However, other health effects of exposure to radon progeny and to uranium mining in general have also been of concern. The health effects mentioned in the literature are nonmalignant respiratory diseases in underground miners Many studies addressed radon (Rn222) gas concentration levels in a number of locations in Jordan. But, none investigated the level of awareness of Jordanians of radon and its harmful effects on public health. In this study, a sample of 200 participants has been tested for their knowledge of radon and its effects on human health. The The Radon-222 gas penetrates through soil and rocks and dissolves in water (Xinwei, 2006). Normally, drinking water from ground water sources has higher concentration of radon than surface water. The exposure of a population to high concentration of radon and its daughters for a long period has significant health effects ranging from respiratory functional changes to cancer of the lungs (BEIR @article{osti_5730083, title = {Potential health effects of indoor radon exposure}, author = {Radford, E P}, abstractNote = {Radon-222 is a ubiquitous noble gas arising from decay of radium-226 normally present in the earth's crust.

In early 1990s, a WHO international workshop on indoor radon was a step towards a unified approach to controlling radon exposures and advising on the communication of associated health risks. Radon-222 is a ubiquitous noble gas arising from decay of radium-226 normally present in the earth's crust. Alpha radiation from inhaled short-lived daughters of radon readily irradiates human bronchial epithelium, and there is now good evidence of excess risk of lung cancer in underground miners exposed to higher concentrations. Radon is a radioactive gas released from the normal decay of the elements uranium, thorium, and radium in rocks and soil.
Vad vet vi om risker vid låga stråldoser?” av Sören Mattsson
Radon is produced directly by alpha-ray decay of an aqueous solution of radium chloride (88 Ra 226 → 86 Rn 222 + 2 He 4).
There does seem to be something to it, actually. Radon-222 is the longest-lived isotope of the element with a half-life of 3.8 days. It is a member of all three natural radioactive series. Radon is produced directly by alpha-ray decay of an aqueous solution of radium chloride (88 Ra 226 → 86 Rn 222 + 2 He 4). The solid decay products of radon (Tn-222, Po-218 and Pb-214) can attach to particles in the air and travel long distances in the atmosphere. Rn-222 has a radioactive half-life of about 4 days.
