Accurate carbon dating

Contamination and repeatability are also factors that have to be considered with carbon dating.A tiny amount of carbon contamination will greatly skew test results, so sample preparation is critical.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.Modern effects such as fossil fuel burning and nuclear testing have also changed atmospheric carbon-14 levels and in turn change the “starting point” for a radiocarbon test.

When testing an object using radiocarbon dating, several factors have to be considered: First, carbon dating only works on matter that was once alive, and it only determines the approximate date of death for that sample.

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.

When an organism dies, it stops taking in new carbon-14, and whatever is inside gradually decays into other elements.

Carbon-14 normally makes up about 1 trillionth (1/1,000,000,000,000) of the earth’s atmosphere.
