Is it true that radiocarbon dating is limited to approximately forty to fifty thousand years due to the half-life of carbon-14?
Yes. Radiocarbon dating has a practical limit of roughly 40,000 to 50,000 years, determined by the half-life and progressive decay of carbon-14.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The analysis
The claim is a specific, well-established empirical fact regarding the methodological limits of radiocarbon dating based on radioactive decay. Papers 1 and 2 directly support the dating limit of around 45,000 to 50,000 years and discuss the underlying nuclear half-life. No papers refute the claim.
