"Mix D" phantom wax, which was developed by Jones and Raine, was made by the authors but its density was only 0.96 g/ml. In order to increase the density, the quantities of paraffin and polyethylene were reduced and in- stead pine resin, with a density of 1.07 g/cu cm was added to the composition of "Mix D." The composition of the new material by weight is paraffin wax 50%, polyethylene 25%, pine resin 16.2%, magnesium oxide 6.4% and titainium dioxide 2.4%. The density of this material became 0.99 g/ml. The effective atomic number was estimated by taking a radiograph of a block of the material immersed in water. Using 50 kvp x rays, a block of the new material was not imaged on the radiograph. By irradiating x rays of 65 kvp, 130 kvp, and 180 kvp and Co/sup 6// sup 0/ gamma rays, comparative tests were made on transmission of rays and 135- degree scattering under the similar arrangement between water and the new phantom material. The new material gave the same absorption and scattering as a water phantom within the limits of experimental error. (Abstr. Japan. Med., 1: No. 1, 1960)
