Ground Penetrating Radar (GPR) versus X-ray
The use of GPR in construction, inspection, and concrete repair has many advantages over older X-ray methods. Simply put, GPR is safer, more economical, more versatile and more accurate than X-ray.
- More Economical - GPR gives real-time on-site results so it takes a fraction of the time of X-ray development and processing.
- Safer - GPR uses an electromagnetic radar pulse that has no harmful effects. X-ray processes require a potentially dangerous radiation source and require evacuation of adjacent areas.
- More Versatile - GPR only requires access to one side of concrete slabs to image them. X-ray requires two-sided access so the X-ray film can be placed on the opposite side for exposure.
- More Accurate - GPR displays real-time 3-D images at your location with proven accuracy. X-ray film can mistakenly be rotated, flipped, or improperly lined up to provide inaccurate target locations.
X-ray requires the evacuation of surrounding areas (which includes floors 50' above and 50' below) due to radiation safety concerns. Just this fact alone makes GPR a superior alternative to X-ray. The time lost because of evacuation can be substantial depending on the size of the project. GPR units are easily portable and can be "in and out" in a fraction of the time and they eliminate the safety concerns of dealing with a radiation source.
When you consider all the factors, Ground Penetrating Radar is clearly a better solution for the concrete inspection, construction, and repair industry than X-ray methods.
