Abstract:The activities of the naturally occurring radionuclides 232Th, 226Ra, 40K and 238U of the shore sediments in the South Gondar Zone were determined and used to evaluate radiation hazards in the study spots. The activities of 232Th, 226Ra, 40K and 238U range from 46 to 179, 62 to 140, 125 to 449 and 72–156 Bq/kg, with the overall average of 123.07 ± 7.90, 105.34 ± 4.27, 371.38 ± 13.53 and 115.52 ± 4.62 Bq/kg, respectively. These were analogous to concentrations of other states in worldwide. We recommend to all t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
