The discovery of X-rays by Wilhelm Roentgen revolutionized medical diagnostics and treatment. These electromagnetic waves, with their ability to penetrate materials, are used in radiography, CT scans, fluoroscopy, and mammography. While beneficial, X-rays pose health risks due to their ionizing nature, necessitating protective measures to minimize exposure and potential cellular damage.
