Radioactive Roots: Life Finds a Way (Even if it Glows a Bit)

The Looking Glass

Nuclear catastrophes like Chernobyl and Fukushima serve as a stark reminder of the risks that come with harnessing atomic energy — we hear about the evacuations, the health impacts, the geopolitical consequences. But what about the landscapes left behind? What happens to plants, animals, and entire ecosystems when exposed to high levels of radiation over days, months, or even years? To help us unpack these questions, we're joined by Dr. Timothy Mousseau.
Dr. Timothy Mousseau is an evolutionary biologist and leading expert on the effects of radiation on wildlife in Chernobyl and Fukushima. He was the first U.S.-based biologist to begin research in Fukushima, starting in July 2011, and his pioneering work in Chernobyl has revealed a wide range of radiation-related impacts on organisms—shifting how we understand the vulnerability of natural populations to environmental contaminants. Most recently, his research has expanded to explore the effects of cosmic radiation in space. With years of fieldwork across continents, Dr. Mousseau’s findings have offered critical insights and sparked ongoing debate within the field of radioecology. Let’s explore what nuclear fallout really means for the natural world — and why this research matters now more than ever. We hope you enjoy this episode of the Looking Glass Podcast.
