Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.Contaminants must not be introduced to the samples during collection and storing.Hydrocarbons, glue, biocides, polyethylene glycol, or polyvinylacetate must not come in contact with samples for radiocarbon dating.The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.When a living thing dies, it stops interacting with the biosphere, and the carbon 14 in it remains unaffected by the biosphere but will naturally undergo decay.Other potential contaminants include paper, cardboard, cotton wool, string, and cigarette ash.

Samples must be stored in packaging materials that will protect them during transport and even during prolonged storage.

Before deciding on using carbon dating as an analytical method, an archaeologist must first make sure that the results of radiocarbon dating after calibration can provide the needed answers to the archaeological questions asked.

The implication of what is represented by the carbon 14 activity of a sample must be considered.

It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.

Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.

Labels attached to the packaging materials must not fade or rub off easily.
