Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology NIST , working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay and found no detectable effect. Atoms of radioactive isotopes are unstable and decay over time by shooting off particles at a fixed rate, transmuting the material into a more stable substance. For instance, half the mass of carbon, an unstable isotope of carbon, will decay into nitrogen over a period of 5, years. The unswerving regularity of this decay allows scientists to determine the age of extremely old organic materials -- such as remains of Paleolithic campfires -- with a fair degree of precision. The decay of uranium, which has a half-life of nearly 4.

How Nuclear Radiation Works | HowStuffWorks

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest OK, maybe the coolest is using radioactive carbon to determine the age of old bones or plants. To understand this, you must first understand radioactivity and decay.

Nuclear Chemistry: Half-Lives and Radioactive Dating

Contact us : Please, you must click on your choices. Emitting b radiation with a half-life of years, Carbon 14 follows the cycle of the stable element C, one of the components of the living materials, in which it is diluted. Carbon is indeed around 10 times less abundant than stable carbon.

Carbon dating is a technique used to determine the approximate age of once-living materials. It is based on the decay rate of the radioactive carbon isotope 14 C, a form of carbon taken in by all living organisms while they are alive. Before the twentieth century, determining the age of ancient fossils or artifacts was considered the job of paleontologists or paleontologists, not nuclear physicists.
