Nuclear Radiation Effects and Hazards

This video provides an overview of nuclear hazards, their sources, and the risks they pose to human health. It explains the nature of radioactive materials, the types of nuclear pollution, and the effects on living organisms. The video also covers the sources of nuclear pollution, both natural and man-made, and discusses the somatic and genetic effects of exposure. Finally, it outlines prevention and control measures to mitigate these hazards, including safe disposal of nuclear waste and monitoring of radioactive sites.
