The period of time that it takes for half of the parent isotope to decay into daughter isotopes is called the half-life of an isotope (Figure 5b). When the portions of the father or mother and daughter isotopes are equal, one half-life has occurred. If the half life of an isotope is known, the abundance of the mother or father and daughter isotopes could be measured and the amount of time that has elapsed because the “radiometric 
clock” started could be calculated.
Description – Since The Second World War, there’s been large success in the introduction of recent technique of courting artifacts the so-known as `radiocarbon revolution’ was simply the very first such discovery.

There are quite lots of scientific strategies that archaeologists use to research the age and origins of fossils, stays, or other artifacts. Dating strategies can enable bio-archaeologists to find out elements corresponding to environment, food plan, health, or migration patterns of people, crops, or animals. Knowing the age of an object of fabric tradition, how it was made, and the surrounds in which it was found, also assist classical, historic, or ethnoarchaeologists to higher hypothesize the purpose or cultural meaning that might have been attributed to it up to now. Ordering archaeological finds inside time periods throughout traditions is how archaeologists piece together the previous that connects all contemporary cultures at present.
