Which control is sometimes required in a controlled area to manage potential contamination?

• A. Decontamination procedures
• B. Free entry
• C. No dosimetry
• D. None

Answer: (A)

Decontamination procedures are used in controlled areas to remove or reduce contamination on people, equipment, and surfaces so contaminants don’t spread outside the area. They’re applied when there’s a potential for contamination and help ensure that exposure and contamination levels stay within limits. Typical steps include removing contaminated outer garments, washing or showering, changing into clean clothing, and properly handling or bagging contaminated items, often followed by surveys to verify cleanliness. This control is important because allowing free entry would bypass safeguards, and skipping dosimetry would miss monitoring exposure, which is still needed in many controlled scenarios. None would imply no control is needed, which isn’t true when contamination risk exists.
