Radioactive Decay

Subject: Chemistry

Book: General Chemistry

Radioactive decay is the spontaneous transformation of an unstable nucleus into a more stable configuration. Common decay modes include alpha (α) emission, beta (β) emission, and gamma (γ) radiation. Decay rates follow first-order kinetics, characterized by half-life. Applications range from radiometric dating (e.g., carbon-14 dating) to nuclear medicine (e.g., using radioactive isotopes for diagnostic imaging).
