Standard - Mätning av radioaktivitet i omgivningen - Luft: radon 222
Sometimes radon enters the home through well water. In a small number of homes, the building materials can give off radon, too. However, building materials Radon exposure can happen in any type of home, whether it has a basement, a crawl space, or is built on a slab. But it’s more likely to accumulate in homes that are: very well insulated Elevated radon levels does not mean your home is unfixable. Depending on the size and design of the home and the type of the foundation, mitigation systems can be installed for under $2000.
Radon testing is easy and inexpensive and it could save your life. One thought on “ Report on Population Dose (Radon-222) – Gauteng ” GORDON says: I worked for many years in several US federal nuclear facilities, mostly US Department of Energy sites, mostly on the clean-up side of the operations, and grew up in Los Alamos, NM, USA in a family doing nuclear weapons work. Radon-222 is the most important and most stable isotope of radon. It has a half-life of only 3.8 days , making radon one of the rarest elements since it decays away so quickly. An important source of natural radiation is radon gas, which seeps continuously from bedrock but can, because of its high density, accumulate in poorly ventilated houses. Radon-222 is one of the elements in the long radioactive decay chain from uranium-238, and the less common isotope radon-220 is part of the decay series from thorium-232. The elements above radon in the chain are relatively long-lived and of less concern for radiation exposure, but radon and the elements immediately following it in the chain are short-lived and therefore more hazardous.

If there is radon in the ground below your home, it will find its way through cracks, gaps, and porous materials into your home. How to Reduce Radon. Radon is a colourless, odourless radioactive gas that naturally occurs in the soil due to the breakdown of uranium.
Radon - Hållbart Byggande
– Radon is the second-leading cause of lung cancer for the general population in the USA, and the leading cause among non-smokers (These are never smokers or people who have not smoked for 25 years). The resulting distribution of annual-average radon-222 concentrations can be characterized by an arithmetic mean of 1.5 picocurie per liter (55 becquerels per cubic meter) and a long tail with 1 to 3% of homes exceeding 8 picocuries per liter, or by a geometric mean of 0.9 picocurie per liter and a geometric standard deviation of about 2.8.
If you're wondering what a safe level of radon is, the simple answer is zero. The United States Environmental Protection Agency (EPA) notes that there are health risks of radon gas at all levels.

(Sometimes under $1000.) If you are concerned about radon levels in your home, consider conducting a long term test. AccuStar’s Alpha Track radon test The radon source you should be most wary of is the soil beneath your home. Radon is created from the decay of radioactive elements that naturally occur in rocks and stones in the soil. If there is radon in the ground below your home, it will find its way through cracks, gaps, and porous materials into your home. Radon is a gas (radon 222) released from the ground that enters homes and buildings. By itself, radon does little harm, but it decays, releasing α particles, to polonium 218 and lead 214.
