Short notes on radiocarbon dating
Any carbon-containing material that affects the carbon 14 content of any given sample is therefore a contaminant.Important Note on Pretreatment – It is important to understand the pretreatments which are going to be applied to samples since they directly affect the final result.Radio carbon dating is a technique of finding out the age of organic matters like fossils, wood, leather etc.by comparing the amount of radio carbon present in them.There is no standard method for pretreatment applicable to all samples for radiocarbon dating.The pretreatment method employed depends on the type of sample and the possible contaminants.
Another example of a natural contaminant is plant root penetration on wood, charcoal, or soil.You are welcome to contact us to discuss the pretreatment or request that we contact you after the pretreatment (and prior to dating).Materials such as charcoal, wood, peat, and textiles typically undergo the acid-alkali-acid (AAA) method before radiocarbon dating.When roots of plants penetrate wood, charcoal, soil, or bones, modern carbon is already introduced to them.This occurrence can make the samples seem younger than their true age.
