These daughter nuclei have a lower mass and are more stable (lower in energy) than the parent nucleus. Nuclear decay is also called radioactive decay, and it occurs in a series of sequential webpage-http://www.kentchemistry.com/links/Nuclear/naturalTrans.htmThis short video walks you through how to write an alpha decay expression. I explain how t This paper presents an experimental approach to evaluate the effectiveness of unipolar ionizers in indoor environment for the removal of thoron (²²⁰Rn) daughter products. Both continuous and instantaneous source conditions were simulated during these experiments.

The gas thoron, or thorium emanation, is an isotope of radon (86 Rn 220) which decays by α emission and has a half life of 55.6 seconds. 2 Using an emanation electroscope, we observe the radioactive decay of thoron (separated from all its parent substances) by the progressive decrease of ionization in the air around the thoron. Ra-224 decays mainly by alpha emission to the ground and 240.986-keV nuclear levels of Rn-220. A small C-14 cluster decay branch of 5E-9% has also been observed. Write a partial decay series for Rn-220 undergoing the sequential decays: α, α, β, α..
