  Radiation ,  The transmission of energy through space or matter, surrounds us daily, both naturally and artificially. Natural sources include sunlight, cosmic rays, and radioactive elements in soil and rocks. Man-made sources encompass medical procedures like X-rays and CT scans, nuclear power plants, and industrial processes. While radiation has countless beneficial applications, including medical diagnosis and cancer treatment, it also carries risks. Ionizing radiation, such as X-rays and gamma rays, can damage cells and DNA, potentially leading to radiation sickness or cancer. Non-ionizing radiation, like radio waves and visible light, typically poses fewer health risks but can still cause tissue heating and other effects with prolonged exposure. Understanding radiation's properties, sources, and effects is essential for mitigating risks and maximizing benefits. Safety measures such as shielding, monitoring, and regulatory controls help minimize exposure in medical, occup...
