Claims

[Scope of utility model registration request]

a ring-shaped radiation source using a radioactive isotope housed in a head placed between a traveling sheet-like object and placed in a minute gap with the sheet-like object;
a detector provided behind the central opening of the radiation source, and the detector detects fluorescent X-rays generated by the constituent materials of the sheet-like object based on the primary radiation from the radiation source. The measuring device includes: a case that houses the radiation source and the detector and is fixedly installed in the head; a sliding shutter mechanism that slides over a radiation irradiation window of the case to block radiation; Furthermore, a fluorescent X-ray measurement apparatus is provided with a standard sample entrance/exit mechanism that raises the standard sample to a certain height and rotates the standard sample above the radiation irradiation window during calibration.
