The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

Then Prince Joseph comes along, and not a single person after him lives more than 130 years As a side note, the Genesis account seems to indicate that the famine has something to do with something EAST of Israel. The waters boiled, and the creatures residing therein also died.

From all points of the compass the arrows of the flame rained continuously!

George de Hevesy The first practical application of a radioisotope was made by George de Hevesy in 1911.

At the time de Hevesy was a young Hungarian student working in Manchester with naturally radioactive materials.

The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.It is the radioactive nature of these unstable atoms, usually referred to as 'radioisotopes', which gives them so many applications in modern science and technology.Their radioactivity means that they can be used as a tag to follow the movement of some material incorporating them.Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.The first power station to produce electricity by using heat from the splitting of uranium atoms began operating in the 1950s.
