Functions. Solving a system of differential equations according to Bateman to calculate the relative activity of the products of the Rn-220 decay chain. Radon-220 or Thoron is a natural decay product of thorium. For the basics have a look at "Radioactive decay & Bateman equation".

Thoron, Rn-220 (half-life = 56 seconds) is a daughter of thorium as shown in Figure 2.2, Th-232, which is present in larger amount in the earth’s crust than radon. There are 37 known isotopes of radon (86 Rn), from 195 Rn to 231 Rn; all are radioactive.The A radon isotope ( 220 Ra, called thoron) is also produced in the decay chain of 232 Th but its half-life is very short (t½ = 55 s) and it cannot accumulate as effectively as 222 Ra. The radon isotope 219 Ra (or actinium) is also produced in the decay chain of 235 U, but its half-life is still shorter (t½ = 4 s).

220 Rn is a decay product of the long-lived 232 Th isotope. The half life of 232 Th is 14 billion year. Thorium occurs in thorite and in thorianite and is thought to be about three times as abundant as uranium and about as abundant as lead.
