When applying ionizing radiation, we must think about the influence on the radiation within the PPE by itself. It is understood that ionizing radiation can problems polymeric supplies by triggering cross-linking or scissioning the molecules [33]. These chemical adjustments might end in embrittlement, lack of tensile energy, and loss of molecular excess weight, all depending on the polymer being irradiated.
Note that it is not the stress in the autoclave that kills the microorganisms even so the high temperature which can be reached when steam is put under pressure.
