Abstract
For the study of radio-enhancement effect with Ag and Sm in biological matter at kilovoltage X-ray the quantitative estimation was executed by determining a parameter DEF (dose enhancement factor). The necessary for DEF calculations X-ray tube (45 kVp, with the Cu anode) radiation spectrum is modeled depends on its design and technical parameters. The use of filters for X-ray tube spectrum can increase the DEF value. For calculated X-ray spectra DEF values linearly grow at increasing of the fractions of Ag and Sm elements in the soft tissue. This research clarifies the physical reasons that led to the choice of these elements as targets for X-ray radiation, with an energy range where the photoelectric effect is predominant.
