摘要： PURPOSE:To eliminate the effect of the etching conditions which differs by the film and thus obtain the good measurements of the radiation, by dividing the solid jumped trace detecting film into three regions in terms of the radiation irradiation and then setting those regions to the optical system to obtain the standardized radiation quantity. CONSTITUTION:Unirradiated part 1, standard irradiating part 2 and measuring irradiation part 3 of film A are set to the path of optical system 6 each. And each output of detector 8 is referred to as to IO, IS and IX each when the radiation is irradiated. And when carrying out the measurement, part 1 is set first and then IO is set to 0 via zero-point control catch 9 of indicator 12. Thus the effect of the light volume transmitting through the film base is eliminated. Then part 2 is set manually to the optical path via sensitivity control catch 10, and the full scale is set then. And when part 3 is set to the optical path, the output corresponding to IX-IO is obtained at indicator 12. Thus the measurements is obtained in the form of the standardized relative value to the standard irradiation quantity.
