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.
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.
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.
5 lip 2013 · Radioactive decay occurs in unstable atomic nuclei with the emission of ionizing particles resulting in a release of energy. With a half-life of 3.82 days, radon can accumulate in buildings before rapidly decaying into lead-210 with a half-life of 22 years.
18 sie 2023 · IAEA safety standards establish concentrations of radon in homes and at workplaces to protect the people’s health. What are the risks from exposure to radon? Radon accounts for around a half of all human exposure to radiation.
Infographic. Radiation: Key risks to health. Radon is a naturally occurring radioactive gas. It has no smell, colour or taste, and is produced from the natural radioactive decay of uranium in rocks and soil. Radon can also be found in water.
16 lut 2024 · Radon is an odorless and invisible radioactive gas naturally released from rocks, soil, and water. Radon can get trapped inside homes and buildings, and build up in the air. Over time, breathing in high levels of radon can cause lung cancer.
