Answers


John
Radioactivity or radioactive decay is the spontaneous disintegration of unstable nuclides to form stable ones with the emission of radiation. Unstable nuclides continue to disintegrate until a stable atom is formed.
Alpha (${\alpha}$) and beta (${\beta}$) particles are emitted and the gamma rays (${\gamma}$) accompany the ejection of both alpha and beta particles.
