A mathematical model of a phantom simulating the body and major internal organs of a Japanese adult has been developed for use in computer calculations of radiation dose. The total body height of the mathematical phantom is 162 cm, and the total body mass is 55 kg based on densities of 0.3, 1.4, and 1.0g/cm^3 for the lung, skeleton, and bulk tissues of the body, respectively. The Health Physics Division of the Oak Ridge National Laboratory (ORNL) has participated for a number of years in liaison studies with the Atomic Bomb Casualty Commission (ABCC), which was recently reorganized and renamed the Radiation Effects Research Foundation (RERF). These studies have been concerned with the development of techniques for estimation of radiation dose received by survivors of the 1945 bombings of Hiroshima and Nagasaki, Japan. As a part of liaison studies continued by RERF and ORNL, a mathematical phantom has been developed to simulate the body and major internal organs of a Japanese adult. This phantom is similar mathematically to one developed previously at ORNL to represent standard or reference man as defined by the International Commission on Radiological Protection (ICRP).
