The alpha decay of 232 Th initiates the 4n decay chain which includes isotopes with a mass number divisible by 4 (hence the name; it is also called the thorium series after its progenitor). This chain of consecutive alpha and beta decays begins with the decay of 232 Th to 228 Ra and terminates at 208 Pb.

WebRadon is made up of three unstable isotopes from each of the three natural radioactive disintegration series (Uranium, Thorium and Actinium)[4]. To differentiate it from the other two natural isotopes, Thoron (Rn-220) and Actinon (Rn-222), the (Rn-222) isotope is given the name Radon (Rn-219), which come from the Thorium and
