Abstract

X-ray spectra from a single-flash x-ray generator were determined by means of attenuation analysis using a new type of function fitting the bremsstrahlung spectra of the flash x-rays. These attenuation data were obtained by using a set of aluminum steps positioned at 1m from the source, while the x-ray detectors were the elements of a thermoluminescence dosimeter (TLD) which were placed behind the steps. The relative response function of the TLD element was also determined by using attenua-tion data achieved with the conventional hot cathode x-ray spectra measured with a spectrometer utilizing a lithium-drifted silicon detector. The flash x-ray generator was a single high-intensity type utilizing a hot cathode radiation tube used for biomedical radiography. This generator may be used for condenser charging voltages of less than 120kV; the pulse widths of the flash x-rays were less than 100ns. The peak intensities of the flash x-ray spectra tended to shift to the high energy region according to increases in the charging voltage and insertion of aluminum filters. The energy latitude of the flash x-ray spectra were wide compared to those obtained using a conventional x-ray generator used for medical radiography.
