The reason for the carbon-14 dating not accurate for estimating the age of materials more than 50000 years old.
Answer to Problem 15RQ
The only trace amount of carbon-14 would be left after
Explanation of Solution
The half-life of the carbon-14 is
The radioactive decay rate is the numerical average of a large number of decaying atoms and the short life of the carbon-14 would be left after the 50000 years, which is too small to be accurate numerically.
Conclusion:
Therefore, the only trace amount of carbon-14 would be left after
