METHOD FOR DETECTING CONTAMINATION ON A MOVING OBJECT AND MEASUREMENT APPARATUS FOR THIS

摘要

A method for detecting contamination on a moving object moving in a longitudinal direction past a plurality of detectors, wherein - a count rate is captured repeatedly by each of the detectors during the movement of the object past the detectors, - the captured count rates are weighted in that the count rates of the detector(s) that have a greater separation distance from the object to be measures are weighted lower than the count rates of the detector(s) that have a smaller separation distance from the object to be measured.
