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.
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.
Radon is a member of the zero-valence elements that are called noble gases, and is chemically not very reactive. The 3.8-day half-life of 222 Rn makes it useful in physical sciences as a natural tracer. Because radon is a gas at standard conditions, unlike its decay-chain parents, it can readily be extracted from them for research. [19]
3 dni temu · Humans receive around 50% of natural radiation dose due to 222 Rn (radon), 220 Rn (thoron) and their decay products. Several field campaigns measuring these gases and the decay products in ...
The description of the element in its natural form. Biological role. The role of the element in humans, animals and plants. Natural abundance. Where the element is most commonly found in nature, and how it is sourced commercially.
Radon is a naturally occurring radioactive gas that is colorless and odorless. Radon comes from the natural decay of uranium or thorium, elements found in rocks, soils, and water. Radon breaks down quickly, giving off radioactive particles.
Radon gas escapes easily from rocks and soils into the air and tends to concentrate in enclosed spaces, such as underground mines, houses, and other buildings. Soil gas infiltration is recognized as the most important source of residential radon.
