The two main points to consider are (a) the depth of penetration of the primary X-Ray beam into the sample, and (b) the escape depth from which fluorescent X-Rays can be detected. Both of these are directly linked to the energy of the X-Rays - the higher the X-Ray energy the deeper the X-Ray . The higher the voltage used to produce the x-rays the shorter the wavelength and therefore the higher the penetrating power. Wood is not a very dense material and does not contain elements of high.
Although x-raying remains a viable and accurate testing method for mapping objects embedded in concrete, x-ray companies must ensure safety by clearing people from a large area around their x-ray location. They must create a safe and controlled environment. Penetration is the degree to which X-rays have passed through the body. Assessment of penetration is traditionally a standard part of assuring chest X-ray quality. With modern digital viewing systems, over or under penetrated images are rarely a problem.
Concrete x-ray is the non-destructive application of hard x-rays or gamma rays to image the interior of a concrete target to identify and locate rebar, conduit, post tension cables and other embedded objects. X-ray penetration is probabilistic – some gets through, some does not. It would be useless to us if it got through % of the time or 0% of the time. It is only useful to us because ‘some’ of what does get through is able to be detected by film or excites a scintillator that is digitally detected. X-ray penetration is always non-zero.
