Question

Ceiling-mounted lead acrylic screens and moveable shields must have _____ mm Pb.

Option 1: 2.0
Option 2: 3.5
Option 3: 1.5
Option 4: 4.0

Answer 1

Ceiling-mounted lead acrylic screens and moveable shields must usually have 1.5 mm of Pb to provide adequate radiation protection.

Step-by-step explanation:

For ceiling-mounted lead acrylic screens and moveable shields used for radiation protection, the standard thickness required is generally 1.5 mm of lead (Pb) equivalent. This thickness is effective at attenuating the amount of radiation to a level that is safe for medical personnel working in proximity to diagnostic imaging machines or during interventional radiological procedures. It's important to note that the required thickness can vary depending on factors such as the energy of the radiation.
