Abstract

The invention relates to a seabed in situ X fluorescence measurement influence supervision method and device. The method includes the steps: building a Monte Carlo model, and simulating by the Monte Carlo model, to obtain the transmittance of a target element characteristic X ray under a beryllium window containing no impurities and having different thickness; according to the transmittance and with combination of beryllium window security theory analysis results, determining the optimal thickness of the beryllium window; simulating by the Monte Carlo model to respectively obtain the relationships between the target element characteristic X ray intensity and the target element content under conditions that the beryllium window thickness is the optimal thickness and the beryllium window contains impurities and conditions that the beryllium window thickness is the optimal thickness and the beryllium window contains no impurities, and comparing to obtain a comparison result; according tothe comparison result, judging whether the target element characteristic X ray intensity is affected when the beryllium window contains the impurities, and if the target element characteristic X ray intensity is affected when the beryllium window contains the impurities, correcting the target element characteristic X ray intensity when the beryllium window contains the impurities. The seabed in situ X fluorescence measurement influence supervision method provided by the embodiment of the invention effectively improves the accuracy of the measurement result.

Description

technical field [0001] The invention relates to the technical field of seabed detection, in particular to a seabed in-situ X-ray fluorescence measurement influence monitoring method and device. Background technique [0002] Many western countries have successively applied X-ray fluorescence measurement technology to the composition and content analysis of seabed sediments. The in-situ submarine X-ray fluorescence measurement device manufactured by the US Battle team, the device puts the detection tube into the seabed for in-situ measurement, and transmits the detected signal to the transport ship through the cable for analysis. The detection window of the detection tube has a thickness of 0.127 mm of beryllium window composition. However, this sounding tube is only used for measurements up to a depth of 100m. The X-ray fluorescence analyzer of the University of Georgia in the United States is different from the detection method of the Battle team. It obtains the predicted ...
