In Indonesia, there are many types of wood with potential as radiation shielding materials—specifically, woods possessing a certain degree of hardness that could serve as substitutes for lead (Pb). Bulian wood (Eusideroxylon zwageri), also known as ironwood, is one of the most well-known and strongest species in its native habitat, the Sumatran forest. It is highly durable, resistant to termite and boring insect attacks, impervious to fluctuations in humidity and temperature, and even resistant to seawater. Research into the radiation absorption capacity of Bulian wood is therefore highly necessary, particularly to explore its viability as a substitute for lead metal in radiation shielding applications. This study aims to examine the absorption capacity of Bulian wood with varying thicknesses, which is then analyzed in terms of its density equivalence on film compared to lead sheet objects. The research is quantitative and utilizes an experimental method. It was conducted in the radiography laboratory of the Faculty of Vocational Studies, Baiturrahmah University. The research sample consists of film density measurements at each thickness variation of Bulian wood, corresponding to each level on the step wedge. Data were processed using bivariate analysis.
