The most popular method of radio dating is radio carbon dating which is possible because of the presence of C, an unstable isotope of carbon.

The modern science of dendrochronology was pioneered by A. If the specimen is analyzed after having been exposed to contamination by carbon compounds of an age younger than its own, radio carbon age is liable to be reduced.
