A device for detecting neutrons emitted from fluids and the detection method

摘要

A device for detecting neutrons emitted from fluids consists of a sampling vessel to which the fluid is supplied by the inlet and outlet piping, a control valve on the inlet or outlet piping, and a neutron detector enclosed outside or in its opening by a neutron moderator connected to evaluation device. A method of performing detection by a device for detecting neutrons emitted from fluids is characterized in that the fluid flow is repeatedly started and interrupted so that at least 10% of the fluid in the sample vessel is replaced during opening. The method of performing a detection by means of a device for detecting neutrons emitted from fluids is also characterized in that during the flow and interruption of the fluid flow, a signal is detected by a neutron detector with a sampling interval of less than 300 carbon blacks. characterizing the amount of neutrons emitted from the fluid.
