Archaeological dating radioisotopes
To locate a leak in an underground pipe a very small amount of radioactive material that gives off gamma rays is put into the pipe.
A detector is moved along the ground above the pipe.
The post-biblical chronology from Jesus to the present day is also easily available from European historical record.
How do scientists know how old an object or human remains are?
Biblical chronology is the order and timing of events recorded in the Old Testament and New Testament.
The Bible is remarkably detailed in its chronology, giving precise dates and years for many important events and Biblical genealogies, for the events spanning from the first day of Creation to the death of Abraham's father, Terah.
Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.
Here’s an example using the simplest atom, hydrogen. Carbon-14 is an unstable isotope of carbon that will eventually decay at a known rate to become carbon-12.
They all start with similar flaws, but Carbon-14 has more than the rest.
