1. An apparatus for rendering infectious medical material harmless, comprising:

  • a radio-frequency treatment unit for accepting medical material to be treated;

    means for transporting infectious medical material in closed bulk containers through the radio-frequency treatment unit;

    means for energizing the radio-frequency treatment unit with the time-varying electric field having a frequency below the frequency of microwave; and

    means for injecting inert gas into the radio-frequency unit thereby to sweep oxygen therefrom to avoid oxidizing heated medical material and to cause a flow of gas from a relatively cool portion of the radio-frequency treatment unit to a relatively warm portion and thereby to prevent any vapor which might have escaped from the medical material from condensing on cooler medical material entering the radio-frequency treatment unit.
