Radiology Practice Test

An impregnated sheet is a type of protective sheet that contains a layer of lead within the material. This lead layer helps to shield the body from harmful radiation during medical procedures such as X-rays. Option A, a rubber dam sheet, is used in dentistry to isolate the teeth during procedures and does not provide radiation protection. Option B, a soft tissue sheet, is typically used as a surgical barrier and does not contain lead. Option D, an X-ray film packet, is used to hold X-ray film but does not have any protective properties.
