IGCSE PHYSICS (20) - RADIOACTIVITY - WikispacesThe isotope 14 C, a radioactive form of carbon, is produced in the upper atmosphere by neutrons striking 14 N nuclei. The neutron is captured by the 14 N nucleus and knocks out a proton. Thus, we have a different element, 14 C. The isotope, 14C, is transported as 14 CO2, absorbed by plants, and eaten by animals.Gamma radiation nas no. equation for the nuclear reaction involved in the beta decay of the carbon-14 atom. measured using carbon dating.

The unstable Carbon-14 within the organism begins to decay to form Nitrogen-14 by emitting a beta particle. Over time there is a gradual decrease in the amount of Carbon-14 and the ratio of Carbon-14 atoms to other Carbon atoms declines. The half life for Carbon-14 is 5730 years. Therefore half of the Carbon-14 has decayed after 5730 years.Radiocarbon dating (also referred to as carbon dating or carbon-14 dating). which counted the amount of beta radiation emitted by decaying 14.
