Humans ingest approximately 1-5 mg of strontium everyday! An interesting video describes how scientists use the element strontium to learn about people. The narrator explains where strontium is found and how it gets into and builds up in the human body. Through the analysis of strontium in teeth, anthropologists can tell where ancient peoples were born and grew up.
