Current HUD regulations dictate that lead must be abated if the concentration, as measured by an xrf detector, exceeds?

• A. 2.0 micrograms cubic centimeter
• B. 1.0 micrograms cubic centimeter
• C. 0.5 micrograms cubic centimeter
• D. 1.0 micrograms per square centimeter

Answer: (B)

The main idea here is the threshold used to decide whether lead-based paint requires abatement when measured with an XRF detector. HUD sets a specific action level for lead concentration, and if the XRF reading is at or above that level, abatement must occur. In this item, the value that matches that trigger is 1.0 micrograms per cubic centimeter. The other options either use different units or a different magnitude that does not align with the HUD threshold specified for this context. So the 1.0 micrograms per cubic centimeter reading best fits the required abatement trigger.
