Applications De Recherche Scientifique
Radiometric Dating
Geological and Archaeological Applications
One of the primary applications of is in radiometric dating, especially for geological and archaeological samples that are older than what conventional carbon dating can handle. The isotope is produced through cosmic-ray interactions with calcium in terrestrial materials. Researchers have developed methods to measure concentrations in samples such as granite, seawater, and bone using advanced techniques like accelerator mass spectrometry (AMS) .
Case Study: Dating Pleistocene Bones
A study focused on the use of for dating Middle and Late Pleistocene bones demonstrated its effectiveness. The concentrations measured were between and for contemporary bovine bone samples, indicating the potential for dating remains that are tens of thousands to millions of years old . This capability is particularly useful for dating specimens that have been buried under ice or sediment, where traditional dating methods may fail.
Environmental Monitoring
Assessment of Geological Processes
Another significant application of is in environmental monitoring, particularly in assessing geological processes. The isotope can be used to study the movement of groundwater and the transport of contaminants through geological formations. By measuring the ratio in various samples, researchers can gain insights into historical changes in environmental conditions .
Medical Applications
Monitoring Bone Health
In the medical field, serves as a powerful tracer for monitoring bone metabolism and assessing bone diseases. A pharmacokinetic model has been developed to evaluate its feasibility in clinical settings. This model allows for the monitoring of calcium balance in patients undergoing treatment for conditions like osteoporosis .
Case Study: Clinical Trials for Osteoporosis Treatment
Research conducted at Purdue University utilized to assess the efficacy of various treatments aimed at preventing bone loss. By measuring the ratio in urine, researchers could quantify changes in net bone turnover over time. This method offers greater precision than traditional biochemical markers and can track responses to therapy over extended periods .
