Gosniikhimfotoproyekt was developed special photographic materials for recording spectra in the vacuum ultraviolet UV region. Until now no data were available on the spectral sensitivity of photographic materials in the 20 to 100 nm range. Presented in the report are the results of determination of the absolute spectral sensitivity of photographic films developed by Gosniikhimfotoproyekt in the broad spectral region from 30 to 450 nm and the procedure of the measurement and the set-up employed in the work are described.
