This script was written for autodidactic purposes. Maybe someone else will find it useful. Abstract. For the renewal of dose estimation from internal irradiation in the high background radiation areas (HBRA) of Yangjiang, the measurements of radon, thoron and their decay products in the environmental air were conducted, including: (1) integrating measurements of Rn-222 and Rn-220 concentrations; (2) equilibrium factor F for Rn-222 and alpha-potential energy value of Rn-220; (3 The half-life of radon-220 is 55 seconds and it decays via alpha decay to polonium-216.

Isotope data for radon-220 in the Periodic Table Detailed decay information for the isotope radon-220 including decay chains and daughter products. However, these isotopes of radon are of lesser radiological importance. The thorium series generates 220 Rn, which is also called thoron. 220 Rn has a half-life of 56 s and therefore has a much greater chance to decay before becoming airborne. There are 37 known isotopes of radon (86 Rn), from 195 Rn to 231 Rn; all are radioactive.
