Radiokarbonizotópok
Radiokarbonizotópok refer to radioactive isotopes of carbon. The most significant naturally occurring radioactive isotope of carbon is carbon-14 (¹⁴C). Carbon-14 is continuously produced in the Earth's upper atmosphere when cosmic rays interact with nitrogen atoms. This ¹⁴C then combines with oxygen to form carbon dioxide, which is absorbed by plants during photosynthesis and subsequently enters the food chain as animals consume plants or other animals.
The key characteristic of ¹⁴C is its radioactivity, meaning it decays over time. The half-life of carbon-14
