| Podsumowanie≠ | Radiocarbon dating is a radiometric technique that determines the age of organic materials by measuring the radioactive decay of ¹⁴C (carbon-14), a rare isotope produced in the atmosphere by cosmic ray interactions. Developed by Willard Libby in 1949, radiocarbon dating became a foundational method in archaeology, paleoclimate studies, and geology, enabling dating of organic materials from the past ~50,000 years with typical precision of ±50–100 years. | Isotope Ratio Mass Spectrometry (IRMS) is an analytical technique that measures the relative abundance of stable isotopes (H, C, N, O, S) and some radiogenic isotopes (e.g., ⁸⁷Sr/⁸⁶Sr) in samples with high precision. Standardized by Coplen and colleagues, IRMS enables paleoclimate reconstruction, source tracing (diet, water origin), geochemical fingerprinting, and age dating through radiogenic isotopes. |
