Radon. is a radioactive gas with a half life of 3.8 days.
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.
Radon compounds can be formed by the decay of radium in radium halides, a reaction that has been used to reduce the amount of radon that escapes from targets during irradiation. [24] Additionally, salts of the [RnF] + cation with the anions SbF − 6, TaF − 6, and BiF − 6 are known. [24] Radon is also oxidised by dioxygen difluoride to RnF ...
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.
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.
