“…The indoor f p varies from 9.3 to 16.9%, with typical values of 10.9 and 12.8% for urban and rural indoor environments, respectively. The f p values in indoor environments are quite similar to the results of Canoba's measurements in dwellings without additional aerosol sources in Argentina (f p : 9%-29%) [21] and also Tokonami's continuous measurement results in dwellings with air circulating systems in Japan (f p : 11%) [22], a little larger than Reineking's measurement results (f p : 9%) in Germany [23] and El-Hussein's results for indoor air in the cellar of the Physics Department of El-Minia University, Egypt (f p : 6 ± 0.5%) [24] as well as Chen's survey results in 14 dwellings in Kaohsiung, Taiwan (f p average 5.5%, from 2.7 to 13.1%) [25], but much smaller than Huet's 1-year measurement in an old dwelling situated in Brittany (f p average 31%, from 8 to 67%) [26]. These differences are mainly a result of differing environmental factors, especially the aerosol concentration and ventilation rate.…”

Assessment of the unattached fraction of indoor radon progeny and its contribution to dose: a pilot study in China

The unattached fraction of radon progeny (f(p)) is one of the most important factors for accurate evaluation of the effective dose from a unit of radon exposure, and it may vary greatly in different environments. For precise evaluation of the indoor radon exposure dose and the influence of unattached radon progeny, a pilot survey of f(p) in different environments was carried out in China with a portable and integrating monitor. The dose conversion factors for radon progeny are calculated with LUDEP(®) code, and the dose contributions from the unattached and the attached radon progenies were simultaneously evaluated based on the results of field measurements. The results show that even though the concentrations of radon progeny vary significantly among different indoor environments, the variations of f(p) seem relatively small (9.3-16.9%). The dose contribution from unattached radon progeny is generally larger (30.2-46.2%) in an indoor environment.

“…The average of f p indoors is 8.7%, and the minimum is 6.3% which appears in June, while the maximum is 12.5% which appears in February. The average value is quite similar to Reineking's measurement results ( f p : 9%) in Germany [13], a little larger than El-Hussein's results in the cellar of the Physics Department of El-Minia University, Egypt ( f p : 6 ± 0.5%) [13] and Chen's survey results in 14 dwellings in Kaohsiung, Taiwan ( f p average 5.5%, from 2.7 to 13.1%) [14], a little smaller than Canoba's measurements in Argentina (f p : 9%-29%) [15] and Tokonami's results with air circulating systems in Japan ( f p : 11%) [16].…”

The unattached fraction of radon progeny is one of the most important factors for radon exposure evaluation through the dosimetric approach. To better understand its level and variation in the real environment, a series of field measurements were carried out indoors and outdoors, and radon equilibrium equivalent concentration was also measured. The dose contribution of unattached radon progeny was evaluated in addition. The results show that no clear variation trend of the unattached fraction of radon progeny is observed in an indoor or outdoor environment. The average unattached fraction of radon progeny for the indoors and outdoors are (8.7 ± 1.6)% and (9.7 ± 2.1)%, respectively. The dose contribution of unattached radon progeny to total radon exposure is some 38.8% in an indoor environment, suggesting the importance of the evaluation on unattached radon progeny.

“…UNSCEAR reports provide a synopsis of the radon survey in many countries around the world [2,4]. In African countries, radon was measured in different countries Ethiopia [38], Uganda, Kenya [39], Ghana [40] and Latin American countries [41]. On the other hand, radon measurement was conducted in some Arab countries through under research program supported by the Arab Atomic Energy Agency [42].…”

The goal of this work is to build up a national database for radon in houses, soil, and water and to demonstrate health risk due to radon inhalation and to construct radon map in the country in order to provide the scientific basic information for the establishment of radon national standard level. The radon predictive maps were built employing familiar GIS software (ArcView 3.2). The review outcomes highlight the characteristics and behaviour of radon in the environment as well as the importance of legislation making radon monitoring in the country is compulsory. If the outcome of this review is hoped that will increase regulation awareness and culture to deal with radon level in Sudan.
