Radionuclides

Radionuclides are atoms with an unstable nucleus that releases energy or particles as they transform into more stable forms. This process, called radioactive decay, emits radiation such as alpha, beta, or gamma rays. Radionuclides occur naturally—like uranium in the Earth—and can be artificially produced for medical treatments, imaging, or industrial purposes. Their ability to emit radiation makes them useful in diagnosing and treating diseases, but they require careful handling due to potential health risks. In summary, radionuclides are radioactive atoms that change over time, releasing energy that can be harnessed for various practical applications.
