There is described a handheld inspection device for inspecting an infrastructure having a structure wall at least partially supported into material such as soil. The handheld inspection device generally has a portable frame; a high energy photon source mounted to said portable frame and having a radioactivity level below a threshold radioactivity level; a scattered photon detector mounted to said portable frame and having a field of view diverging towards said target region of said infrastructure and encompassing at least a portion thereof, said scattered photon detector detecting scatter events incoming from said target region during a given period of time, and generating a signal indicative of scatter events detected during said period of time; and a controller receiving said signal generated by said scattered photon detector; and generating an integrity indication associated to said target region of said infrastructure based on said received signal.

A local area cosmogenic neutron sensor is used for detecting moisture within a measurement surface. A neutron detector is positioned on a stand structure holding the detector above a measurement surface. A moderator material and neutron shield are positioned around at least a portion of the neutron detector. The neutron shield substantially covers lateral sides and an entirety of a top of the neutron detector and is not positioned on a bottom side of the neutron detector. A second neutron shield is positioned below the neutron detector and in a path of neutron travel between the measurement surface and the neutron detector to substantially block neutrons from reaching the neutron detector.

A system is provided. The system includes a conveyor apparatus configured for conveying a material and a water content measurement system positioned about the conveyor apparatus for determining water content in the material. A dimension characteristic measurement system for detecting one or more dimension characteristics of the material is provided and a computer device is configured to manipulate data received from the water content measurement system and the dimension characteristic measurement system to determine a water content of the material.

The present invention relates to a system (S) and a process for determining the water equivalent content of a snowpack (Snow Water EquivalentSWE).

A method of determining material composition of a target includes identifying a component of the material composition of the target by matching a Compton scattering background, in a spectrum of detected X-rays acquired by irradiating the target with a source of X-rays during a nominal source exposure time period, to a Compton scattering spectrum for the component; and reporting the material composition of the target including the identified component of the material composition.

A system is provided. The system includes a conveyor apparatus configured for conveying an asphalt material and an asphalt cement measurement system positioned about the conveyor apparatus for determining asphalt cement content in the material. A dimension characteristic measurement system for detecting one or more dimension characteristics of the material is provided and a computer device is configured to manipulate data received from the asphalt cement measurement system and the dimension characteristic measurement system to determine an asphalt cement percentage (AC %) of the material.
