Each of the decay product isotopes in the decay chain has its own half-life, and once it is formed it begins its decay to the next isotope in the sequence. The half-life of radon-222 is only 3.8 days. Some isotopes in the 238U decay chain series have half-lives on the order of minutes, and for polonium-214 it is only 164 micro-seconds

Some isotopes in the 238U decay chain series have half-. uranium and thorium decay chains (see Figure 4-1) (Buttafuoco et al. 2007; O' Neil et al. 2006). 222 (radon), 220 (thoron), 219 (actinon) Cothern 1987a.

Rn 220 decay chain

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. 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".

Decay energies and times from pile-up events were extracted with a tailor-made pulse-shape analysis routine and specific α-decay chains were identified in a correlation analysis. Decay chains starting with the even-even 220 Ra and its odd- A neighbors, 219 Fr, and 219,221 Ra, with a focus on the 219 Ra→ 215 Rn decay, were studied by means of α-γ spectroscopy.

226 Ra occurs in the decay chain of 238 U (often referred to as the radium series). Radium has 33 known isotopes from 202 Ra to 234 Ra. 220 Rn: 225 Ra trace 14.9 d

In the Radiation Protection Act (1988:220), the term 'radioactive waste' is used for radioactive is to allow the thermal output to decay by about 90 per cent before encapsulation and disposal chain is relatively similar in terms of the role of SOS Alarm AB.
