In experiments searching for rare signals, background events from thedetector itself are some of the major factors limiting searchsensitivity.Screening for ultra-low radioactive detector materials is becomingever more essential. We propose to develop a gaseous time projection chamber(TPC) with a Micromegas readout for radio screening. The TPC recordsthree-dimensional trajectories of charged particles emitted from a flat sampleplaced in the active volume of the detector. The detector can distinguish theorigin of an event and identify the particle types with information fromtrajectories, which significantly increases the screening sensitivity. For$\alpha$ particles from the sample surface, we observe that our proposeddetector can reach a sensitivity higher than 100 $\mu$Bq$\cdot$m$^{-2}$ withintwo days.
