WebThe X-ray is focused on the sample at some angle θ, while the detector opposite the source reads the intensity of the X-ray it receives at 2 θ away from the source path. The incident angle is than increased over time while the detector angle always remains 2 θ above the source path. X-ray Tubes Webzero. However, X-ray beams are typically filtered to minimize the low-energy component. •Low-energy X-rays are not useful in radiography, but can deliver a significant dose. …
