Radioactive Carbon Dating
Radioactive carbon dating, a cornerstone technique in archaeology and geology, provides invaluable insights into the age of organic materials. By measuring the decay of carbon-14 isotopes present in once-living organisms, scientists can estimate the age of artifacts and geological samples with remarkable precision. This method relies on the principle of radioactive decay, where carbon-14 gradually transforms into nitrogen-14 over time. Through meticulous analysis of carbon-14 levels in samples, researchers can unravel the chronological timelines of past civilizations, geological formations, and evolutionary processes. Radioactive carbon dating stands as a testament to the intersection of physics, chemistry, and archaeology in unraveling the mysteries of the past.
