Radiation's interaction with living tissue is not uniform — some cells and systems are more vulnerable than others. This property, known as radiosensitivity, is central to understanding diagnostic imaging, radiation therapy, and radiation protection principles. For those preparing for the ARRT Registry, mastering this concept is essential.

In this second part of our blog series on the biological effects of radiation, we will explore the factors that influence radiosensitivity, including dose-response r...
