25 sty 2023 · Radon is a naturally occurring radioactive gas which may be found in high concentrations in indoor environments, such as homes and workplaces. Radon is one of the leading causes of lung cancer. Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking prevalence.
A naturally-occurring gas formed as a decay product of radium, radon is one of the densest substances that remains a gas under normal conditions, and is considered to be a health hazard due to its radioactivity. Its most stable isotope, radon-222, has a half-life of 3.8 days.
1 lip 2019 · Epidemiological studies regarding residential radon exposure and the risk of lung cancer in the general population usually use the average concentration of radon gas per cubic meter (Bq/m 3 or pCi/L, where 1 pCi/L is equal to 37 Bq/m 3) of indoor air over the period of individual residence.
7 sie 2024 · Radon is a radioactive gas you can't see, feel, taste, or smell. It forms naturally when uranium — a heavy metal found in the ground and most rocks on the planet — decays, turning into...
5 lip 2013 · Radon-222 is a naturally occurring radioactive gas that is responsible for approximately half of the human annual background radiation exposure globally. Chronic exposure to radon and its decay products is estimated to be the second leading cause of lung cancer behind smoking, and links to other forms of neoplasms have been postulated.
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.
7 cze 2021 · The repetitive inhalation of radioactive radon-222 (222 Rn) gas is the foremost cause of lung cancer in North America and Europe among people who have never smoked and causes many thousands...
