Many people view the term X-ray to refer to the process done on human beings. This is application of X-rays to human anatomy which many people know. The term is however also applicable in other fields in life. Case in point is application in construction. This is the use of related rays in finding out what is inside concrete. These are called concrete X-rays.
What is the meaning of the term concrete X-rays? Concrete X-rays refers to the application of gamma rays in concrete surfaces. This is done to identify any unwanted objects that are in the concrete slab. Objects being located includes post tension cables and rebar. By identifying and removing them one can establish firmness in the slab.
You can group concrete X-rays among many things that are within industrial radiography. Many years ago when this technology was not with us people would have to damage concrete just to check if there are any embedded objects inside. This method meant so much work needed to be done and redone in addition to the high costs involved. With concrete X-rays you do not have to actually destroy any part of the concrete structure. Best application is usually in slabs that are suspended and walls that are to be renovated.
In modern days where much technology equipment may pass inside or near concrete walls, concrete X-rays also work magic. It is possible at times for cables such as those in telecommunication and electricity to pass through concrete surfaces. Also in this category are traffic lighting and cable television’s cables. The location of such cables can be determined with easy by using concrete X-rays. This is called utility location.
In the United States utility location is done very often so as to ensure safety of electricity cables as well as other utilities. Utility location in Los Angeles for instance is done both day and night and very frequently to guarantee safety of utilities and in extension people. The case is the same for concrete surfaces in Irvine, California. Both private companies and government institutions have taken up concrete X-rays as a modern way of handling infrastructure issues.
Concrete X-ray technology works just like other X-rays. A beam of rays leads to casting of a shadow of the concrete on another platform. It is this projection that shows what is inside the slab. By using the rays, one can identify any objects within the concrete surface. Two people are usually needed to accomplish this especially in Los Angeles. The two stand on opposite sides so as to have a clear image of the concrete slab as well as ensuring that nothing is between the wall and the gamma rays. If you apply concrete X-rays on a small surface then it can be expensive but for large scale work the cost goes down proportionately.
