Radon 222 sources

This isotope of radon belongs to the radioactive lineage of uranium 238, and is its sixth generation descendant. It is formed by the decay of its precursor, radium-226. It decays within a few days into polonium 218 through the emission of an alpha particle. 222 Rn concentration levels in different sources of the water were measured using a portable pulse-counting ionization chamber (alpha spectroscopy), AlphaGUARD (SAPHYMO GmbH). The AED due to ingestion and inhalation of radon in the water samples were determined. Radon (222 Rn) is released primarily from soil and approximately 10% of it is released into the atmosphere (3, 4). 218 Po, 214 Pb, and 214 Bi are radon’s most significant progeny in terms of radiation dose.

Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56-98.57, 0.88-25.49, 0.73-1.35 and 0.24-1.03 Bq.L-1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% 2020-08-16 2018-03-05 Radon 222 is the mais source of natural radioactivity to which humans are exposed. This isotope of radon belongs to the radioactive lineage of uranium 238, and is its sixth generation descendant.

Cohen, Alan Griffiths, Alastair Williams, Eduard Stelcer Australian Nuclear Science and Technology Organisation, Locked Bag 2001 Kirrawee DC NSW 2232, Australia ABSTRACT Studies have shown that Radon-222 (222Rn) and its progeny contribute about 50% of the total effective dose equivalent from natural sources.
