Difference between radiometric dating carbon 14 dating
Question: "Is carbon dating a reliable method for determining the age of things?
" Answer: 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.
Several factors affect radiocarbon test results, not all of which are easy to control objectively.
For this reason, it’s preferable to date objects using multiple methods, rather than relying on one single test.
Second, radiocarbon dating becomes more difficult, and less accurate, as the sample gets older.
If the spear head is dated using animal bones nearby, the accuracy of the results is entirely dependent on the assumed link between the spear head and the animal.
Radiocarbon dating can’t tell the difference between wood that was cut and immediately used for the spear, and wood that was cut years before being re-used for that purpose.Nor can it tell if a much older spearhead was attached to a brand-new shaft.
