Why is the carbon-14 dating not accurate for estimating the age of materials more than 50,000 years old?
A)This form of radioactive dating is only accurate back 1400 years.
B)The concentration of carbon-14 in a body after 50,000 years is too low.
C)Living organisms are too decomposed after 50,000 years.
D)Actually,carbon-14 dating is accurate back to around 5 million years ago.

Question

Quizplus · Accepted Answer

The half-life of carbon-14 is approximately 5,700 years. This means that after 50,000 years, the concentration of carbon-14 in a sample is too low to accurately measure. At this point, there is only a tiny fraction of the original carbon-14 remaining in the sample, making it difficult to distinguish from the background radiation.
