Abstract
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.
Claims11
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.
A measurement apparatus for detecting radioactive contamination of an object, which can move in a longitudinal direction through the measurement apparatus, characterized by
- a plurality of detectors, which are arranged in the longitudinal direction for detecting a radiation source moving through the measurement apparatus,
- an evaluation device, which captures repeatedly a count rate of each of the detectors during a movement of the object and
- the evaluation device weights the measured count rates of the detectors in that the count rates of the detector(s) that have a greater separation distance from the object to be measured are weighted lower than the count rate of the detector(s) that have a smaller separation distance from the object.
