Izotop węgla C14 powstaje z azotu pod wpływem promieniowania kosmicznego w wyższych partiach atmosfery. Węgiel C14 utlenia się do CO2, który w procesie asymilacji trafia do oragnizmów roślinnych, a potem zwierzęcych. Jeśli roślina lub zwierzę obumiera, to dopływ węgla C14 zostaje przerwany. Od tego momentu następuje systematyczny ubytek izotopu promieniotwórczego. Okres półtrwania C14 wynosi 5730 lat.

W trakcie badania kopaliny stwierdzono, że zawartosć masy izotopu C14 zmniejszyła się o 87,5% w porównaniu z masą pierwotną. Oblicz, ile lat ma badana kopalina.
