How is contamination removed from personnel?

The removal of contamination from personnel is most effectively accomplished using mild soap and lukewarm water. This physical method helps to wash away radioactive materials or any hazardous contaminants from the skin or surfaces of clothing. Mild soap can effectively break down contaminants and the action of rubbing with water helps to dislodge particles from the skin without causing irritation, which could happen with harsher chemicals.

In a contamination scenario, it's crucial to utilize proper techniques to ensure that all radioactive particles are adequately washed away. Lukewarm water is preferred because it is comfortable for the skin and effective at dissolving contaminants without causing additional stress to the individual. This method is also non-invasive, making it suitable for personnel who may be exposed to radioactive materials in a work environment.

Other options do not represent appropriate methods for removing contamination. Medical intervention might be necessary in cases of significant contamination or exposure but does not directly address the removal process. Supervision is important for safety and ensuring procedures are followed but does not assist in the physical act of decontamination. Personal protective equipment (PPE) is used to prevent contamination in the first place rather than to remove it.
