National
Aeronautics and Space Administration (NASA) as a result of their initial investment in research and development activities to bring the LixiScope to market. NASA grants Lixi Research Limited Partnership a partially exclusive license for the isotope version of the LixiScope on November 29, 1982.

The company establishes a domestic medical and industrial domestic network and operates internationally through distributors and original equipment manufacturers. Lixi’s customers include AT&T, RCA, Texas
Instruments, Hughes, Xerox, General Motors, General Electric, Motorola, TRW, Intel, Ford and

In 1996, the
American Petroleum Institute (API), through the Petroleum Environmental Research Forum (PERF), funded a project via a grant to Lixi. The intent was to develop a device that was very portable and hand-held, with technology that could identify the presence of corrosion under insulation in

The Lixi
Profiler is configured for conventional or rope access use, light weight, and battery operated for complete portability. The tool is assembled, calibrated, and ready to use within minutes by a trained and skilled technician. The low-level gamma radiation source is approved for on-person air

Radiometric
Profiling (RP) can be applied to any material, though is most commonly used to test the mechanical integrity of industrial steel piping. Other current applications include locating and measuring defects in metal support structures, timber bridges, copper tubing, high density polyethylene
431:
Material is introduced between the energy source and an energy detector. The detector measures the amount of energy passing through the material (displayed as counts) and a pre-defined calibration allows for the conversion of detector measurements into calibrated values typically expressed in units
591:
The Lixi
Profiler, a hand-held portable device, utilizes the physics of Radiometric Profiling. The Profiler has proven to be an excellent tool for detecting CUI, High Temperature Sulfidation Corrosion (HTSC), moisture in insulation, liquid levels in piping, verifying if gate valves are fully open,
391:
The operating technician can use different scanning techniques to achieve different desired outcomes. The two (2) most common techniques, slice scan and axial scan, are typically used to measure or find indications of degradation, abnormalities, liquid levels, blockages, or hidden pipe components.
358:
Radiometric
Profiling (RP) is a non-contact, rapid, real-time non-destructive testing technique that can be applied to any material. This application measures changes in a beam of gamma-ray energy as it passes through the sample being tested. The beam source is positioned on one side of the sample

Lixi, Inc. receives approval from the U.S. Nuclear
Regulatory Commission (NRC) in 1985 to distribute the LixiScope to licensed users in the industrial and medical markets. The U.S. Food and Drug Administration grants Lixi, Inc. permission to market the LixiScope for medical use. Lixi's industrial

Radiometric
Profiling is applied with the Lixi Profiler, a hand-held tool connected to a portable computer with proprietary technology for recording captured data. The subject is scanned with the arm (available in multiple sizes to accommodate different subject diameters) of the Lixi Profiler.
427:
Radiometric
Profiling measures the attenuation of a highly collimated radiation beam, with a very small radioisotope of Gadolinium-153 as an energy source, directed at a specialized detector. It then converts gamma rays to visible light in the form of photons. The detection system measures the

Lixi, Inc. was incorporated April 18, 1978 as an Illinois corporation to manufacture, sell, distribute and service the LixiScope. The name LIXI is actually an acronym for Low Intensity X-ray Imaging. The LixiScope and its technology are based in U.S. Patent 4,142,101 which was assigned to the
435:
For example, if a corroded area is scanned over with the Lixi Profiler, then the scan will reflect a loss of density equivalent to the loss of steel. For example, if a pit 2.50mm deep is scanned over, the Profiler will show a reduction in the graph from 21.50 mm to 19.00mm Assuming that the

This method is unique in that it can accurately test bare and insulated material, including in-process piping, as-is. The low-level gamma-ray allows for personnel to be present while testing; there is no radiation risk or required safe work area designations.

August 1986, Lixi, Inc. introduces its Microfocus x-ray system for the surface mount device inspection market. Lixi, Inc. also begins to provide peripheral equipment and accessories due to customer demand for complete turnkey systems.
