Decontamination of exposed crew members with water and soap primarily results in which process?

Explanation:
When decontaminating exposed crew members with water and soap, the primary effect is dilution. Washing off contaminants with water and the soap’s surfactant action lowers the amount of contaminant on the skin by physically rinsing it away and spreading it into the rinse water, reducing the concentration and the exposure risk. Absorption and adsorption are about contaminants sticking to or entering surfaces or skin, which washing aims to remove rather than promote. Neutralization would require a chemical change to render the agent harmless, which water and soap don’t typically accomplish.
