Odorless, colorless, and tasteless, it is a dangerous gas because it can accumulate in enclosed spaces\u2014such as homes and workplaces\u2014without being detected, unless specific measuring instruments are used. Although naturally present, its concentration can become harmful to human health.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n<p><strong>Where is Radon Found?<\/strong><\/p>\n<p data-start=\"506\" data-end=\"786\">Radon is mainly released from the soil and can infiltrate buildings through cracks in floors, walls, pipes, or other openings. The most affected areas are basements and lower floors, although upper floors can also be exposed, albeit to a lesser extent. Radon can also be found in:<\/p>\n<ul data-start=\"788\" data-end=\"1187\">\n<li data-start=\"788\" data-end=\"947\">\n<p data-start=\"790\" data-end=\"947\"><strong data-start=\"790\" data-end=\"804\">Well water<\/strong>: Water extracted from underground sources can contain radon, which is released into the air when the water is used for cooking or showering.<\/p>\n<\/li>\n<li data-start=\"948\" data-end=\"1062\">\n<p data-start=\"950\" data-end=\"1062\"><strong data-start=\"950\" data-end=\"972\">Building materials<\/strong>: Some construction materials, such as tuff or granite, can emit small amounts of radon.<\/p>\n<\/li>\n<li data-start=\"1063\" data-end=\"1187\">\n<p data-start=\"1065\" data-end=\"1187\"><strong data-start=\"1065\" data-end=\"1089\">Public water systems<\/strong>: Although in smaller quantities compared to other sources, tap water may contain traces of radon.<\/p>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-797 size-full\" src=\"https:\/\/radon-sardegna.it\/en\/wp-content\/uploads\/sites\/3\/2024\/11\/infiltrazioni-radon-copy-e1732363621129.png\" alt=\"\" width=\"600\" height=\"476\" \/><\/p>\n<hr \/>\n<p><strong>Presence of Radon in Everyday Environments<\/strong><\/p>\n<p>Radon is naturally present in outdoor air at generally low and harmless concentrations. However, in enclosed environments it can accumulate and reach high levels, posing a significant health risk. Private homes, as well as public buildings and workplaces, can be particularly vulnerable\u2014especially in areas where the soil contains high levels of uranium.<\/p>\n<hr \/>\n<p><strong>Health Effects of Radon<\/strong><\/p>\n<p data-start=\"1632\" data-end=\"1991\">Prolonged exposure to high levels of radon is considered one of the leading causes of lung cancer after smoking. Inhaling radon and its radioactive decay products can damage lung tissue, increasing the risk of developing lung cancer. According to the World Health Organization (WHO), radon is responsible for approximately 3\u201314% of lung cancer cases globally.<\/p>\n<p data-start=\"1993\" data-end=\"2186\">Smokers and former smokers are particularly vulnerable, as the combined effect of smoking and radon exposure significantly increases the risk of lung cancer compared to exposure to radon alone.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p><strong>Reference Values and Regulations<\/strong><\/p>\n<p data-start=\"2231\" data-end=\"2409\">In Italy, reference values for radon concentrations in buildings are established by both European and national regulations.
