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.

Glass containers can be used when storing radiocarbon dating samples, but they are susceptible to breakage and can be impractical when dealing with large samples.

The sample-context relationship is not always straightforward.

Date of a sample pre-dates the context it is found.

Great care must be exercised when linking an event with the context and the context with the sample to be processed by radiocarbon dating.

An archaeologist must also make sure that only the useful series of samples are collected and processed for carbon dating and not every organic material found in the excavation site.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.Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology.Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists.Other potential contaminants include paper, cardboard, cotton wool, string and cigarette ash.3.
