The use of carbon 14 in radioactive dating definition
carbon14 is a weakly radioactive isotope of carbon also known as radiocarbon it is an isotopic chronometer c14 dating is only applicable to organic and some inorganic materials not applicable to metals gas proportional counting liquid scintillation counting and accelerator mass spectrometry are the three principal radiocarbon dating.
As its produced carbon14 reacts with oxygen to form carbon dioxide and some of it is taken in by green plants and made into sugars along with the normal carbon.
radioactive contamination also called radiological contamination is the deposition of or presence of radioactive substances on surfaces or within solids liquids or gases including the human body where their presence is unintended or undesirable from the international atomic energy agency iaea definition such contamination presents a hazard because of the radioactive.
