Technetium haina basa rakasikwa uye haisi kuwanikwa mumuviri wemunhu. Technetium inogadzirwa muhuwandu nekuparadzaniswa kwenyukireya, uye inopararira zviri nyore kupfuura mamwe ma radionuclides. Inoita kunge ine huturu hwakaderera hwemakemikari. Semuenzaniso, hapana shanduko yakakosha mu formula yeropa, huremu hwemuviri nemitezo, uye kudya kwechikafu kunogona kuonekwa kumakonzo ayo akapinza kusvika ku15 μg ye technetium-99 pa gramu yechikafu kwemavhiki akati wandei. Iyo radiological huturu hwe technetium (pauniti yehuremu) ibasa remubatanidzwa, mhando yemwaranzi yeiyo isotope iri mubvunzo, uye hafu yehupenyu yeisotope.
