Therefore whereas a dental x-ray room may require a. nominal shielding of about 1.5mm lead for the direct beam and. about 0.7mm lead for the scattered field, a diagnostic x-ray. room may require a nominal shielding of about 3mm and 1.5mm. for the direct beam and scattered field respectively.
Of all options, lead shielding offers the utmost radiation protection at increased cost-effectiveness. Lead provides the most space-savings and the greatest amount of shielding to meet your radiation protection needs. One effective use of nuclear shielding is the use of lead castles in nuclear research and testing. Lead castles are structures composed of lead bricks. The lead castle encloses the radioactive source or it may be used to shield people from radiation.
