Nuclear Decay (Radioactivity) Subatomic particles Electron -negatively charged particle found outside the nucleus. Marie and Pierre Curie also studied it. Uses of Radioactive Isotopes Including Safety Precautions As its ionising power is so high it does not penetrate very deeply into matter before its energy has been used up. Much of the threat from radiation is involved with the ease or difficulty of protecting oneself from the particles. 36. Radioactivity • The nuclei of naturally occurring heavy elements like U, Th, Ra and Po are unstable and keep on emitting spontaneously invisible rays or radiations (α, β, γ -rays) and give more stable elements.
