AI Article Synopsis
- Soil-to-plant transfer factor (TF) evaluates how soil radioactivity affects crops, focusing on the cassava plant, a major food source in Sub-Saharan Africa and South America.
- Measurement of uranium (U), thorium (Th), and potassium (K) concentrations in cassava roots and soil was conducted using γ-ray analysis.
- The results showed TF values ranging from 0.06-0.12 for U, 0.01-0.10 for Th, and 0.04-0.28 for K, with median values of 0.10, 0.04, and 0.08, respectively, indicating low transfer rates for these elements.
Article Abstract
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 U, Th, and K in cassava root and soil. The TF values for U, Th, and K 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 (U), 0.04 (Th) and 0.08 (K). For U and Th, the highest TF values were 0.12 and 0.10 respectively.
