If the decay constant (λ) is large, the half-life is small, and vice versa. The Carbon-14 Cycle. However, radiocarbon dating—the most common chronometric technique in archaeological and palaeoenvironmental research—creates challenges for established statistical methods. Table 1. 109 accounts for the fact that only 10. I'm thinking about getting back into dating. Carbon has two stable, nonradioactive isotopes: carbon-12 (12 C) and carbon-13 (13 C). It uses the naturally occurring radioisotope carbon-14 (14 C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old.
