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.
In Europe, the European Commission enforced that from 2015 all new cars registered shall not emit more than an average of 0.13 kg (0.29 lb) of CO 2 per kilometre (kg CO 2 /km). The target is that by 2021 the average emissions for all new cars is 0.095 kg (0.21 lb) of CO 2 per kilometre.
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, [6] 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 ...
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 ...
The series utilizes the 2.0L powerplant of the new Mazda MZR engine or an older Zetec or Pinto engine coupled with chassis from companies such as Van Diemen, Citation, Mygale, RFR, Radon and Piper. Unlike other developmental series, there are no spec cars in F2000. The series has existed in one form or another since the 1970s.
The Buc-ee’s location sixty miles north of Atlanta near Calhoun, Ga. sometimes sees lines of cars that stretch a mile, according to Bloomberg. The gas station chain has also gone viral for its ...
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]
