An indirect method to infer the spectra, based on the measurement of the beam intensity transmission through different metallic samples, is described in this communication. A Plasma Focus device (5.67 kJ, 30 kV) was studied as a pulsed hard x ray source, operated with deuterium at a filling pressure in the range of 3 to 5 mbar. Relevant spectral components belonging to the 50 - 150 keV range with a single maximum located in the 75 - 85 keV region were obtained for the radiation coming out of the Plasma Focus chamber, which is made of stainless steel.
