C14 methode wikipedia
WebUhlíková metóda C14 alebo rádiokarbónová metóda datovania je fyzikálny postup používaný na stanovenie veku organických zvyškov (napr. v archeológii).Princípom metódy je znalosť polčasu rozpadu izotopov uhlíka 12 C a 14 C a fakt, že v živom organizme je pomer oboch izotopov konštantný, ale po smrti sa tento pomer pozvoľna mení vďaka … WebThis discovery meant that there are three naturally occurring isotopes of carbon: carbon-12 (c12), comprising 99% of carbon atoms. carbon-13 (c13), comprising about 1% of carbon atoms. carbon-14 (c14), represented by one carbon atom per trillion. Whereas carbon-12 and carbon-13 are stable isotopes, carbon-14 is unstable or radioactive.
