6 lip 2023 · The transfer factor of radionuclides such as uranium, thorium, radium, and radon from soil to plants and their distribution among different parts of the plant depends on the soil nature and...
1 lip 2019 · Through many epidemiological studies regarding occupational exposure among miners and residential exposure among the general population, radon has been scientifically proven to cause lung cancer, and radon exposure is the second most common cause of lung cancer after cigarette smoking.
18 sie 2023 · Radon occurs naturally in significant quantities in three different chemical variations, or isotopes, but only two of these present a risk. Radon-222 — a product of Uranium-238 or Radium-226 decay — is the most dangerous one.
25 cze 2018 · The effects of IR on plants are understood best at acute high doses because there have been; (a) controlled experiments in the field using point sources, (b) field studies in the immediate aftermath of nuclear accidents, and (c) controlled laboratory experiments.
Właściwości fizyczne. Radon jest bezbarwnym, bezwonnym radioaktywnym gazem szlachetnym. Występuje naturalnie, jako produkt rozpadu radu, który z kolei powstaje z obecnego w przyrodzie w sporych ilościach uranu. Jego najstabilniejszy izotop 222 Rn ma okres połowicznego rozpadu 3,8 dnia i jest stosowany w radioterapii.
21 wrz 2009 · Radiation: Key risks to health. Radon is a chemically inert, naturally occurring, radioactive gas. It has no smell, colour, or taste, and is produced from the natural radioactive decay of uranium which is found in rocks and soil.
From the highest mountains to the deepest wells, radon’s presence is as widespread as the uranium from which it originates. Understanding where radon comes from is the first step in comprehending its potential impact on indoor air quality and, consequently, on our health.
