Type radiation used carbon dating
Dating techniques are procedures used by scientists to determine the age of an object or a series of events.
These plants are eaten by animals who, in turn, are eaten by even larger animals.When the organism dies, the supply stops, and the carbon-14 contained in the organism begins to spontaneously decay into nitrogen-14.The time it takes for one-half of the carbon-14 to decay (a period called a half-life) is 5,730 years.The age of the remains of plants, animals, and other organic material can be determined by measuring the amount of carbon-14 contained in that material.Carbon-14, a radioactive form of the element carbon, is created in the atmosphere by cosmic rays (invisible, high-energy particles that constantly bombard Earth from all directions in space).
These include the uranium-thorium method, the potassium-argon method, and the rubidium-strontium method. Thermoluminescence (pronounced ther-moeloo-mi-NES-ence) dating is very useful for determining the age of pottery.
