Lead Apron - an overview | ScienceDirect Topics

Lead Aprons. For reasons of weight, lead aprons generally have shielding equivalence equal to a 0.25–0.5-mm lead barrier, and will only attenuate the radiation. Lead aprons absorb 90%–95% of scattered radiation that reaches them (Table 77.5). "Wrap-around" lead aprons are useful when medical personnel spend a lot of time with their ...

Lead shielding - Wikipedia

Lead shielding refers to the use of lead as a form of radiation protection to shield people or objects from radiation so as to reduce the effective dose.Lead can effectively attenuate certain kinds of radiation because of its high density and high atomic number; principally, it is effective at stopping gamma rays and x-rays. A rubber coated lead apron protects organs from exposure to x-rays.
