Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.

ICA opened its doors in to help satisfy the growing need for affordable radiocarbon dating analysis with a fast turn-around. Since opening, ICA has dated thousands of carbon samples for hundreds of clients from all over the world. We understand that in radiocarbon dating, each sample is unique. For this reason, ICA treats each one of your samples with special care to determine the best applicable protocol. ICA offers an unique combination of affordability, quality, and fast turnaround that is unmatched.

Just like a teenager wanting to be older, volcanoes can lie about their age, or at least about their activities. For kids, it might be little white lies, but volcanoes can tell big lies with big consequences. Our research , published today in Nature Communications, uncovers one such volcanic lie.
A small-necked bottle will generally seal better than a large-necked bottle but either is acceptable. We accept no responsibility for the accuracy of testing results for samples submitted in collection bottles other than those specified. The samples must not be stored or handled in any laboratory or area that uses OR has ever used biomedical or artificially labeled 14C at any time. Water samples that produce activities above pMC will incur extensive costs related to any cleanup necessary, equipment replacement and duplicate analyses required for other samples.
