Response of air, silicon and dosimetric films to x-ray spectra of various qualities.
Calculations have been performed of the kerma to radiographic film and to silicon from a number of x-ray spectra generated at 30 to 140 kV with tungsten and molybdenum targets. These results have been compared with the air-kerma values due to the same beams. It is concluded that both film and silicon can be used as practical dosemeters with an accuracy of +/- 5 to 15%, provided that correction factors are applied based on the generating potential or preferably the beam quality, expressed as half-value thickness.
