Which of the following is NOT an administrative control to prevent the spread of contamination in a radiology facility?

• A. PPE
• B. Contamination zoning
• C. Training
• D. Decontamination protocols

Answer: (A)

Administrative controls are policies, procedures, and organizational measures that shape how work is performed to prevent the spread of contamination. Contamination zoning establishes where work can occur and how movement is restricted, training ensures staff know and follow the proper procedures, and decontamination protocols define the standardized cleanup steps. Personal protective equipment, while essential for protecting individuals, is a protective barrier worn by the worker rather than a system-level change to the environment or workflow. It does not reorganize processes or cleanup routines, and thus is not considered an administrative control. Therefore, PPE is the option that is not an administrative control.
