The thickness of the block is at least equal to one-tenth of the mean free path traveled by the incident ionizing radiation particles in the material. Parallel slits run through the block and the slits are filled with a fluid configured to interact with the secondary particles to produce other particles representing the radiation. The block, and then the slits, are formed, for example, by waterjet cutting, electrical discharge machining, or roll-out stretch wire. The bidimensional detector can be used, for example, for radiographic purposes.
