You can detect radiation in seconds. Understanding what it does to the human body can take far longer. This gap defines a leading challenge of radiation biology, the field that studies how radiation interacts with living systems. 

In this episode, Dr. Marc Mendonca, Associate Vice President of Research at the University of Central Florida, joins host Dr. Arun Seraphin to discuss what problems radiobiologists are attempting to solve, and how these problems shape the realities of warfighters, first responders, cancer patients, astronauts, and civilians. The conversation highlights persistent limits in assessing how much radiation an individual has actually absorbed, how their body will respond, and why so many sectors rely on better understanding these effects. It also examines the operational strain created by the “walking well” in mass exposure scenarios.

Mendonca outlines key research gaps in the field, including radiation’s influence on the immune system, the mechanisms behind radiation-induced cancer, the need for effective post-exposure mitigation, and the development of faster, field-ready diagnostic tools.
