The procedures used to isolate and analyze the parent and daughter nuclides must be precise and accurate. New York, McGraw, p. Strata which were deposited on top of one another without interruption. For example, the age of the Amitsoq gneisses from western Greenland was determined to be 3. Accuracy levels of within twenty million years in ages of two-and-a-half billion years are achievable. The carbon dating limit lies around 58, to 62, years. Some radioactive parent isotopes decay almost instantaneously into their stable daughter isotopes; others take billions of years. The equation is most conveniently expressed in terms of the measured quantity N t rather than the constant initial value No. It is not affected by external factors such as temperature , pressure , chemical environment, or presence of a magnetic or electric field. Many elements have naturally occurring isotopes, varieties of the element that have different numbers of neutrons in the nucleus.
