1 cze 2024 · Beyond tobacco smoking, radon takes its place as the second most significant contributor to lung cancer, excluding hereditary and other biologically related factors. Radon and its byproducts play a pivotal role in exposing humans to elevated levels of natural radiation.
Radon (222Rn) is naturally occurring radioactive gas. It is produced and decays by alpha emission to a polonium isotope (218po) which further decays is an isotope of lead, bismuth and polonium ends with a stable isotope of lead (206pb), Figure 2 shows alpha decay properties of radon which short-lived decay products [7].

Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only 222 Rn has a sufficiently long half-life (3.825 days) for it to be released from the soil and rock where it is generated.
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.
