions – RAD105 Physics Concepts Radiation Protection Energy Formulas

This document provides a comprehensive collection of over 80 exam-style questions and verified answers covering fundamental concepts in radiation physics and energy principles. It is designed to support students in mastering both theoretical physics foundations and their application within radiography and medical imaging contexts. The material begins with core definitions such as matter, mass, energy, and different forms of energy (page 1–2), and progresses into key radiation concepts including ionizing vs non-ionizing radiation, electromagnetic energy, and sources of background radiation (page 3) . It also explores essential principles of radiation protection, including ALARA, NCRP, ICRP guidelines, and protective measures like shielding and filtration (page 4–5). In addition, the document covers important physics formulas and mechanics concepts such as kinetic energy, gravitational potential energy, force, work, power, and momentum, along with temperature conversion and heat transfer mechanisms (pages 6–8). The content is highly aligned with foundational textbooks such as Radiographic Imaging and Exposure by Terri L. Fauber and Introduction to Radiologic and Imaging Sciences and Patient Care by Arlene M. Adler and Richard R. Carlton. It is particularly suitable for students enrolled in Radiography (RAD105/RAD106), Medical Imaging, Radiologic Technology, and Health Sciences programs. This document is ideal for radiography students, imaging students, and allied health learners preparing for physics exams, coursework assessments, or registry-level examinations such as ARRT, offering both conceptual clarity and exam-focused practice.
