Examples of Radon progeny in a sentence

  • Radon progeny, which are much more abundant than thoron progeny in most areas, decay with an effective half-life of about 30 minutes and a counting delay of 3 hours may be adequate.

  • Radon contractor" or "contractor" means a person licensed to perform radon or radon progeny mitigation or to perform measurements of radon or radon progeny in an indoor atmosphere.(j) "Radon progeny" means any combination of the radioactive decay products of radon.

  • Radon progeny and medical diagnostic or therapeutic procedures involving radionuclides can cause interferences to in vivo measurements, especially for NaI detectors.However, unless the count was invalidated or noted as being influenced by such interferences, the results should be used as recorded.

  • This shows that in this subsector there are mostly small workshops and enterprises with very few employees.

  • Radon progeny, another respirable radiation hazard, was also a source of internal exposure in certain areas of the plants.The subsections below summarize the extent and limitations of information available for reconstructing the internal doses of members of the class.

  • Radon progeny, however, are charged and electrostatically attach themselves to inhalable aerosol particulates, which are deposited in the lung or directly onto lung tissue.

  • Radon progeny as a tool in the assessment of particle surface area.As discussed above, one very important property of radon decay is that after radon decay, the newly formed atom of Po forms clusters that are useful as markers in studies of properties of non-radioactive aerosols.

  • But only in the beginning of the 1950ties it could be demonstrated that the Radon progeny in deep mines cause extremely high radiation exposures of the lung which are the cause of the lung cancers (BALE 1951).

  • Normally, the dose assessment for radon is based on the following three approaches: • Radon progeny measurements; • Radon gas measurements; • Radon exposure (activity concentration during a specified period of time).

  • Radon progeny concentrations are commonly expressed in working levels (WL).One WL is defined as any combination of short-lived radon daughters in 1 liter of air that results in the ultimate release of 1.3×105 million electron volts of alpha energy.
