What is the connection between Uranus and Radon?

uranium and radon are naturally occurring radioactive elements. Radon is a heavy gas that is a temporary product of uranium decay. Uranus present in the rocks is subject to the sequence of alpha and beta disintegration through a number of unstable isotopes of various elements, eventually ending, eventually with a stable isotope lead. Rock contains a small but variable amount of uranium, granite has a relatively high level. For this reason, uranium and radon levels tend to be high in granite areas; However, other factors are influenced by the actual levels of radon gas reaching the surface. The isotope created by this process is the Radon-222, which is unstable and emits the alpha particle, creates a polonium-218, another isotope in the sequence. The Radon-222 has a half-life of 3.8 days, which means that after this period half of the saradon will disintegrate. Unlike the "enriched" uranium used in nuclear reactors, the naturally occurring Uran-238 is only slightly radioactive. Normally does not pose a threat, although C ishemically toxic if it is used. Radon is a more serious danger because it is highly radioactive and can easily escape from the subsoil and accumulate in homes where it can be inhaled.

both uranium and radon are produced by alpha particles. Although these particles cannot penetrate the skin if they come into contact with living tissue, they can cause damage. When DNA is damaged, this can lead to cancer. If Radon is inhaled, it is likely that it will get into contact with lung tissue and long -term inhalation of radon in households can lead to chronic lung disease and lung cancer. Most lung cancer is caused by smoking, but Radon is the second biggest cause.

Radon levels in households depend on a number of factors in addition to the uranium content in the subsoil. While the gas will tend to rise towards the surface due to pressure differences, it can do it faster if the subsoil is present in their sourceOMENINY, and if the soil and pad are very permeable. However, moisture slows its progress as it can dissolve in water. After reaching the surface, it can be drawn into households, especially if the foundations are not well sealed, climbing heated inner air and accumulation due to limited circulation.

Measurement for natural radioactivity is usually Picocuria (PCI), which is roughly equivalent to the decay of two atoms per minute. Radon levels in the air are usually expressed as picocuria per liter of air (PCI/L). Typical for outdoor air is about 0.4 pci/l, but the internal levels tend to be higher, with 1.3 pci/l to be a diameter. Level 4 PCI/l or highjeje is considered a health risk.
