The purposes of the radiation measurements are the determination of kinds of radiation, intensity of energy, and direction of incident radiations. It is important for radiation protection to know the information on the positions and directions of incident radiations. From this point of view, a circular scintillation fiber detector composed using position sensitive scintillation fiber sensor was constructed for determination of the directional distribution of radiations incident on a certain point of interest. The response function to get the information on incident direction of radiations was obtained by the experiments and was compared with the results by the Monte Carlo calculation method. The fundamental characteristics of the circular detector were investigated by the irradiation experiments using Cs-137 and it was found that the directional information of radiations fields which have two dimensional distributions could be obtained by the present method.
