Radioactive dating wikianswers you like to merge this question into it? Would you like to make it the primary and merge this question into it? Merge this question into. Split and merge into it. Edit Answer by P Torquemada. PhD in physical chemistry. Physical chemists radioactive dating wikianswers to do a fair bit of physics as well, as the two disciplines blur into each other somewhat.

Radioactive dating or "radiodating" is a method of determining the approximate age of an object by studying its isotope ratio. A certain percentage of carbon in the environment is radioactive carbon A living organism keeps approximately this percentage, radioactive dating wikianswers it's constantly taking in additional carbon from the environment to replace the amount that decays. However, when the organism dies, it stops taking in new carbon, so by comparing the percentage that's present in the radioactive dating wikianswers with that present in the sample, we can tell approximately how long ago it died.

Other methods differ radioactive dating wikianswers, but the basic idea is the same. Was this answer useful? In BiologyPhysicsRelationships. The process proceeds at the same rate for any given sample of an isotope, such that its mass is reduced by half at some regular interval, called its half-life. The type … of decay is also predictable. Making a graph radioactive dating wikianswers plotting the atomic number vs the mass number of stable isotopes can be used to predict decay.

If you then locate the position of some unstable isotope and it is on one side of the stable isotopes it indicates beta decay, but if on the other side it indicated alpha decay. I'm not sure if there is one word to describe different processes. Thus there can be radioactive decay into a different isotope alpha or beta decaygamma ray emission which … means a change in energy state of the nucleus, nuclear fission as in U in a reactor, and neutron induced radioactive dating wikianswers such as U absorbing a neutron becoming Pu No, radioactive dating does not produce exact results.

No form of radioactive dating produces exact results. But results can be gotten that are surprisingly accurate. As a "fo … r instance" we might look at uranium-lead dating. This dating method can deliver radioactive dating wikianswers accurate to a million or two years in a billion years. There are a number of such isotopes. Geological dating requires isotopes with longer half lives than carbon has. It also requires other things, such as that the elements in … volved do not wash away in water or escape as gas in an unknown manner.

What is usually done is a comparison of radioactive dating wikianswers amount of a radioactive element with the amount of the element it decays into. A link to a Wikipedia article on radiometric dating is given below. Carbon is the parent isotope, its constant decay rate is about years. Which means it takes that many years for it to decay to a stable daughter Nitrogen To determi … ne how old something is you see how much Carbon there is in relation to Nitrogen Carbon can only be used to date something that was once living and under 50, years.
