WebThis method of radiometric dating, which is also called radiocarbon dating or carbon-14 dating, is accurate for dating carbon-containing substances that are up to about 30,000 years old, and can provide reasonably accurate dates up … WebCan carbon dating be used on human fossil older than 50,000 years? No, for two reasons. First, the half-life of decay for C14 is 5,730 years which limits its utility to dating samples no more than about 50K years. Beyond that time period there is insufficient C14 remaining in the sample to be accurately quantified.
