What does the exit portal contamination monitor check for?

• A. Radioactive contamination in employees
• B. Temperature of the portal
• C. Time since last shift change
• D. Noise level in the area

Answer: (A)

The exit portal contamination monitor is about ensuring that no radioactive material is carried out of a radiological area. It screens personnel as they leave to detect any residual contamination on skin, clothing, or equipment. If contamination is detected above allowed levels, decontamination steps are taken before they re-enter non-controlled areas, preventing spread of contamination to others and to the outside environment. So, it checks for radioactive contamination in employees. The other options—temperature of the portal, time since last shift change, and noise level in the area—are not what this device measures.
