Question
Chapter 11, Problem 11.4CTE
Interpretation Introduction
Interpretation: We have to evaluate the claim whether the scientific report explaining the age of an artifact to be 80,000 years old, is valid or invalid.
Concept introduction: Carbon-14 dating is a method used to determine the age of an archeological organic sample up to about 60,000 years old. C-14, that accumulates in the organic matter is radioactive and decays into nitrogen-14, with a half life of about 5730 years. It will take about 60,000 years for the C-14 present in a dead sample to decay completely.
