Radon-222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon. [1] Its final decay product is stable lead-206. In theory, 222 Rn is capable of double beta decay to 222 Ra, and depending on the mass measurement, single beta decay to 222 Fr may also be allowed.
There are 39 known isotopes of radon (86 Rn), from 193 Rn to 231 Rn; all are radioactive. ... Isotopic mass [3] [n 2] [n 3] Half-life Decay mode Daughter isotope Spin ...
Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless [47] noble gas, occurring naturally as the decay product of uranium or thorium. Its most stable isotope, 222 Rn, has a half-life of 3.8 days. Radon is one of the densest substances that remains a gas under normal conditions. It ...
