Radiation contrast improvement by suitable choice of x-ray radiation spectrum

الملخص EN

Different bremsstrahlung spectra from tungsten anode x-ray tube generated at 30, 40 and 50 kV have been examined theoretically and experimentally for an attempt to find a most suitable spectrum to radiograph a test object of 0.01 cm thickness of Cu and Ag.

The high contrast using this suitable spectrum is demonstrated and the possible effects of fluorescent radiation are discussed.
