Radon-220 (Thoron) decay chain

Solving a system of differential equations according to Bateman to calculate the rel. activity of the products of the Rn-220 decay chain.

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".
