Question

What is the thickness of the lead jacket that is maintained for X-Ray procedures?

(a) 0.25 mm

(b) 2.5 mm

(c) 25 mm

(d) 250 mm

This question was addressed to me by my college director while I was bunking the class.

My doubt stems from Standard Hospital Procedures topic in section Hospitals of Clinical Science

Answer 1

Correct answer is (a) 0.25 mm

To explain: X – Rays are high energy radiations and cause damage to the body if exposed for long periods of time. Thus, it is important to wear protective materials to reduce the exposure and damage from the X – Rays. Since lead can be used to block X – Rays, a lead jacket of 0.25 mm is used. The front and back of 0.25 mm make the total thickness to be 0.5 mm.
