This non-destructive inspection system 1 has a non-destructive inspection device 2 and a management device 3. The non-destructive inspection device 2 is provided with: a neutron emission unit 10 capable of emitting a neutron beam; a gamma ray detection unit 20 capable of detecting gamma rays; a device casing 30 covering the neutron emission unit 10 and the gamma ray detection unit 20, an opening 30a being formed in the device casing 30; an outer shutter 31 that opens/closes the opening 30a; dose monitors 51, 52, 53 provided to the device casing 30, the dose monitors 51, 52, 53 detecting the radiation dose; a device communication unit 56 capable of transmitting device information including the detected radiation dose to the management device 3, and capable of receiving inspection permission information from the management device 3; and a device control unit 40 that, when the inspection permission information is acquired, opens the outer shutter 31 and enables emission of a neutron beam from the neutron emission unit 10.

A non-destructive inspection device includes a neutron generation portion, a neutron shield portion, a gamma ray detector, and a gamma ray shield portion. The neutron generation portion emits neutrons spontaneously, or emits neutrons by DD nuclear fusion reaction or DT nuclear fusion reaction. The neutron shield portion is covers the neutron generation portion from at least an area around the neutron generation portion and thereby shields the neutrons at the area, and allows the neutrons to be emitted to a front side of the neutron generation portion. The gamma ray detector detects gamma rays generated in an inspection object on a front side of the neutron generation portion. The gamma rays are generated by the neutrons incident on the inspection object. The neutron shield portion, the gamma ray shield portion, and the gamma ray detector are arranged in this order in alignment with each other in a lateral direction.

A method for real time on-stream analysis of oil sands composition is disclosed comprising the steps of detecting a moisture content of an oil sands stream using a microwave transmission analyzer, detecting an elemental composition of the oil sands stream using a prompt gamma neutron activation analyzer and calculating a content of hydrocarbons, clays and sands in the oil sands stream. The total clay amount in the oil sands stream is based on the detected gamma spectra of several elemental components of the oil sands stream, such as sodium, magnesium, potassium, calcium and iron.

Systems and Methods for an air slide analyzer for measuring the elemental content of aerated material traveling by air slide. The air slide analyzer has an analyzer having an entrance opening and an exit opening, and an interior tunnel adapted for aerated material conveyed by an air slide; a radiation detector proximal to the analyzer; a neutron source emitting neutrons into material within the analyzer; and a processor to analyze detected information from the radiation detector, wherein emissions from the material being irradiated with neutrons are detected by the radiation detector and analyzed by the processor to provide elemental information of the material in the analyzer.

Methods and systems are disclosed wherein neutrons are produced by a photon induced process 2D(,n) and the ensuing neutrons are thermalized and captured by hydrogen producing a 2.223 MeV gamma that is used to identify and quantify the presence of hydrogen and which, when combined with NRF signals from certain isotopes, can be used to establish the nature of a hydrogenous compound or a mixture of hydrogenous materials or a mixture of hydrogenous materials with other non-hydrogenous materials. The method is useful to establish, e.g., the presence and quantification of explosives, toxic substances and general contraband as well as the flow of materials in a production line or shipping venue.

Moisture content in a sample material undergoing elemental activation analysis (EAA) is determined. The sample material contains a sample element which during EAA forms an activation product. A reference material, distinct from the sample element, is positioned in vicinity of the sample material. The reference material contains a reference element having a thermal neutron capture cross-section. The reference material is selected such that its product isotope of a thermal neutron capture reaction is a radioisotope that emits gamma-rays. The sample material and the reference material are irradiated with a source of fast neutrons to produce thermal neutrons in the sample material. Signals are generated representative of detected gamma-rays emitted from the reference material. A factor, R, proportional to the thermal neutron flux, is calculated based on the generated signals. From a relationship relating moisture content to R, the moisture content in the sample material is determined.

A system may include one or more downhole tools, where a first downhole tool includes a pulsed neutron generator to emit neutrons into a borehole of a geological formation and one or more gamma-ray detectors to obtain a measurement of gamma-ray emissions, of a borehole environment, induced by the emitted neutrons. The system may also include data processing circuitry to determine a Sigma value associated with the borehole environment based on the measurement and determine elemental concentrations, excluding lithium, based on one or more gamma-ray energy spectra obtained via the one or more downhole tools. The data processing circuitry may also determine an elemental Sigma contribution of the elements other than lithium based on the elemental concentrations, determine a lithium Sigma contribution based on a difference between the Sigma value and the elemental Sigma contribution, and determine a lithium concentration within the borehole environment based on the lithium Sigma contribution.

A measurement system 50 measures a grade of an excavated material generated from an underground tunnel including a plurality of mining points. The underground tunnel is constructed based on a mining plan of a mine planned based on primary grade data and primary position data corresponding to the primary grade data measured in a preliminary geological survey. The measurement system includes a measuring unit (grade measuring unit) 61 that measures the grade of the excavated material generated from the underground tunnel, a secondary grade data acquisition unit (grade data acquisition unit) 72 that acquires secondary grade data indicating the grade of the excavated material from the measuring unit 61, and a secondary position data acquisition unit (position data acquisition unit) 73 that acquires secondary position data corresponding to the secondary grade data.
