av D Segersson · 2017 · Citerat av 82 — The most important anthropogenic sources of primary particulate matter (PM) in heavy goods vehicles (petrol and diesel) and buses (diesel, gas and ethanol).

Radon is an element which is dissolved and can sometimes be found in the water wells. You cannot smell, see, or taste radon. However, you can drink it, especially when your main water source is the water well. The activity of radon in natural gas in the reservoir is ultimately determined by the abundance of its source, 226 Ra, whose decay to 222 Rn is independent of pressure. As radon forms, it preferentially enters a gas phase (if present) and establishes a concentration dependent upon its rate of supply from 226 Ra in the reservoir and the rate of 222 Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium.

Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water.

Because radon is an unstable gas, it breaks down and dissipates quickly in the open air. Dangerous levels of radon can accumulate inside a house, however. The soil under and around the house is by far the largest source of radon gas, but it is also present in well water, building materials, public water supplies and outdoor air (see pie chart).

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. Element Radon (Rn), Group 18, Atomic Number 86, p-block, Mass [222].

Radon-222 decay products have been classified by the International Agency for Research on Cancer as being carcinogenic to humans, and as a gas that can be inhaled, lung cancer is a particular concern for people exposed to elevated levels of radon for sustained periods.

Radon is a naturally occurring radioisotope. Radioactivity is, and always has been a part of the earth. 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

Radon-222 Radon is a naturally occurring gas, and is a product of uranium decay.

This isotope of radon belongs to the radioactive lineage of uranium 238 , and Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of rare in nature because its isotopes are all short-lived and because its source, Being a gas, radon can move through cracks and spaces in the rocks and soil, a source of ground water (as opposed to surface water like rivers and streams). Since one of the sources of water contamination is nuclear contamination from radon gas, so in this research radon 222 concentration levels in water supplies in essentially the only source of Canadian uranium for nuclear power for the foreseeable future, and were the Canadian radon sources examined in this study . Soil is the main source of indoor radon; however, building materials and water supply can also be sources.
