Jalokaasulle tyypillisesti radon ei muodosta normaaleissa olosuhteissa yhdisteitä. Radon syntyy maankuoressa uraanin ja toriumin hajoamistuotteena. Radonin pysyvimmän isotoopin 222 Rn puoliintumisaika on 3,8 päivää. Radon aiheuttaa terveyshaittoja rakennuksissa. Radon-222 is a decay product of radium-226 of the uranium-238 series and can be found in rocks and soil. It is an odourless, tasteless, colourless noble gas that occurs naturally in air.

226 Ra decays to a noble (inert) gas, 222 Rn. Because it is a noble gas, radon diffuses through the soil to reach the atmosphere and is mostly breathed in and breathed out.

Relativ atommassformel. Hur man beräknar atommassa. Den

Radioactivity is, and always has been a part of the earth. Radon-222 is one of the elements in the long radioactive decay chain from uranium-238, and the less common isotope radon-220 is part of the decay series from thorium-232. The elements above radon in the chain are relatively long-lived and of The equation for the alpha decay of radon-222 takes the following form. Radon-222 ----> He + Polonium. In an alpha decay, the atom loses 2 neutrons and 2 protons. So, The initial amount of radon-222 was mg, so We use the continuous decay formula to find the value after days: So 59.5115 mg of radon-222 will remain. Using the data in (Figure) , how much radon-222 will remain after one year?
