Correction factors for attenuation of beta radiation by spherical quartz grains embedded in ceramics were obtained for grain diameters ranging from 0. 005 to 10.0 mm. The calculation was based on the absorbed-dose distributions for point-isotopic beta sources listed by Berger, in conjunction with the scaling procedure developed by Cross, and included beta particles, internal conversion electrons, and Auger electrons emitted by ₄₀K, and the ₂₃₃Th and ₂₃₈U series.
