The objective of this study was to search for the low cost and appropriate materials that can be used to fabricate a shielding for radiation protection in dentistry. Using a radiation dosimeter, the amount of reduced radiation dose (mR) was measured after passing through consecutively increasing numbers of sheets of four materials which were zinc alloy plate (1 sheet thickness = 0.200 mm); aluminum alloy plate (1 sheet thickness = 0.185 mm); wood plate (1 sheet thickness = 3.938 mm); and used soft drink can (1 sheet thickness = 0.150 mm.). The half value layer of each material was calculated. The results showed that zinc alloy plate had the best half value layer at 1 sheet (thickness = 0.200 mm). Wood plate, aluminum alloy plate, and used soft drink cans had half value layer at 12 sheets (thickness = 47.25 mm.), 17 sheets (thickness = 2.96 mm.), and 20 sheets (thickness = 3.57 mm.) respectively. In conclusion, it was found that using 12 sheets of zinc alloy plate sandwiched by 2 sheets of wood plate acted as an acceptable barrier for scattered radiation in dentistry.
