Reconstruction of atmospheric concentrations and deposition of uranium and decay products released from the former uranium mill at Uravan, Colorado

Distribution of natural radionuclides in surface soils in the vicinity of abandoned uranium mines in Serbia

“…The uranium concentrations obtained in this study are similar to those reported for uranium mining and milling sites in Portugal (Carvalho et al 2007(Carvalho et al , 2009), Namibia (Oyedele et al 2010), and Brazil (Fernandes et al 2006). About ten-fold higher values have been reported for uranium mining areas in Kyrgyzstan (Vandenhove et al 2006) and Colorado, United States (Rood et al 2008). Uranium concentrations in soils collected in the vicinity of abandoned uranium mines in Spain (Blanco et al 2005) and Australia (Hancock et al 2006) were found to be about 30-fold higher than uranium concentrations obtained in this study.…”

Study of radioactive contamination in silts and aerosols at Aldama City, Mexico, due to the operation of a yellow-cake processing plant

“…These concentrations will also serve as boundary and initial conditions for the CALPUFF program, with which dispersion and deposition of radioactive particles produced during the extraction of uranium can be estimated (Rood et al, 2008). Other isotopes of cosmogenic, anthropogenic, and natural origin, such as 7 Be,137 Cs, and 40 K, respectively, were also included in the analysis.…”

The Impact of an Abandoned Uranium Mining Area on the Contamination of Agricultural Land in its Surroundings

“…This source of contamination is ranked among Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) sources reported in Carvalho et al (2007) and Rood et al (2008). The author pointed out that the tailing piles were sources that could not be entirely neglected.…”

“…The dust particles could be suspended mainly during a storing gangue on the piles and only in a small portion afterward (Rood et al 2008). Moreover, the crushing of ore could also contribute to contamination of the surroundings.…”
