Soil-to-rice transfer factors of naturally occurring radionuclides in the Afram Plains, Ghana, and their potential radiological risks.
This study investigated the transfer of soil-based natural radionuclides from soil to rice in the Afram Plains and the potential radiological health risk to consumers. Gamma spectrometry was employed to measure activity concentrations of radionuclides in soil and rice samples. Transfer factors (TFs) estimated from the concentrations of U-238, Th-232, and K-40 were above the International Atomic Energy Agency values for TFs. Annual effective dose and excess lifetime cancer risk from rice consumption were below UNSCEAR and global average permissible levels, indicating minimal radiological risk. However, the study recommended strategies to reduce activities that could increase radionuclide concentrations in the future to reduce the potential health risks associated with rice consumption in the study area.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
