Radioactive Dating: Questions Answered Answers in

Aug 14, 2018  What is radioactive dating and absolute dating? Radioactive dating is just one form of absolute dating. That form employs radioactive isotopes which decay at a known rate and so if a particular radio active isotope was pres ent when the object was created and the fraction which decayed can be determined, then the age can be. Radiometric dating is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. The decay rate is referring to radioactive decay, which is the process by which an unstable atomic nucleus loses. Apr 08, 2007  Best Answer: All those radioactive dating works the same way. All elements have what is called a halflife. What this is, is a period (usually in years) where the amount of certain elements in the object becomes half of what the original values were. For example, carbon14 has a halflife of 5730 years. Thus, the necessary assumptions on which the radioactive clocks for the dating of rocks are based are unprovable.

Radioactive dating uses the decay rates of radioactive substances to measure absolute ages of rocks, minerals and carbonbased substances, according to How Stuff Works. Scientists know how quickly radioactive isotopes decay into other elements over thousands, millions and even billions of years. Radiocarbon dating is based on the fact that organisms contain approximately equal amounts of normal 12C and 14C (carbon12 and carbon14). Carbon 14 is radioactive, so it decays over time into other atoms.
