The ERESCO 65 MF4 is a 300 kV constant potential portable X-ray tube head using state of the art switching technology with high radiation output allowing shortest exposure time’s thereby increasing productivity. GE Sensing & Inspection Technologies uses the number 65 to identify the superior penetration performance of its Radiography is the use of X-rays on cross-materials to view inside objects. A heterogeneous beam of X-rays is produced by an X-ray generator and is projected toward an object. According to the density and composition of the different areas of the object, a portion of the X-rays are absorbed by the object. The X-rays that pass through are then captured behind the object by a detector (film sensitive to X-rays or a digital detector), which gives a two-dimensional representation of all the structures superimposed on each other. Detected and measured to determine the density of the material, variations in this amount (or intensity) of radiation are used to determine thickness or composition of material and detect discontinuities in the material.
