Answer»

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.
