In this study, electrical-nuclear reduplication was modeled by the similarity of decay equations with corresponding circuit equations to find an equivalent circuit for decay chain of radon-222. Each step was implemented along with the corresponding geometric diagram through a reduplication process in ...
222Rn is preceded in the 238U decay series by radium (226Ra), which has a half-life of 1600 years. 226Ra decays to stable lead (206Pb), producing a chain of radioactive isotopes of solid elements. The decay chain of 238U is shown in Figure 1. Sign in to download full-size image ...
radon-222, and radon-220. Radon-222 is a member of the radioactive decay chain of uranium-238. Radon-220 is formed in the decay chain of thorium-232. Radon-222 decays in a sequence of radionuclides called radon decay products, radon daughters, or radon progeny. It is radon-222 that mo...
Radon mostly appears with the decay chain of the radium and uranium series (222Rn), and marginally with the thorium series (220Rn). The element emanates naturally from the ground, and some building materials, all over the world, wherever traces of uranium or thorium can be found, and parti...

Isotopes of radon There are thirty four known isotopes of Radon (Rn). The most stable isotope is 222Rn, which is a decay product (daughter product) of 226Ra,
In 1899, Robert B. Owens and Ernest Rutherford found a radioactive gas emanating from thorium[1]. In that same year, Marie and Pierre Curie detected a gas being released by radium[1]. In 1900, Ernst Dorn discovered a gas while studying the decay chain of radium at the German city of ...
Beta radiation from the 222Rn decay chain interferes with BAM measurements of fine particles; thus, some BAMs incorporate radon measurements into their sampling systems. BAMs are ubiquitous in air quality monitoring networks globally and present a hitherto unexplored source of dense, continuous radon ...
This decay chain is governed by the relatively long half-life of Rn222Rn222, at 3.8 d—the longest half-life of all radon isotopes. The α-emitters of this decay chain contribute the most to the total dose, whereas β- and γ-decay are only responsible for less than 10% [6]. ...
