Which of the following is a method to control contaminated tools, equipment, and materials?

• A. Minimize material contaminated
• B. RCA tool issues point
• C. Use tools/equipment in RCA room
• D. Friskers or pcm

Answer: (C)

Keeping contaminated tools and equipment inside the Radiation Control Area prevents the spread of contamination. Using and handling tools within the RCA confines any potential contamination to a controlled zone where it can be contained, decontaminated, and properly disposed of before leaving. This minimizes the chance that radioactive material or other contaminants get onto clean surfaces, clothing, or into other work areas, which also helps protect workers and reduces cleanup effort later. Tools can be decontaminated and waste managed according to established RCA procedures, and the area can be monitored to verify it remains uncontaminated.

The other options don’t directly control contamination: reducing how much material becomes contaminated is a goal but not a practical method for ongoing work; the phrase about an RCA tool issues point isn’t a recognized control method; and friskers or pcm devices detect contamination but don’t by themselves prevent its spread.
