DEVICE AND METHOD FOR DETECTING DEPOSITS ON AN INNER SURFACE OF A PASSAGE
摘要
A method and device for detecting mercury or other material deposits on an inner surface of an enclosed passage are provided. The device includes a detection unit that is adapted to be transported through the passage, and the detection unit includes a radiation source and an x-ray fluorescence detector. The radiation source is configured to emit a radiation emission toward the inner surface of the passage to excite a portion of the inner surface, and the x-ray fluorescence detector is configured to detect a resulting x-ray emission from the portion of the inner surface to identify a material deposit on the inner surface. The detection unit can identify material deposits at successive positions along a length of the passage and thereby generate a plurality of data points, each data point providing an indication of a material deposit existence for a corresponding position along the length of the passage.
