Americium-241 Alpha Decay

241Am → 237Np + 4He

अवलोकन

Americium-241 alpha decays to neptunium-237 with a half-life of 432 years, also emitting a 59.5 keV gamma ray. Am-241 is the most common household radioactive source, present in virtually every smoke detector. A tiny amount (about 1 microgram) ionizes air between two plates.
