How is carbon dating used

Production rates vary because of changes to the cosmic ray flux caused by the heliospheric modulation (solar wind and solar magnetic field), and due to variations in the Earth's magnetic field.The latter can create significant variations in The New Zealand curve is representative for the Southern Hemisphere, the Austrian curve is representative for the Northern Hemisphere.

In 1960, Libby was awarded the Nobel Prize in chemistry for this work.The carbon-14 method was developed by the American physicist Willard F. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.The method is widely used by Pleistocene geologists, anthropologists, archaeologists, and investigators in related fields.Atmospheric nuclear weapon tests almost doubled the concentration of The above-ground nuclear tests that occurred in several countries between 19 (see nuclear test list) dramatically increased the amount of carbon-14 in the atmosphere and subsequently in the biosphere; after the tests ended, the atmospheric concentration of the isotope began to decrease.One side-effect of the change in atmospheric carbon-14 is that this has enabled some options (e.g., bomb-pulse dating Carbon-14 is produced in coolant at boiling water reactors (BWRs) and pressurized water reactors (PWRs).

Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California.
