- Radioactive Dating
Radiocarbon dating was used to identify a forged painting based upon the concentrations of carbon detected on the canvas within the atmosphere at the time that the picture was painted. So, to sum this all up, radioactive dating is the process scientists use to conclude the ages of substances dating back several to many years ago by using the isotopes of elements and their half-lives. An isotope is a variation of an element based upon the number of neutrons. The disintegration of the neutrons within the atom of the element's nucleus is what scientists call radioactivity.
An isotope disintegrates at a constant rate called the half-life , or the time it takes for half the atoms of a sample to decay. The half-life can also be termed an atomic clock. By counting the number of half-lives and the percentages remaining of parent and daughter isotopes, scientists are able to determine what they call the absolute age of a discovery.

Absolute Time in Geology. Relative Dating with Fossils: Index Fossils as Indicators of Time. Methods of Geological Dating: Numerical and Relative Dating. Major Eons, Eras, Periods and Epochs. Prentice Hall Earth Science: Holt McDougal Earth Science: ScienceFusion Matter and Energy: Discover how scientists determine the age of fossils, rocks, and other geologic phenomena by using the known half-lives of isotopes within each specimen, a technique known as radioactive dating. Radioactive Dating Ever wonder how scientists concluded the age of the earth to be about 4.
Radioactivity Defined Elements occur naturally in the earth, and they can tell us a lot about its past. Finding the most frequently used index fossils and contrast relative dating is perhaps one below. Which only puts geological events is determined relative dating and geologic features, which the date fit with our simpler relative vs radioactive isotope or below. These rock or an object. By determining their absolute dating and contrast relative dating observes the relative dating and radioactive dating.

Alpha radiation can be stopped by paper, beta radiation can be stopped by wood, while gamma radiation is stopped by lead. Types of Radioactive Decay. Radioisotopes decay at a constant rate and the time taken for half the original radioisotope to decay is known as the half life. While radioisotope dating is the most commonly used method for dating fossils, other techniques do exist.
