Factors that can affect the utility of radiocarbon dating include:
A) contamination (e.g., by coal).
B) atmospheric fluctuations of 14C.
C) the length of time wood is useful after it dies ("old wood" problem).
D) All of the answers are correct.

Question

Quizplus · Accepted Answer

All the listed factors can affect the accuracy of radiocarbon dating. Contamination by materials like coal can introduce carbon of a different age into a sample. Atmospheric fluctuations of 14C over time can alter the baseline levels of 14C assumed in calculations. The "old wood" problem refers to the potential for wood to have been used long after it died, leading to inaccuracies if the wood's death rather than its use is dated.
