The dependence of radiation effect on individuals led to the actualization and acceptance of the standard man in the 1940s, the standard man later transformed into the reference man in 1963. The definition of the reference man was a Caucasian data, so it conflicts with the physiology, anatomy and the metabolic data of the Asian people; this was challenging for the Asians and races from other adversely affected regions globally. Hence, the Asian man project was instituted but with the exclusion of the Malaysian people. Malaysia, being a tri-racial country therefore lag in reference man data. This is the gap this study intends to fill. In this study, a survey of 450 male and 450 female Malaysians (18-24 years) were used to collect data on the mass, height and the BMI. The total population of the Malaysian male and female within the age range and confidence interval of 95% with margin error of 5% were used as variables to arrive at the population of 450 that was used as a benchmark population for the survey. A mean value for the mass, height and BMI were obtained from this survey sample. An equation was derived from the International Commission for Radiation Protection, ICRP reference data and the Asia Reference Man, ARM data to estimate the needed dataset for the Malaysia phantom. The observed difference between the mass obtained from the equation and the mass obtained from the survey is less than 0.01% of the survey mass. The derived equation was appropriated and used to estimate the mass of the internal organs for the proposed Malaysian phantom. The volume equivalent of the internal organs was estimated using the simple density-mass-volume relation while the voxel number was estimated from the volume estimate. This was achieved using the respective recommended densities of the internal organs and the specified voxel numbers for ICRP male and female voxel phantom. These estimated values of the mass, volume and voxel number of the internal organs for the proposed Malaysian male and female are meant to be used for the modification of an existing radiation phantom or to serve as a background data for the construction of a new phantom
