“Radiometric age-dating is based on the fact that every radioactive element decays. The original or “parent” element emits radiation and particles until the loss thereof transforms it into a stable “daughter” element. A series of transformations into other radio-active elements marks its unparalleled pattern and rate of decay until it reaches stability (Think Quest).” “The decay of radioactive elements occurs at different rates, depending on the specific isotope. These rates are stated in terms of half-lives. One half-life is the amount of time required for ½ of the original atoms in a sample to decay (O'Neil).” Radiometric methods provide one of the most important ways to date fossils. The main types of radiometric dating are Potassium-argon, carbon-14 or radiocarbon, thermoluminescence, and electron-spin-resonance. Potassium-argon dating is used for dating volcanic rocks associated with fossil material. It can date better for older specimens but when used for younger specimens it can give a wrong date. You have to be careful and use the right method for the selected
