Most hospitals in Indonesia have already been provided with the digital radiography room in their radiology installation rooms. This room utilizes the lowest X-ray level to diagnose, and this kind of radiation, if not well-managed, will become one of the hospital’s pollutant sources namely the danger of radiation exposure. Related to the room’s design, the government, by means of the Ministry of Health Regulation No. 1014 of 2008 and the Chairman of Nuclear Energy Supervisory Agency Regulation No. 8 of 2011, requires the brick wall with 25 cm thickness, 2.2 g/cm3 density, and 2 meters height from the floor or equal to 2 mm lead layer (Pb), which serve as the room’s partition (the secondary shield). However, in its implementation, most of shielding partition wall designs in hospitals’ digital radiography rooms use the 15 cm half brick wall coated with 2 mm lead layer (Pb).
