Explore the alarming discovery of radioactive fallout in glacial ice sediments across the Arctic, Iceland, the Alps, the Caucasus, British Columbia, and Antarctica in this 20-minute podcast episode. Delve into the potential consequences of this nuclear legacy as climate change accelerates glacial melting, potentially releasing radioactive material into rivers, streams, and food chains. Join University of Plymouth scientist Caroline Clason as she discusses her team's findings, ongoing research questions, and the possible effects of radionuclides on ecosystems. Gain insights into the far-reaching impacts of nuclear accidents and weapons testing, and understand the complex interplay between human activities and environmental contamination.
