Soil-to-cassava transfer of naturally occurring radionuclides from communities along Ghana's oil and gas rich Tano Basin
چکیده انگلیسی
Soil-to-plant transfer factor (TF) is widely used to assess the impact of soil radioactivity on agricultural crops. The root crop cassava (Manihot esculenta) provides 30%-50% of the calories consumed in Sub-Saharan Africa and is widely used in South America. γ-ray analysis was used to measure activity concentrations of 238U, 232Th, and 40K in cassava root and soil. The TF values for 238U, 232Th, and 40K were in the range 0.06-0.12, 0.01-0.10 and 0.04-0.28 respectively. The median transfer factors were 0.10 (238U), 0.04 (232Th) and 0.08 (40K). For 238U and 232Th, the highest TF values were 0.12 and 0.10 respectively.
