Which of the following is NOT a method of decontamination?

Decontamination refers to methods used to remove or neutralize contaminants from surfaces or individuals to reduce the risk of radiation exposure or contamination. Among the methods listed, exposure to sunlight stands out as not being a recognized method of decontamination for radioactive materials.

Damp wiping is a common decontamination method, where surfaces are wiped down with a damp cloth to remove contamination. This technique effectively captures dust and particulates that may contain radioactive materials.

Using a neutralizing agent is also a valid decontamination approach, especially when dealing with specific types of contaminants that can be chemically neutralized. This could involve applying a substance that reacts with the contaminant to render it harmless or more easily removable.

Vacuuming is another effective decontamination method, particularly for loose contamination, as it helps collect and remove contaminant particles from surfaces. Specialized vacuums may be used to ensure that radioactive materials are contained and not released back into the environment during the cleaning process.

In contrast, while sunlight has some sterilizing properties when it comes to pathogens, it is not an effective method for decontaminating surfaces from radioactive materials. Radioactive isotopes do not break down or become non-radioactive simply from exposure to sunlight, thus making this
