Radiobiology (also known as radiation biology, and uncommonly as actinobiology) is a field of clinical and basic medical sciences that involves the study of the effects of ionizing radiation on living things, in particular health effects of radiation.

Radiation biology is a primary concept underlying the practice of radiation oncology, and understanding the principles of radiation biology is essential for radiation oncologists to understand the effects of radiation therapy on the body.

Radiation biology is the study of the effects of ionizing radiation on biological tissues and living organisms. It combines radiation physics and biology. The purpose of this chapter is to introduce the terminology and basic concepts of radiobiology to create a...

4 Basic Principles of Radiation Biology To understand how ionizing radiation can damage biologic systems, it is necessary to understand what ionizing radiation is and how it interacts with tissues in the body.

Introduction - Effects of irradiation on Cells Radiobiology is the scientific study of the effect of ionizing radiation on cells and tissues (a "young science") dating from the 1950s. Dose and fractionation schedules were determined empirically, before radiobiology. Oxygen Effect (Gray, 1953) has not resulted in increased cure rates.

The goal of radiobiological research is to better understand the effects of radiation exposure at the cellular and molecular levels in order to determine the impact on health.
