Does carbon dating work

For this reason, it’s preferable to date objects using multiple methods, rather than relying on one single test.

Carbon dating is reliable within certain parameters but certainly not infallible.

After about 10 half-lives, the amount of radiocarbon left becomes too miniscule to measure and so this technique isn't useful for dating specimens which died more than 60,000 years ago.

We also know that the ratio decreased during the industrial revolution due to the dramatic increase of CO produced by factories.

When testing an object using radiocarbon dating, several factors have to be considered:, and it only determines the approximate date of death for that sample.

For example, a steel spearhead cannot be carbon dated, so archaeologists might perform testing on the wooden shaft it was attached to.

C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).

The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous.

Carbon dating, or radiocarbon dating, like any other laboratory testing technique, can be extremely reliable, so long as all of the variables involved are controlled and understood.
