Radioactive dating isotopes used questions for playing the dating game

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.

Since stable isotopes do not decay, they do not produce radiation or its associated health risks.

Scientists performing environmental and ecological experiments use stable isotopes of oxygen, hydrogen, sulfur, nitrogen and carbon.

Histories of archaeology often refer to its impact as the "radiocarbon revolution".

Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age, and the beginning of the Neolithic and Bronze Age in different regions.

For example, in geochemistry, scientists study the chemical composition of geological materials such as minerals and rocks.

Scientists divide isotopes into two main types: radioactive and stable.Both types see wide use in several industries and fields of study.Stable isotopes have a stable proton-neutron combination and do not display any sign of decay.This stability comes from the amount of neutrons present in an atom.

If an atom has too many or too few neutrons, it is unstable and tends to disintegrate.

The development of radiocarbon dating has had a profound impact on archaeology.
