Carbon dating has the peculiar property that it works primarily on dead things.Another common technique in dating an object is carbon dating.Because the amount of carbon-14 has remained roughly constant through time on the earth it is possible to calculate the age of an object by finding the proportion of carbon-14 to carbon-12.The proportion of potassium to argon suggests how old the object in question is.

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.

No, radioactive dating does not produce exact results.
