Description
An ancient bone age determination method with high sensitivity has been introduced, based on evaluating the specific activity of 226Ra. This technique involves detecting alpha emissions from 222Rn through the use of a CR-39 track detector in an isolated chamber. When comparing the specific activity of 226Ra in the bones of Archanthropus, southern mammoths, and dinosaurs with standard bone samples, a direct correlation was observed between the bones age and specific activity of 226Ra in these bones. Additionally, the study includes data on the specific activity of 226Ra in soil samples collected from the excavation sites where these fossils were discovered.
