Spatial and temporal analysis of the sedimentary record of 238U and 232Th series in seven major French rivers: the role of geology and NORM occurrence

Key Points

• Key patterns in the sedimentary record of uranium and thorium were identified across various locations with different geological contexts.
• The analysis examined seven major French rivers, uncovering variations in the 238U and 232Th series based on geological factors.
• Investigative assessment utilized both spatial and temporal analysis methods, linking geology to the occurrence of naturally occurring radioactive materials.
• Understanding these sedimentary dynamics may inform environmental monitoring and risk assessment concerning NORM in river systems.
