    Long-term exposure to high radon levels can increase the risk of developing lung cancer. In fact, radon is the second leading cause of lung cancer in Idaho, according to the health department.

    An open-land test kit can test radon emissions from the land before construction begins. A Lucas cell is one type of long-term device. A Lucas cell is also an active device, or one that requires power to function. Active devices provide continuous monitoring, and some can report on the variation of radon and interference within the testing period.

    Radon can be oxidized by powerful oxidizing agents such as fluorine, thus forming radon difluoride (RnF 2). [24] It decomposes back to its elements at a temperature of above 523 K (250 °C; 482 °F), and is reduced by water to radon gas and hydrogen fluoride: it may also be reduced back to its elements by hydrogen gas. [25]

    A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.

    In a working mine, the radon level can be controlled by ventilation, sealing off old workings and controlling the water in the mine. The level in a mine can go up when a mine is abandoned; it can reach a level which can cause the skin to become red (a mild radiation burn). The radon levels in some of the mines can reach 400 to 700 kBq m −3. [17]

    Radon gas in the natural gas streams concentrate as NORM in gas processing activities. Radon decays to lead-210, then to bismuth-210, polonium-210 and stabilizes with lead-206. Radon decay elements occur as a shiny film on the inner surface of inlet lines, treating units, pumps and valves associated with propylene, ethane and propane processing ...

    en.wikipedia.org/wiki/Radon_compounds

    Radon compounds are chemical compounds formed by the element radon (Rn). Radon is a noble gas, i.e. a zero-valence element, and is chemically not very reactive. The 3.8-day half-life of radon-222 makes it useful in physical sciences as a natural tracer. Because radon is a gas under normal circumstances, and its decay-chain parents are not, it ...

    Alternatively, radon may enter the body through contaminated drinking water or through the decay of ingested radium [3] – making radon diffusion one of the greatest dangers of radium. [10] Thus, 222 Rn is a carcinogen ; in fact, it is the second leading cause of lung cancer in the United States after cigarette smoking , [ 3 ] with over 20,000 ...
