The correct answer is  Ans. is 'c' i.e. 0.5 mm "It is recommended that for general purpose radiography the minimal thickness of lead equivalent in the protective apparel should be 0.5mm." - Textbook of Radiology Physics p. 39* Lead apron of 0.5mm thickness reduce intensity of scattered X-rays by over 90%.Lead apron* A lead apron or leaded apron is a type of protective clothing that acts as a radiation shield. It is constructed of a thin rubber exterior and an interior of lead in the shape of a hospital apron. The purpose of the lead apron is to reduce exposure of a hospital patient to x-rays to vital organs that are potentially exposed to ionizing radiation during medical imaging that uses x-rays (radiography, fluoroscopy, computed tomography).* 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.* Protection of the reproductive organs with a lead apron is considered important.* The thyroid gland is especially vulnerable to x-ray exposure. Care should be taken to place a lead apron over the thyroid gland before taking dental radiographs.
