Скачать или смотреть Basics of Radiation Physics – Part III | Half-Life & Radioactivity Formulas Explained | Lecture 11

Welcome to Lecture 11 of the Radiology & Medical Physics series!
In this part of Basics of Radiation Physics, we focus on the mathematical aspects of radioactivity—understanding and applying the formulas of half-life, decay constant, and activity used in radiology and nuclear physics.

📖 Topics Covered in This Lecture:
🔹 Concept of radioactive decay and exponential law
🔹 Derivation and use of half-life (T½) = 0.693/λ
🔹 Relationship between decay constant (λ), activity (A), and number of atoms (N)
🔹 Units of radioactivity — Curie (Ci), Becquerel (Bq)
🔹 Sample problems and numerical understanding
🔹 Clinical and diagnostic applications of half-life in radiology and nuclear medicine

This lecture helps you clearly understand how radioactive decay equations are used in imaging physics, dosimetry, and isotope studies — essential knowledge for every medical student and radiology resident.
