Abstract: The total bremsstrahlung (BS) generated in compounds of BaCl₂.2H₂ O, CuCl₂: 2H₂O, Pb(CH₃ COO)₂.3H₂O, PbCl₂, Pb(NO₃)₂, and CuSO₄.5H₂ O by ⁹⁰Sr was investigated using a Si(Li) detector to determine the dependence of the BS spectra on the modified atomic number (Z_mod) of compounds in the photon energy range of 1-100 keV. A continuous decrease in the Z_mod dependence of the bremsstrahlung spectra in the energy range of 1-30 keV was observed, followed by a slow increase thereafter, i.e. in the range of 30-100 keV. The stronger Z_mod dependence of the spectra at low photon energy was expected to be the result of the high intensity of polarization bremsstrahlung (PB) at low photon energy, increased interference of ordinary bremsstrahlung and PB, and interference by bremsstrahlung from different atoms of the compounds in these compounds.
