However, if the bone is 70, years or older the amount of 14 C left in the bone will be too small to measure accurately. Measurement of radiocarbon was originally done with beta-counting devices, which counted the amount of beta radiation emitted by decaying 14 C atoms in a sample. Evacuation plan from Afghanistan. In this case, fossils can be useful tools for understanding the relative ages of rocks. Because organisms restock their C supplies continuously, the ratio of carbon isotopes they contain at the time of their death can be assumed to be the same as the corresponding ratio in the atmosphere during their lifetime. S2CID These improved field methods were sometimes motivated by attempts to prove that a 14 C date was incorrect.
