(57) Abstract In order to be attenuated the said beam the filter element which each becomes independent with the x-ray source forming the x-ray beam and the x-ray detector which inspects the said beam, in respectively, the x-ray filter which possesses the filter element which is provided with the said x-ray source and the said x-ray detector and, the x-ray device which it possesses. As for each filter element, it is possible, to accept the liquid which possesses with electric conductivity and x-ray absorption quality x-ray absorption value of the said filter element depends on the level of the x-ray lean solution of the said filter element. Each filter element, in order to put electric potential on the wall of the said filter element, has the wall of the said filter element and the first electrode (23) which is placed with on the top face of baseplate layer (38). Second electric potential puts on the said liquid via the second electrode. According to this invention, the said first electrode, in order to form with the retention electrode segment (40) and the barrier electrode segment (42) which form the electrode group to which two corresponds, is divided into the lengthwise z of the said filter element. As for function of the retention segment (40) because it is to include the said liquid, the barrier segment (42) forms the potential barrier for the passage of the said liquid in the lengthwise z of the said filter element. The electric apparatus always supplies the voltage in order to fill up the said segment in the said liquid via the power line (26 '') and the switch (25 ''), vis-a-vis the retention segment (40). Gradual filling up of the said filter element is actualized by the application of voltage pulse to the barrier electrode, (40) depends and the passage of the liquid which passes by the said barrier electrode becomes possible.
