Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only 222 Rn has a sufficiently long half-life (3.825 days) for it to be released from the soil and rock where it is generated.
18 sie 2023 · One source of natural radiation that presents a danger is radon — a radioactive gas with no colour, smell or taste. It is released from bedrock material and passes through the soil. It then tends to dilute in the air, so outdoors, radon poses no harm to human health.
27 wrz 2024 · Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. It is a colorless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen. Learn more about radon in this article.
Gases given off by the radium compound are collected in a glass tube. Oxygen, nitrogen, water vapor, carbon dioxide, and other gases are removed from the gas in the tube. The gas that remains is pure radon.
25 sty 2023 · Radon is a naturally occurring radioactive gas which may be found in high concentrations in indoor environments, such as homes and workplaces. Radon is one of the leading causes of lung cancer. Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking prevalence.
Radon gas, a naturally occurring radioactive gas, emerges from this subterranean realm, a product of the inexorable decay of uranium found in soils, rocks, and water. This decay is not confined by borders or barriers, resulting in radon levels that vary globally, influenced by the Earth’s patchwork of natural uranium deposits.
1 mar 2019 · Updated on March 01, 2019. Atomic Number: 86. Symbol: Rn. Atomic Weight: 222.0176. Discovery: Fredrich Ernst Dorn 1898 or 1900 (Germany), discovered the element and called it radium emanation. Ramsay and Gray isolated the element in 1908 and named it niton.
