Radon and its daughters are, taken together, often the single largest contributor to an individual's background radiation dose, but due to local differences in geology, [5] the level of exposure to radon gas differs by location. A common source of environmental radon is uranium-containing minerals in the ground; it therefore accumulates in ...
Radon is responsible for the majority of public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as attics and basements.
The gamma spectrum shows prominent peaks at 609, 1120, and 1764 keV, belonging to bismuth-214, a radon decay product. The atmospheric background varies greatly with wind direction and meteorological conditions. Radon also can be released from the ground in bursts and then form "radon clouds" capable of traveling tens of kilometers. [7]
Exposure to radon gas is the second-leading cause of lung cancer in the United States and the leading cause of lung cancer among non-smokers. January is National Radon Action Month Skip to main ...
Residues from the oil and gas industry often contain radium and its daughters. The sulfate scale from an oil well can be very radium rich. The water inside an oil field is often very rich in strontium, barium and radium, while seawater is very rich in sulfate: so if water from an oil well is discharged into the sea or mixed with seawater, the radium is likely to be brought out of solution by ...
