[Effect of x-ray spectrum transformation on bone marrow dose].

A study was made of change of the spectrum (spectral transformation) of x-ray radiation while passing through the soft tissue. Thirty-two depth spectra computed by the Monte-Carlo method and 16 experimentally measured spectra including 9 depth spectra taken from literature, were analysed. A method of the calculation of an absorbed dose in the red bone marrow with account of spectral transformation was described.
