Gamma radiation exposure decontamination guidelines indicate which action is required?

• A. No Decontamination Required
• B. Immediate Decontamination Required
• C. Partial Decontamination Only
• D. Decontaminate With Soap And Water

Answer: (A)

Gamma exposure means the person has received penetrating radiation dose, not necessarily that radioactive material is on their skin or clothing. Decontamination is the process of removing radioactive contamination from the person or gear to prevent further exposure or internal uptake. If there is no evidence of contamination, washing or decontamination does not reduce the dose and isn’t required. The priority is to minimize exposure risk through time, distance, and shielding, and to assess for contamination with appropriate monitoring. Decontamination should be performed only if contamination is present, such as removing contaminated clothing and washing exposed skin to remove radioactive material.
