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.Click to see full answer. Also to know is, why is lead used as a radiation shield?Lead shielding helps protect from radiation because of its high molecular density. Effective at stopping gamma rays and x-rays, lead is used as radiation protection in applications ranging from x-ray imaging and PET rooms to nuclear reactors.Similarly, what materials can block radiation? Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals that fall into the same category of materials as lead that also absorb or block radiation. These metals may include tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) or other elements. how thick must lead be to block radiation? shield need to be about 13.8 feet of water, about 6.6 feet of concrete, or about 1.3 feet of lead. Thick, dense shielding is necessary to protect against gamma rays. The higher the energy of the gamma ray, the thicker the shield must be. X-rays pose a similar challenge.Is lead apron necessary?While the scattered-radiation exposure to others in the room is very low, many state regulations require that lead aprons be worn by anyone in the CT room during a scan. That practice is also consistent with maintaining radiation exposures to individuals not being scanned as low as reasonably achievable (ALARA).
