PETG ibhotile mediumsisikhongozeli seplastiki esicacileyo esisetyenziselwa ukugcina i-serum, medium, buffer kunye nezinye izisombululo.Ukuze uthintele ukungcoliseka kwe-microbial okubangelwa ukupakishwa, zonke zibulawa inzala, kwaye le phakheji ivalwa kakhulu yi-cobalt 60.

Ukubulala inzala kuthetha ukususa okanye ukubulala zonke iintsholongwane, iintsholongwane, umngundo kunye nezinye microorganisms kwi PETG ibhotile medium ngeendlela ezahlukeneyo ngokwasemzimbeni kunye nemichiza, ukuze ifikelele kwinqanaba isiqinisekiso asepsis 10-6, oko kukuthi, ukuqinisekisa ukuba ukusinda amathuba. iimicroorganisms kwinqaku sisinye kuphela kwisigidi.Ngaloo ndlela kuphela i-microorganisms kwi-package ingathintelwa ukuba ibangele ukungcoliseka okongeziweyo kwezinto zangaphakathi.

I-Cobalt-60 inzala kukusetyenziswa kwe-60Co γ-ray irradiation, esebenza kwii-microorganisms, ngokuthe ngqo okanye ngokungathanga ngqo i-nucleus ye-microorganisms, ngaloo ndlela ibulala i-microorganisms, idlala indima yokubulala iintsholongwane kunye nokuvala inzala.Luhlobo lobuchwephesha bokuvala inzala kwimitha.I-γ-ray eveliswa yi-isotope cobalt-60 ye-radioactive irradiate ukutya okupakishweyo.Kwinkqubo yokuhanjiswa kwamandla kunye nokudluliselwa, iziphumo eziqinileyo zomzimba kunye nebhayoloji ziveliswa ukufezekisa injongo yokubulala izinambuzane, iintsholongwane zebhaktheriya kunye nokuthintela iinkqubo ze-physiological.I-60Co-γ-ray irradiation sterilization yitekhnoloji "yokucoca ngokubanda", i-sterillization kwiqondo lobushushu begumbi, i-γ-ray yamandla aphezulu, ukungena okunamandla, ekubambeni inzala ngaxeshanye, akuyi kubangela ukwanda kobushushu bezinto, ekwabizwa ngokuba yindlela yokuvala inzala ebandayo.
