New Forensic Dating Method Using Activity Ratio of Thorium and Radium

The activity ratio of 228Th to 228Ra in bone tissue from recently deceased humans presents a novel approach for determining time since death. Traditional methods for assessing the post-mortem interval often face methodological challenges. This new technique allows for a more reliable analysis by measuring the specific activity ratio of these isotopes, which can enhance forensic examinations. The study highlights the potential applications of this method in analyzing human skeletons or individual bones, providing crucial insights for forensic investigations.
