Experiments with metallic containers filled with aqueous solutions of colloidal gold (Au/sup 198/, E2 = 0.411 Mev) and NaCl (Na/sup 24/, E = 1.38 Mev and E/sub 2/ = 2.76 Mev) showed that at given geometries the attenuation of gamma rays from extended sources is similar to the attenuation for a point source when the build-up factor is (V = K/sub theor.//K/sub exp./). The build-up factor for the extended sources is less than for the point source and depends on the shape. The buildup factor increases with reduced gamma energy and decreases with the increase of the absorber atomic number. The increase in a three-dimensional-extended source in a lead absorber is close to 1.0 at mu l ( 3. (R.V.J.)
