The present invention relates to a radiation filter box used for air ventilation and air cleaning of radio-nuclide treating facilities, which includes: a body part with an inlet and an outlet, forming an outer housing; a filtering element installed inside the body part with a plurality of steps, and discharging radioactively contaminated air flowed in through the inlet through the outlet after cleaning the air; and a filter opening/closing part formed on the body part. The body part is composed of and assembled with multiple assembling type body parts. Specifically, an external body is composed of multiple assembling type body parts. A filter filtering the radiation and blocking the radiation from being leaked to the outside of the body part during a filtering process of air containing radiation materials, has a drawer-type replacement structure. |
