Radioactive pollution occurs when radioactive materials are released into the environment through human activities like nuclear weapons production, mining radioactive ores, medical waste disposal, and accidents at nuclear power plants. Natural sources of radiation also exist like cosmic rays and terrestrial radiation. Exposure to radiation can damage DNA and lead to health issues like burns, cancers, and death over long periods of time or with high doses. Prevention of radioactive pollution is important through strict safety measures, monitoring, efficient waste disposal, and developing alternative energy sources to reduce nuclear power usage.
