Disclosed is a filter assembly for a radiographic apparatus, which is positioned at an illumination part of a radiographic apparatus. The disclosed filter assembly for a radiographic apparatus includes a radiation shield filter including silicon dioxide (SiO2), aluminum oxide (Al2O3), boron trioxide (B2O3) and sodium oxide (Na2O), and a radiation alignment filter composed of the same components as the radiation shield filter, laid over the front of the radiation shield filter and having fine holes formed in the surface thereof, and effectively blocks the radiation generated from the radiographic apparatus without greatly affecting the quality of a radiographic image.
