Question

For fluoroscopy, the primary protective barrier must be made at least _ of lead equivalent for equipment capable of operating above 125 kVp:

1. 2.5 mm
2. 1.0 mm
3. 2.0 mm
4. 3.0 mm

Answer 1

The correct answer is option 3. 2.0 mm.

Step-by-step explanation:

The question pertains to the standards of protective barriers in fluoroscopy, particularly regarding the lead equivalent thickness required for shielding when the equipment operates above 125 kilovolts peak (kVp).

For equipment operating at these higher energy levels, regulations typically require that primary protective barriers incorporate a lead equivalent of at least 2.0 mm to ensure adequate protection against x-ray radiation.

This ensures that healthcare workers and patients remain shielded from unnecessary radiation exposure during diagnostic procedures.
