By using an X-ray analyzer, it is possible to evaluate the performance of an X-ray apparatus, such as tube voltage, exposure time and irradiation dose. In this study, a comparison of irradiation dose was made using two X-ray analyzers(NERO 6000B and Model 100)and the conventional direct readout dosimeter(ionization chamber). The irradiation dose determined by Nero almost agreed with that by the conventional direct readout dosimeter for the 2-peak, 12-peak, constant potential and inverter-type X-ray generators. The irradiation dose determined by Model 100 dose not necessarily agreed with that by the conventional direct readout dosimeter at a lower tube voltage. The error is attributed to the detection theory(direct or indirect)of X-ray analyzers. The stability and reproducibility results by X-ray analyzers were excellent. Moreover, X-ray analyzers were safe and easy to handle. Therefore, they can be used for controlling the quality of X-ray generators, though we have to be careful about a characteristics of X-ray analyzers.
