Radon 222

2020 — Radon (Rn-222) är en radioaktiv gas som ingår i uranserien. Den bildas av uran (U-238) via flera sönderfall. I sönderfallskedjan är radium 14 sidor — Radon är en radioaktiv gas som bildas naturligt när uran i jordskorpan sönderfaller. Vissa bergarter, som skiffer och granit, innehåller mer radon än andra. • Vatten av J Kulich · 1988 · Citerat av 7 · 77 sidor — vattenverk.

However, even with an action level of 2.0 pCi/L, the cancer risk presented by radon gas is still hundreds of times greater than the risks allowed for carcinogens in our food and water. Radon-222 decays to a stable nucleus by a series of three alpha emissions and two beta emissions. What is the stable nucleus that is formed?

Dorn, radon-222 (3.823-day half-life), the longest-lived isotope, arises in the uranium series. The name radon is sometimes reserved for this isotope to distinguish it from the other two natural isotopes, called thoron and actinon, because they originate in the thorium and the actinium series, respectively. Radon (Rn-222) bildas i den sönderfallskedja som startar med uran (U-238) och slutar med stabilt bly (Pb-206).

Chapter 8.3 Radon General description Radon is a radioactive noble gas. Of all radon isotopes only two, radon-222 (radon) and radon-220 (thoron) occur in significant amounts indoors. Radon-222 is one of the decay products of uranium-238 (half-life 4.5 × 109 years) and radon-220, a nuclide thorium-232 decay (half-life 1.4 × 1010 years). Radon 222 CASRN 14859-67-7 | DTXSID7024295.

Radon (Rn) is an inert, radioactive gas which has several isotopes. The most important isotope in this experiment is 222 Rn, and belongs to the radioactive decay series starting with 238 U and ending 206 Pb, a stable lead isotope (see fig. 2.1). The other two isotopes that can be measured in this experiment, 220 Rn and 219 Rn, belong to different decay chains.
