You are given a very old sample of wood. How will you determine its age?
The age of the wood sample can be determined by radiocarbon dating as 14C becomes a part of a plant due to the photosynthesis reaction (i.e., absorption of [14CO2 + 12CO2].
- The activity (N) of a given wood sample and that of a fresh sample of the live plant (N0) is measured, where, N0 denotes the activity of the given sample at the time of death.
- The age of the given wood sample, can be determined by applying following Formulae:
t = `2.303/lambda log_10 "N"_0/"N"`
where `lambda = 0.693/(5730 "y") = 1.21 xx 10^-4 "y"^-1`
