Radiocarbon dating biology definition

For decades after Libby performed the first radiocarbon dating experiments, the only way to measure the 14 C in a sample was to detect the radioactive decay of individual carbon atoms. The sequence can be compared to the calibration curve and the best match to the sequence established.

What is Carbon Dating? - Definition & Overview

Help and Review College Chemistry: It can be cited as: Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14 C atoms in a sample. The enrichment of bone 13 C also implies that excreted material is depleted in 13 C relative to the diet. At higher temperatures, CO 2 has poor solubility in water, which means there is less CO 2 available for the photosynthetic reactions.
