The invention relates to a method for the biological decontamination of material to be treated (4) by means of a reactive gas (R) comprising the generation of a reactive gas (R) from a process gas by igniting a plasma, filling a container (3) with the reactive gas (R) and the Decontamination of the material to be treated (4) in the container (3) by means of the reactive gas (R).
The invention further relates to a plasma ignition device (20) comprising an electrically conductive base plate (201) and at least two electrically conductive pins (202), the plasma ignition device (20) being designed to create an electric field between the pins (202) by resonance with microwaves to generate, wherein a plasma can be ignited by means of the electric field.
The invention also relates to a system (1) for the biological decontamination of items to be treated (4) by means of a reactive gas (R) with a container (3) for receiving items to be treated (4) and a plasma ignition device (20).
