特徴とする蛍光Ｘ線測定装置。 A device that is housed in one of two heads arranged oppositely and confronts a sheet-like object running between these heads with a small gap,
A ring-shaped radiation source using a radioactive isotope, which is installed behind the central opening of the radiation source for detecting fluorescent X-rays generated by the constituent materials of the sheet-like object based on the primary radiation from this radiation source. In the fluorescent X-ray measurement apparatus, a collimator is attached to the inner periphery of the central opening of the radiation source, the height of which is adjusted and the path line position with respect to the sheet-like object can be varied. The height of the collimator is set at the inner circumferential edge of the central opening of the collimator. A fluorescent X-ray measurement device characterized in that it is attached to protrude from the inner peripheral edge of a radiation source.
