Beach sand can contain natural radioactivity from naturally occurring radioactive materials (NORMs) like uranium (238U), thorium (232Th), and potassium (40K). These materials can come from metamorphic and magmatic rocks that break down over time through weathering and erosion to form beach sand. The concentration of these materials can vary, and sands with smaller grains tend to have higher levels of activity
