![]() ![]() However, it requires bulky beamshaping equipment around an X-ray tube, which is of considerable size, not counting the high-voltage power supply and water-cooling system to keep from melting the tube's cathode. In the real world, there is a technology called "X-ray backscatter imaging" which allows for a certain amount of selective viewing. Sometimes this has unintentionally humorous effects, as when some characters repel-everything super armor turns out to be completely radiotransparent, allowing you to see his/her skeleton beneath. X-ray scopes, goggles, visors and what-have-you are perennially popular items in video games. Presumably you'd "see" things thus revealed in a "colour" for which we normal, X-ray-blind people have no name. ![]() Whether your eyes or your glasses are sensitive to X-rays, you would still need a powerful X-ray source on the other side of whatever you were trying to see through, and even then you'd only see things that were X-ray opaque. How the power actually works, especially if it's implied to be actual X-rays, is confusing. It can usually be turned on or off at will, and the objects that you can see through and how far you see through them vary. If you need such services, please contact an appropriate professional.A power that lets one see through almost anything. Note: GPRS does not provide geophysical, geological, land surveying or engineering services. GPRS was able to identify and locate numerous underground utilities including fire waterlines, communication lines, electric lines, sanitary sewer lines, gas lines, and storm drains in the ground and mark them on the surface in order for the client to proceed with their work safely. Here is an example of a jobsite where GPRS was contacted by an electrical contractor in Dallas, Texas to locate underground utilities prior to directional boring for a new underground electric line. With the aid of advanced utility technology, like the GPR, utility contractors to can “see” what is buried underneath. A line strike can add thousands of dollars in project costs and can sometimes be dangerous or even deadly. In addition to the high cost of potholing, the poorly or undocumented buried utilities can result in many months of project delay.īuried infrastructure suffers from “out of sight, out of mind”. ![]() It is the most accurate but by far the costliest method. Potholing, digging holes to locate utilities, is another way to identify buried utilities. It’s extremely valuable when you can’t see what you are looking for. This is because GPR reflects off changes in dielectric property between two materials, like between soil and a PVC pipe. One of the benefits of this technology is that it makes no distinctions in materials. These units send out an electromagnetic wave down into the ground if it hits anything, it sends a signal back in the form of a reflected wave. The GPR can locate non-metallic material, it often gets used in applications where the previous electromagnetic methods aren’t well suited. It is used to locate lines that are made of metal or have conductive tracer wire. The locating equipment generates an electromagnetic radio signal that is directed onto the utility line. It is one of the most common and cost-effective techniques. Products used to locate metal or metallic lines are based on electromagnetic (EM) detection, a technology that has been around for a long time. The technology helps reduce the guesswork and can answer questions like what exactly lies in the subsurface of a job site? Where is it and how deep is it?ĭifferent technologies are required for detecting metal, plastic, concrete pipes, and fiber cables. The construction industry, therefore, heavily relies on various types of underground detection technologies. For example, an old abandoned natural gas pipeline could have retained significant quantities of flammable methane that could explode upon contact with an excavator bucket. Even abandoned and decommissioned utilities can prove dangerous. In some parts of the country, utilities are more than 100 years old, and many utilities have been added or abandoned without being recorded. Records of a site’s underground utilities may be available but unfortunately, utilities and contractors know that there is no reliable paper record. Damaging utilities can be costly, leading to cost overruns and project delays. Contractors must know the locations of these utilities before any construction project begins as contractors can’t risk damaging expensive utilities or endangering their work force.
