SETT FOR KVANTITATIV METNING AV KONCENTRATIONEN AV VATTEN OCH MINST EN SPECIFIK KOMPONENT I ETT MATERIAL SAMT ANORDNING FOR UTFORANDE AV SETTET

摘要

Techniques and apparatus for measuring the concentration of water and specific components in materials are described. The techniques involve irradiating the material with neutrons and monitoring the neutron flux in th vicinity of the irradiated material and the gamma radiation from excited nuclei of the specific component. Examples of the use of the invention include on-stream monitoring of ores carried by conveyor belts and borehole logging using a probe which carries a neutron source, and neutron and gamma radiation detectors.
