PETG sing'anga botolondi chidebe chosungiramo pulasitiki chowonekera chomwe chimagwiritsidwa ntchito kusungira seramu, sing'anga, buffer ndi mayankho ena.Pofuna kupewa kuipitsidwa ndi tizilombo toyambitsa matenda chifukwa cha kulongedza, zonsezi ndizosawilitsidwa, ndipo choyikapo ichi chimapangidwa makamaka ndi cobalt 60.

Kutseketsa kumatanthauza kuchotsa kapena kupha mabakiteriya onse, mavairasi, bowa ndi tizilombo tina pa botolo la PETG laling'ono pogwiritsa ntchito njira zosiyanasiyana zakuthupi ndi mankhwala, kuti athe kufika pa chitsimikiziro cha asepsis 10-6, ndiko kuti, kuonetsetsa kuti mwayi wopulumuka. ya tizilombo tosaoneka pa nkhani ndi imodzi yokha mwa miliyoni imodzi.Ndi njira iyi yokha yomwe tizilombo toyambitsa matenda tingapewedwe kuti tisapangitse kuipitsidwa kowonjezera kwa zomwe zili mkati.

Cobalt-60 sterilization ndi ntchito 60Co γ-ray walitsa, akuchita tizilombo, mwachindunji kapena m'njira kuwononga phata la tizilombo, potero kupha tizilombo, kuchita mbali ya disinfection ndi yolera.Ndi mtundu waukadaulo woletsa kuzirala.Ma γ-ray opangidwa ndi radioactive isotope cobalt-60 amayatsa chakudya chopakidwa.M'kati mwa kufalitsa mphamvu ndi kusamutsa, zotsatira zamphamvu za thupi ndi zamoyo zimapangidwa kuti zikwaniritse cholinga chopha tizilombo, mabakiteriya ophera tizilombo komanso kulepheretsa machitidwe a thupi.60Co-γ-ray yoziziritsa kulera ndi ukadaulo wa "cold processing", ndikutseketsa kutentha kwa chipinda, mphamvu ya γ-ray, kulowa mwamphamvu, kutsekereza nthawi yomweyo, sikungayambitse kutentha kwa zinthu, Imadziwikanso kuti njira yoziziritsa kuzizira.
