Course Description

In this course, Dr. M. Mahesh breaks down the fundamentals of radiation biology, tracing radiation effects from the cellular and chromosomal levels to tissues and organs. Learners will explore the key parameters used to characterize biological effects, including relative biological effectiveness (RBE), and develop a clearer understanding of how radiation exposure translates into biological response.

The course also examines stochastic and non-stochastic effects, radiation syndromes, and radiation-induced carcinogenesis, connecting foundational science with the radiation risks encountered in medical imaging.

Take this course to better understand radiation risk, communicate its potential effects, and make informed decisions about radiation use and patient safety.
