Air pollution remains a major environmental issue, with many implications in several aspects of our life and the environment we live in. Dr. Evangelia Diapouli talks about the efforts of her team, at the Environmental Radioactivity Lab in the Institute of Nuclear & Radiological Sciences & Technology, Energy & Safety at NCSR Demokritos, the measurements they take daily at their research station in Athens (another one is being built at Mt. Chelmos, of the Peloponnese) and the impact of the results in our lives. Interviewed by Yannis Rizopoulos for Tech Talks Central.
