How to Self-Decontaminate after a Radiation Emergency
网页2024年4月15日 · It is important to get radioactive material off your body as soon as possible to lower your risk of harm. Removing radioactive material from a person, object, or place is called decontamination. Decontaminating yourself will lower your exposure to harmful radioactive material.
Procedures for Radiation Decontamination - Radiation …
网页Goal of localized skin decontamination: to decrease external contamination to a level of no more than 2 times background radiation level. Perform two decontamination cycles if feasible, with a radiation survey after each cycle. Use tepid decontamination water. Add mild soap (neutral pH) to water to emulsify and dissolve contamination.
