24 cze 2023 · This review study examines the relationship between radon and geology, including its origins, transmission, and accumulation, as well as its impact on human health and mitigation strategies. The decay of uranium and thorium produces radon, a radioactive gas.
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.
5 lip 2013 · Introduction. Radon-222 (further referred to as radon) is a naturally occurring inert gas formed in the decay series of uranium-238 (Figure 1), which can be found in trace amounts in many rocks and soils.
The curie is the amount of radioactive materials in which 37 billion disintegrations (decay events) occur each second (3.7×10 10 transformations per second). In discussing radon, a smaller unit, the picocurie (pCi), is used, where 1 pCi=1×10 −12 Ci.
1 cze 2024 · More than 85 % of radiation-related lung cancer deaths occur among smokers, and smokers have a 10- to 20-fold increased risk of lung cancer from radon exposure compared to nonsmokers (Lantz et al., 2013). Thus, radon exposure and smoking have synergistic effects on lung cancer development.
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 · 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.
