Concrete X-raying is in fact a inaccurate term since many tradesmen utilise it to refer to ground penetrating radar. Leading to the confusion is the fact that, even though cement radiography is increasingly being superseded with GPR, the older technology is currently in use.
Concrete X-raying includes making x-ray pictures of concrete slab to figure out where post-tension cables, rebar and conduits are located in it. The X-ray unit can easily go through up to 30 inches inside of the slab and perhaps even deeper dependent on its composition, then make very detailed visuals which are easier to interpret when compared with GPR information.
What are the other variations between concrete x-ray and ground penetrating radar?
1. Cement radiography needs to be processed off-site. The results of the scan are placed onto x-ray film, which still has to be developed before the results can be viewed. Having GPR, the end results instantly show up on the unit's electronic display. However, a number of radiography providers have mobile darkrooms that allow the film to be|developed on location, so you have the results quickly.
2. Concrete X-raying uses each side of the slab for scanning, with one end containing the film and the other the reflector plate. Due to this, there are constraints with the thickness of the slab being examined. If you use iridium-based radiography equipment, you are able to check out a slab up to twelve inches, whilst by using cobalt-based radiography you'll be able to check the slab with a ma thickness of thirty-six inches.
3. Concrete radiography requires the operator to put on safety gear like a lead apron to make sure they're protected, as well as having an eighty foot space around the slab to ensure that viewers will not be exposed to rays from the x-ray device.
4. Concrete X-raying is actually pricier than ground penetrating radar because of the higher cost of the apparatus involved together with the salary of the x-ray technician working with it. Alternatively, the GPR operator can be educated to deal with the apparatus in as little as a day, although you will still need an experienced technician to be able to interpret the data.
5. Cement radiography can't gather facts on large building sites. In order to obtain info from larger slabs, you will need to constantly set up the concrete x-ray device at several spots where you want to take readings. By comparison, GPR is a tool which can take readings of large areas just by being set up once.
