ABSTRACT:
Infectious medical materials are rendered harmless by heating heterogeneous medical materials having wet and dry portions with a radio-frequency electric field. The medical materials are exposed to the radio-frequency electric field in order to heat the medical materials to inactivate microorganisms thereon. The medical materials are then irradiated with gamma radiation to inactivate microorganisms remaining viable thereon after application of the radio-frequency electric field.
