half life is the time taken for half the mass of a radioactive sample to
decay, when compared with other stable
isotopes , it it make it possible to
predict the age of ancient object.
archeologist, uses radiocarbon dating
to predict the age of organic object,
since both plant and animal have same proportion of carbon-12 and
arbon-14 in their body, when a plant or
animal dies the intake of both isotopes of carbon stops and he decay of
carbon-14 starts, the variations between the proportion of the carbons in
living and death is ten used to ascertain the age of objects.
