Abstract

Three methods were used to obtain dose distribution inside human body : experimental, semiempirical and numerical. The computer code was developed for calculations of dose equivalents in 23 organs of adult mathematical phantom for photon energies from 10 keV to 150 keV. The X-ray spectra were measured for 5 types of X-ray sets by using NaI (Tl), Si (Li) and Ge (Li) detectors. The organ doses and effective dose equivalents were determined for 47 types of X-ray diagnostic examinations. It was shown, that the estimated effective dose equivalent is 1.4 mSv/person-year due to medical irradiation for the population of the USSR.
