Assessment of radionuclide concentration and exhalation studies in soil of lesser Himalayas of Jammu and Kashmir, India

Mathematical Modelling to estimate Radon exhalation rates: A study on soil samples from Pangi valley of Chamba district, Himachal Pradesh, India

“…On comparing, the value of radon exhalation rate obtained in the current study from soil samples are found to higher than those reported in some areas of Bharmour and Tisa province of Himachal Pradesh Jammu and Kashmir by[31] and Hamirpur district of Himachal Pradesh by[32] but are lower than those reported in Egypt by[33], presented in table 3. The main reason for the high radon exhalation rate in soil samples of the study area is, the presence of uranium and radium bearing parent rock and their interaction with the soil.…”

Measurement of natural radioactivity and radiological hazard evaluation in the soil samples collected from Owo, Ondo State, Nigeria

“…Such studies have provided reference data to compare the possible change of environmental radioactivity resulting from anthropogenic activities now or in the future. Several studies on soil radioactivity have been reported from different parts of the world (Chinnaesakki et al, 2011;Issa, 2013;Kritsananuwat, Arae, Fukushi, Sahoo, & Chanyotha, 2015;Kumar, Vij, Sharma, Sarin, & Narang, 2018;Mohammed & Ahmed, 2017;Oyeyemi, Usikalu, Aizebeokhai, Achuka, & Jonathan, 2017;Raghu, Ravisankar, Chandrasekaran, Vijayagopal, & Venkatraman, 2016;Sahin & Cavas, 2008;Sivakumar, 2014;Zaim & Atlas, 2016) with the sole aim of assessing the radiological health impact on the human population and to enrich the global data bank, which can enhance knowledge of radiation effects even at low levels of exposures. This study was aimed at determining the activity concentrations of radionuclides ( 40 K, 226 Ra, and 232 Th) in the subsurface soils of Owo Local Government Area (OLGA) of Ondo state, Nigeria.…”
