Experiments are made for the application of scattered gamma rays in the labyrinth for shielding of a Co-60 gamma ray cave. The scattered gamma rays are suitable to the radiography of thin samples, because of their low energy. In contrast with the case of the ordinary point source radiography, the gamma rays in the labyrinth come from random directions because of the considerably larger area of the scattering sources and of the complicated shape of the labyrinth. In order to get a parallel beam, the hood should be as long as possible. However, the use of a longer hood requires longer exposure times, because of the decrease of the dose rate. Experiments are made on the exposure diagram, parallelism of the beam in the hood (geometrical unsharpness), and perception sensitivity for various hood lengths (sectional area 100 mm x 100 mm).
