What is Radioactivity and Is It Always Harmful: Explained in Really Simple Words
Radioactivity is the property through which a heavier, unstable nucleus assumes a more stable state by emitting radiation. The process through which a nucleus turns into a stable one is called radioactive decay. But is radioactivity or...
