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. Alpha particles are a highly ionising form of particle radiation. Nuclear Radiation. Looks like you’ve clipped this slide to already. R226. Radioactivity. Created: Jun 11, 2009. How can I re-use this? The greater the likelihood that damage will occur by an interaction is the ionizing power of the radiation.
