Radon finns i praktiken i all jord under marken. 2020-01-30 · Radon (Rn) is a radioactive, colorless, odorless and tasteless gas that occurs naturally as the decay product of the elements radium, uranium and thorium. It is a noble (or inert) gas, meaning it is inactive chemically and combines with other substances only under extreme conditions.

Owens and British scientist Ernest Rutherford, who noticed that some of the radioactivity of thorium compounds could be blown away by breezes in the laboratory. The 220 Rn isotope is a natural decay product of the most stable thorium isotope (232 Th), and is commonly referred to as thoron. It has a half-life of 55.6 seconds and also emits alpha radiation. Similarly, 219 Rn is derived from the most stable isotope of actinium (227 Ac)—named "actinon"—and is an alpha emitter with a half-life of 3.96 Rn-219: 3.96 seconds: Rn-220: 55.61 seconds: Rn-222: 3.82 days: Facts Date of Discovery: 1898 Discoverer: Fredrich Ernst Dorn Name Origin: From radium Uses: treatment Re: 220 gr Hornady RN .30-06 Post by Stigmannen » 31 Dec 2012, 15:46 Jag har provat Hornady 220 gr i min Husqvarna 1640 kal, 30-06 men räffelstigning 1:12 och det gick jätte bra.

Abstract. Thoron’s (220 Rn) contribution toα-radiation exposure is usually considered negligible compared to that of 222 Rn (radon).Despite its short half-life of 55.6 seconds, thoron can be exhaled from porous surface layers of building materials into indoor air where people subsequently inhale radioisotopes, including metallic radioactive progeny.
