Radiocarbon dating tools

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

Different cultures around the world record time in different fashions.

With carbon dating the type of sample and the placement of it within the site are very important.

Some samples might be degraded or out of context within the site: meaning a spurious date might be assigned.

And samples must be collected carefully, as often they have been in stable environments prior to their unearthing by industrious archaeologists and may be easily degraded in the open air or attacked by moisture and sunlight once gathered.

Old school radiocarbon dates used to be collected using Geiger counters to establish the amount of radiation they were emitting.

And also, rather importantly, the laws of radioactive decay hypothesize that once a living organism is dead, it no longer interacts with anything in its environment which would affect the speed of its radioactive decay.

­ ­You probably have seen or read news stories about fascinating ancient artifacts. Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.And if the artifact is organic—like wood or bone—researchers can turn to a method called radiocarbon dating.When that organism dies, the carbon fourteen decays at a known exponential rate: making it possible to calculate the approximate time when the organism died based on how much carbon fourteen remains in a sample of the dead material.It can date a variety of materials, ranging from, but not necessarily limited to: bone, shell, charcoal, soft tissue, horn, teeth, ivory, hair, blood, wool, silk, leather, paper, parchment, insects, coral, metal if there is charcoal present in it, and sometimes dirt.
