From the experiences in individual monitoring at Tsuruga Nuclear Power Station of JAPC, it has been shown that measured values of the film badge worn by radiation workers exceed those of the pocket dosimeter placed in the same position of their bodies.In order to solve this problem concerning the individual monitoring, γ-ray dose rate spectra were measured in the working places of the nuclear power station and the response of the film badges was compared with that of other monitors.The following results were obtained;1) The contribution of γ-ray of the energies higher than 3-MeV to total γ-ray dose rate is greater than a half at the working places examined.2) Measured values of the film badge with Cd and Pb filters are relatively larger than those of other monitors.From the discussion about individual monitoring, it is concluded that it is important to improve the accuracy of individual monitor to be used at high energy γ-ray field.
