The long-range delta electrons carrying off part of the energy lost by secondary electrons in the operating chamber should be considered in measuring the photon beam intensity in high-energy ionization chambers. Formulas are derived for determining the photon beam. Considerations of long-range delta electrons in calculations of 260-Mev synchrotron bremsstrahlung altered the absolute sensitivity value of a thick-walled graphite chamber (T = 4.5 cm) by 2% and increased by 12% the absolute intensity magnitude measured with a thin-walled chamber by the couple difference method.
