Carbond dating

Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years.Other useful radioisotopes for radioactive dating include Uranium -235 (half-life = 704 million years), Uranium -238 (half-life = 4.5 billion years), Thorium-232 (half-life = 14 billion years) and Rubidium-87 (half-life = 49 billion years).As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used).This fact should always be remembered when using radiocarbon dates.

C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. Carbon dating has given archeologists a more accurate method by which they can determine the age of ancient artifacts. Libby invented carbon dating for which he received the Nobel Prize in chemistry in 1960.Carbon has unique properties that are essential for life on Earth.Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.
