“…In Sudan some few efforts have been made to measure radon in air, soils, building materials, and water [13][14][15][16][17][18][19]. Numerous nationwide radon studies were conducted in European countries [20][21][22][23][24][25][26][27][28][29][30][31], [32]. and in the US [33][34][35].…”

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.

“…Radon is the most important source of radiation hazard for people (WHO 2009;Barnet 2012;Killmer 2004). The properties of radon allow it to enter and accumulate in confined spaces, like e.g.…”

“…The radon production depends on the material's porosity, radium concentration and the diffusion coefficient. Many results of experimental researches have been reported for radon transport in soil (Barnet 2012;Prasad et al 2013;Van der Pal et al 2001). Another possible approach is the modelling of radon transport; it has been done for instance by Sasaki et al (2006), Savovic and Djordjevich (2008) and Urosevic and Nikezic (2003) using various media like soil, water, air, etc.…”

The main goal of the research presented was to design and construct a device, enables estimation of the diffusion time and diffusion length for radon in core samples collected from the geological layers of Upper Silesian Coal Basin (USCB). Another goal will be investigations of the advection of 222 Rn with other gases like carbon dioxide or methane, occurring in the Carboniferous strata in USCB. This knowledge will support the precision of the assessment of radon hazard in working environment. Moreover, it should give an answer to some questions, related to the radon migration issues-if the results of measurements of the transport of radon with other gases in the strata could be applied for the prediction of geodynamic phenomena in the mining areas, like tremors and outbursts. The study was focused on the flow measurements of the following gases: radon, carbon dioxide, nitrogen and their mixtures, as the use of methane was excluded due to potential hazard of explosion. In this article results of measurements of diffusive migration are presented: radon itself and simultaneous migration of radon, nitrogen and carbon dioxide. For this purpose a special device was designed and constructed. This device consists of the container for the sample of coal, mineral or rock and two reservoirs-the inlet and outlet one. The gas (e.g. air or carbon dioxide) with radon is introduced into inlet reservoir, while the content of marker gases and radon is monitored in the outlet reservoir. The preliminary experiments were also performed and are presented in this paper. In the literature, there are only rare results of such investigations, while our previous research in USCB region showed some correlation between sudden changes of radon level and geodynamic events. Therefore, the results of the investigations presented in this study are expected to contribute to the improvement of the models of these phenomena. The future work planned will be aimed at investigations of advective flow of radon with various carrier gases.

“…Approaches to radon hazard assessment have included direct measurements of indoor radon (Dubois, 2005), soil gas measurements (Kemski et al, 2001;Dubois, 2005;Barnet, 2011;Cinelli et al, 2015), chemical analysis of bedrock and soils (Ielsch et al, 2010;Drolet et al, 2013), and airborne eU (equivalent uranium) measurements (Åkerblom, 1995;Ford et al, 2001;IAEA, 2003;Smethurst et al, 2008;Drolet et al, 2013). Many studies have investigated relationships between geology and indoor radon (e.g.…”
