Radiochemical dating definition chemistry
any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of a long-lived radioactive element plus its decay product.
A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.
(Only in the production of nuclear fuel is Pu obtained in significant quantities, though even here its concentration upon irradiation of U with neutrons is low.) It is therefore possible to separate radioactive elements and isotopes only from extremely dilute systems, and their weights in most cases cannot be determined.
The physicochemical behavior of extremely dilute solutions is very complex.
For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).
Also studied are the properties of radioactive substances and the transformations of these substances under the effect of their own radiation.Our editors will review what you’ve submitted and determine whether to revise the article.Join Britannica's Publishing Partner Program and our community of experts to gain a global audience for your work!You may now see our list and photos of women who are in your area and meet your preferences.Again, please keep their identity a secret Click on the "Continue" button search with your zip/postal code.
to study the mechanisms of complex organic reactions, since even minute amounts of these isotopes are easily detected by means of a Geiger counter or photographic film. Libby Libby, Willard Frank,1908–80, American chemist, b. The decay these isotopes undergo is accompanied by nuclear radiation.
