Summary
Discussion, based on nuclear, geochemical and astronomical data, on the possible existence of isotopes of technetium with a period longer then 109 years. The only possible isotopes are Tc97 and Tc98 which, although radioactive, might have very long periods.
Riassunto
Discussione in base a dati nucleari, geochimici e astronomici sulla possibile esistenza di isotopi, del tecneto con periodo superiore a 109 anni. I soli isotopi possibili sono Tc97 e Tc98 i quali, benchè radioattivi, potrebbero avere periodi lunghissimi.
