Carbon dating acurate

Radiocarbon dating is an radioactive isotope dating technique used in dating materials which contain the unstable carbon-14 isotope.Radiocarbon dating is used to determine the age of previously living organisms.It gets taken from the air and used in photosynthesis by plants, and so all living things should have this same fraction of 14C in them as long as they are alive and actively exchanging matter with the environment.When something dies its 14C begins to decay away and by measuring how much 14C is left in some dead thing (either by counting the decay rate with a Geiger counter or running it through a mass-spectrometer) we can measure how long ago it died. Basically, 14C has a half-life of about 5,730 years.
