| Abstract: | The pulse height spectra of the radiation qualities of the low air-kerma rate, narrow-spectrum, wide-spectrum and high air-kerma rate ISO series, the A-, B- and C-series according to the German DIN standard 6818-1, several diagnostic and therapy radiation qualities and unfiltered X-ray spectra were measured using a Ge spectrometer and a special experimental set-up. The spectra were unfolded to obtain the fluence spectra. The values for the characteristic parameters (first and second half-value layer, mean photon energy, 10% percentile, kerma factor, conversion coefficients from air kerma, Ka, to the operational radiation protection quantities Hp(10), Hp(0,07), H*(10) and H'(0,07, ) rΩ ) were determined for each radiation quality and each unfiltered X-ray spectrum using these fluence spectra. All data given are normalised to reference conditions. For each radiation quality and each unfiltered X-ray spectrum the fluence spectrum is shown in a graph together with two other curves. One curve is the fluence spectrum weighted with the energy-dependent kerma factors; the second is the fluence spectrum weighted with the energy-dependent conversion coefficients from fluence to personal dose equivalent, Hp(10). |
