In a Hot Cave labyrinth system, the dose rate of scattered gamma rays was difficult to calculate accurately. An approximate formula was derived by which the dose rate of scattered gamma rays coming out of the labyrinth is obtained. The value calculated by the approximate formula was compared with the measured value of the actual Hot Cave as well as with that of mcdels and found to be almost identical, the error staying within 10%. In this formula, the multiple scattering inside the shielding was ignored and the scattering was taken as being isotropic. These approximations were shown to be satisfactory at the labyrinth where it bends at right angles. By this formula the labyrinth shape which should be adopted for Hot Caves in order to obtain the most effective shielding was computed. The calculated value was compared with the actual value measured in both a lead and ordinary concrete. (auth)
