What treatment method applies ionizing radiation to eliminate pathogens in infectious waste?

Irradiation is the correct answer because it utilizes ionizing radiation to effectively target and eliminate pathogens present in infectious waste. This method involves exposing the waste to radiation, which disrupts the DNA or cellular structures of pathogens, rendering them inactive and incapable of causing infection. It is particularly effective for sterilizing medical supplies and waste that may contain various infectious agents.

This method stands out for its ability to penetrate materials and eliminate a broad spectrum of pathogens, making it a crucial technique in healthcare settings where the safe disposal of infectious waste is necessary to prevent the spread of disease. By utilizing ionizing radiation, healthcare facilities can ensure that their waste is treated adequately to protect public health and safety.
