A Brief History of Ground-Penetrating Radars, Koolaupoko, Hawaii

You never know what lies just below the surface of the ground, which is why contractors use state-of-the-art surveying tools to determine where it is safe to dig. Unfortunately, some of these tools are safer than others, which is why some have questions about GPR, or ground-penetrating radars. Here is a brief history of GPR technology and why you shouldn’t worry about safety. 

Understanding Ground-Penetrating Radar Technology

What Is the History of GPR Systems?

Originally invented in 1910, early ground-penetrating radar systems relied heavily on X-rays to locate buried objects. By the early 1980s, contractors were using large X-ray systems to check for things like underground power lines and foreign metal objects, but these tools were rife with problems. In addition to only being able to scan 20 inches below the surface of the earth, old systems took a long time to collect the data they needed and used radioactive isotopes that compromised the safety of job sites. 

Fortunately, modern GPR systems send pulses of radio waves into the ground and read the results they ping back, creating images that workers can assess in real-time. In addition to giving contractors the opportunity to differentiate between geological materials, modern GPR systems can also detect electricity, water, and man-made materials. 

Should You Worry About Safety?

In fact, research has shown that modern GPR systems emit about 1% of the energy emitted by a standard cell phone signal.
