Environmental evaluation of natural radioactivity in soil near a lignite-burning power plant in Turkey

Primordial radionuclides in the dust samples from the educational institutions of central Bangladesh: radiological risk assessment

“…Similarly, all the determined primordial radionuclides of this study represented similar trend as the surface soil samples of different countries in the subcontinent ( Mishra, 2004 ; Matiullah et al., 2004 ; Mandal and Sengupta, 2005 ; Fatima et al., 2007 ; Prasad et al., 2008 ; Shanthi et al., 2010 ; Badhan and Mehra, 2012 ; Babai et al., 2013 ; Dhawal et al., 2013 ; Sahoo et al., 2016 ; Pillai et al., 2017 ; Bramha et al., 2018 ). Herein, 226 Ra activities are greater than 232 Th in the dust samples of this work which is concomitant with the world literature values ( Bem et al., 2002 ; Papp et al., 2002 ; Faghihi et al., 2011 ; Flues et al., 2002 ; Dai et al., 2022 ; Amin et al., 2008 ; Arogunjo et al., 2009 ; Karamanis et al., 2009 ; Ribeiro et al., 2010 ; Otansev et al., 2012 ; Tufan and Bostanci, 2012 ; Amin et al., 2013 ; Charro et al., 2013 ; Papaefthymiou et al., 2013 ; Cujic et al., 2015 ; El-Mekawy et al., 2015 ; Liu et al., 2015 ; Alzubaidi et al., 2016 ; Goren et al., 2017 ; Zhang, 2017 ) while median n=23 value of 40 K activity in this study was relatively greater than the global median value. Hence, the variation of 40 K activities generated from differential geochemical settings while the discrepancy of 226 Ra activity concentrations between the classroom-dusts of this work and the surface soils n=45 ( Table 4 ) assumed to be derived from natural or/and the non-natural processes.…”

Impacts of coal-fired power plants for energy generation on environment and future implications of energy policy for Turkey

“…Radionuclides with differing intensities observed in various regions where CFPPs operated such as Kangal (Turhan 2020 ), Afşin-Elbistan (Cevik et al 2008 ; Çayır et al 2012 ), Yatağan (Baba 2002 ; Kursun et al 2016 ), and Soma (Kursun and Terzi 2016 ). On the contrary, Gören et al ( 2017 ) reported that despite the fly ash being more enriched with radionuclides, no significant radiation was observed in the Kangal CFPP vicinity. The authors stated that emission control systems that were utilized were effective in the prevention of the spreading of radionuclides.…”

Environmental Impacts of Coal-Mining and Coal-Fired Power-Plant Activities in a Developing Country with Global Context

“…Pollutants are released from CTP in different form and stages of the processing system, i.e., before (coal storage, processing), during combustion (flue gas), and after combustion processes and CCRs deposition, transportation, and utilization to the ambient environments as in the form of the gaseous phase, solid, and liquid discharges (Dai et al 2007(Dai et al , 2008(Dai et al , 2012(Dai et al , 2014aDragović et al 2013;Mahur et al 2013;Saikia et al 2014Saikia et al , 2015aSaikia et al , b, 2016Karamanis et al 2009). Some studies working on the NORMs contamination due to the coal-burning appeal for a trivial influence of radioactivity originated from CCRs on the soil environment (e.g., Habib et al 2019b;Papaefthymiou et al 2013;Charro and Pena 2013;Rosner et al 1984), whereas other studies (e.g., Gören et al 2017;Parial et al 2016;Liu et al 2015;Mandal and Sengupta 2006;Ćujić et al 2015Flues et al 2002;Amin et al 2013;Gür and Yaprak 2010;Lu et al 2012aLu et al , b, 2013Dai et al 2007;Bem et al 2002;Papp et al 2002) have demonstrated that a significant augmentation of NORM's content in the soil around CTP, mostly owing to the higher abundance of 238 U and 226 Ra in feed coals and associated CCRs (Table 24.10). However, it is essential to determine the level of NORMs and associated impacts on the ambient environment and on human health around CTPs.…”
