Carbon Dating – carbon-14
{"Image DocumentName": "Carbon Dating \u2013 carbon-14", "Image ImageDescription": "Living things replace the carbon-12 and carbon-14 in their bodies when they are alive. However when living things die, they do not replace the carbon-14 as carbon-14 decays into nitrogen-14. Carbon-14 takes 5715 years to decay half of its nuclei into nitrogen- 14. Carbon-12 remains unchanged. Therefore something that has been alive within the past years contains enough nuclei of remaining carbon-14 to measure. The ratio of carbon-12 and carbon-14 can estimate the age of the sample.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
