Tuttavia, essendo un prodotto di fissione spontanea dell'uranio, il tecnezio-99g è presente in natura in tutti i minerali uraniferi. Il <sup>99g</sup>Tc è un contaminante radioattivo e deve essere sempre maneggiato in un box sigillato dotato di guanti manipolatori in opportuni laboratori di <a href="/wiki/Chimica_nucleare" title="Chimica nucleare">radiochimica</a>. Tutti i nuclidi del tecnezio sono radioattivi. Questo elemento non ha alcun ruolo provato in biologia, tuttavia il radionuclide a breve <a href="/wiki/Emivita_(fisica)" title="Emivita (fisica)">emivita</a> <sup>99m</sup>Tc viene ampiamente impiegato in medicina nucleare per marcare numerosi farmaci con diversa cinetica e diversa dinamica metabolica. La versatilità del <sup>99m</sup>Tc ne permette dunque l'impiego per lo studio di diversi organi e apparati. Per esempio nel Nord America, dove vengono compiute circa 35 milioni di indagini <a href="/wiki/Scintigrafia" title="Scintigrafia">scintigrafiche</a> di medicina nucleare ogni anno su un bacino d'utenza di 300 milioni di abitanti, il 50% fra queste è eseguito con questo radionuclide.
