Also, it wouldn't be nearly as localized as you'd think.
Most things are relatively transparent to x-rays. Take concrete, for instance. Depending on wavelength, the "penetration depth" (the depth at which half the x-rays are absorbed ) is 4-60mm (or higher, but then you've moved up into gamma rays). For comparison, take the penetration depth to be 1cm for simplicity. Now look at a light bulb. Now move twice as far away from it and look at it again. That change in light intensity is the equivalent of a 2cm chunk of concrete for x-rays.
You try to, say, weld an I-beam and a significant chunk of the x-rays would just go right through into whatever is behind it.
Not to mention the amount of x-ray scattering that would happen.
