A transmission-type ionization chamber for monitoring dose power of the Roentgen-TA 150/10 X-ray therapeutic apparatus is described. The X-ray working dose range of the apparatus is 4.5-70 keV. The X-ray chamber sensitivity at Al equivalent 100 nm for X-ray energy 4.5 keV is 2·10 -11 A/mGy/sec. Relative spectral sensitivity error of the chamber within the given range is ±13.0 %. The correction of the apparatus reduces this error to ±3. 0 %. © 2012 Springer Science+Business Media, Inc. Source
