Radioactive Dating

Carbon-14 has a half-life of 5700 years.  It decays by beta minus decay by this equation:

 

carbon 14

Carbon-14 is made by the collision of an energetic neutron with a nitrogen nucleus, which results in the ejection of a proton.  The energetic neutron is formed by cosmic ray activity.  Therefore carbon-14 is being made all the time. The rate of decay is balanced by the rate of formation, so the amount of carbon-14 remains almost constant.

 

The proportion of carbon-14 in living material is very low.  For each gram of carbon, the count-rate is about 140 min-1, 2.33 Bq.  The count rate is therefore 2300 Bq kg-1.

Nitrogen 14 is stable: https://en.wikipedia.org/wiki/Isotopes_of_nitrogen#Nitrogen-14

Carbon 12 is stable: https://en.wikipedia.org/wiki/Isotopes_of_carbon

carbon 14

The above diagram shows how a stable isotope changes into a radioisotope.
