Alpha Decay of Radium-226

概要

Radium-226 emits an alpha particle to form radon-222 gas. Radium was discovered by Marie and Pierre Curie in 1898 and was the first radioactive element isolated in pure form. Marie Curie won two Nobel Prizes for her work on radioactivity. Radium's decay produces radon, a radioactive gas.
