Organic material carbon dating
Carbon-14 is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms: C ratio of 0.795 times that found in plants living today. Solution The half-life of carbon-14 is known to be 5720 years. Radioactive decay is a first order rate process, which means the reaction proceeds according to the following equation: is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.
As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.
date of organic material - but an approximate age, usually within a range of a few years either way.
These rocks normally form relatively horizontal, parallel layers, with younger layers forming on top.It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.
