What Does PMC Stand For?

PMC stands for Percent Modern Carbon

Percent Modern Carbon (PMC) is a measurement used in radiocarbon dating to express the ratio of radiocarbon content in a sample compared to the baseline level of atmospheric carbon during the modern era. It is typically expressed as a percentage, indicating how much of the carbon in a sample is derived from contemporary sources as opposed to older, fossilized carbon. PMC values are crucial for understanding the age and authenticity of carbon-containing materials in various fields such as archaeology, geology, and environmental science.
