Other labs accept waterlogged wood while others prefer them dry at submission.2.

Sample collection Contaminants must not be introduced to the samples during collection and storing.

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.

Decay of carbon 14 takes thousands of years, and it is this wonder of nature that forms the basis of radiocarbon dating and made this carbon 14 analysis a powerful tool in revealing the past.

But archaeology’s aim to understand mankind is a noble endeavor that goes beyond uncovering buried treasures, gathering information, and dating events.

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.

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.

It is important that the radiocarbon scientists and archaeologists agree on the sampling strategy before starting the excavation so time, effort, and resources will not be wasted and meaningful result will be produced after the carbon dating process.Historians can tell what cultures thrived in different regions and when they disintegrated.Anthropologists can describe a people’s physical character, culture, and environmental and social relations.Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists.The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.Sample storage Samples must be stored in packaging materials that will protect them during transport and even during prolonged storage.
