What technique is used to find the extent and intensity of radiological contamination?

• A. Indirect
• B. Direct Scan
• C. Course Leg
• D. Surface Profiling

Answer: (C)

A structured surface survey conducted along straight-line paths, or legs, across the area is used to determine both where contamination is and how strong it is. As you move along each leg, you take readings with a radiological detector at regular intervals. Collecting these readings on every leg lets you build a map showing the extent of contamination (where it exists) and the intensity (how high the contamination levels are). This leg-by-leg approach covers large areas efficiently, helps you identify hotspots, and defines boundaries so you can plan decontamination and assess potential dose impacts.
