Alpha Decay of Radon-222

222Rn → 218Po + 4He

अवलोकन

Radon-222, a radioactive noble gas, alpha decays to polonium-218 with a half-life of 3.82 days. As the densest naturally occurring gas, radon accumulates in basements and enclosed spaces. Its short-lived decay products (Po-218, Po-214) deposit in lungs and cause radiation damage.
