One such example is potassium-argon dating, where potassium decays into argon.

The proportion of potassium to argon suggests how old the object in question is.

Scientists find the ratio of parent isotope to daughter isotope.

Radioactive dating is a technique used to find how old an object is.

Half-life is the amount of time it takes for half of the parent isotopes to decay. In another 5,730 years, the organism will lose another half of the remaining C-14 isotopes.

An equation used is t = (1/c)Ln(1 (D/P)) Where c is the decay constant D is number of daughter atoms (number decayed) P is the number of parent atoms (number undecayed) t is the age of the object.

Another common technique in dating an object is carbon dating.

We can get absolute ages only if we have rocks from that surface.

For others, all we are doing is getting a relative age, using things like the formation of craters and other features on a surface.

The lab also uses Carbon-14 analysis for natural product source testing on materials such as flavors, fragrances, essential oils, cosmetics and supplements to identify petrochemicals.
