För höga halter av radon | Ergo photo ICNTS conference, ID 191 Alpha-track radon measurements at . 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. 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.

Radon, Rn-222 (half-life = 3.82 days), is a daughter product of radium, Ra-226, which in turn is derived from the longer-lived antecedent, U-238. Thoron, Rn-220 (half-life = 56 seconds) is a daughter of thorium as shown in Figure 2.2, Th-232, which is present in larger amount in the earth’s crust than radon. Radon-222 atom is a radon atom. Radon is a naturally occurring radioactive gas that is odorless and tasteless.

If we know that Radium 226 is an alpha emitter, we can figure out the other product:. Top: 226=222+4 Bottom: 88= 86 + 2. The element radon is the only element The chart below lists all of the decay products of radon gas (radon-222) in their Each radioactive element on the list gives off either alpha radiation or beta Radon emits alpha radiation and has a short half-life, meaning that it α. Radon- 222. Lead-206. Polonium- 210.

The experiment uses a charged balloon to extract the dust (and any radionuclides residing on it) from the air. The radiation level of the balloon is monitored by a Geiger counter and the half-life of the decay products is observed. How it works: All of the heavy elements (Z>83) found in nature are radioactive and decay by alpha or beta emission. The alpha decay of Radon (atomic number = 86) alters the identity of Radon leading to emission of an alpha particle (He nucleus).
