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.
DTp1 has, in theory, a maximum particle size of 37Â½mm, so using this 'rule of thumb', the min layer thickness would be 3Â½ Ã 2 = 75mm. If a fill layer or sub-base layer was using a 50mm crusher run material, then the minimum layer thickness/depth would be 50 Ã 2 = 100mm, and so on and so forth.
