← ScienceWhich mechanism causes carbon-14 dating inaccuracies in specimens?
A)Variable atmospheric isotope production✓
B)Consistent radioactive element decay
C)Geiger counter equipment drift
D)Stable isotope cross contamination
💡 Explanation
Variable atmospheric isotope production alters the assumed initial carbon-14 concentration. As the rate of carbon-14 creation, via cosmic ray impacts, fluctuates over time, therefore the calculated dates are incorrect rather than consistently under or overestimated with a reliable standard.
