Formulae expressing the continuous spectra of x-rays radiated from a capacitor type x-ray apparatus with an inductance in the x-ray tube circuit are introduced and some calculated examples are shown. Continuous spectra radiated from a capacitor type apparatus having no additional impedance in the x-ray tube circuit, and a capacitor type apparatus with a protective resistance in the circuit and a wave tail chopping device are also calculated as references. (1) The continuous spectra radiated from an apparatus with an inductance lack the high photon energy portion which are contained in the ones from an apparatus without the inductance. (2) The continuous spectra radiated from an apparatus with a protective resistance and a wave tail chopping device have less energy fluence in the low photon energy region than the ones from the apparatus without the wave tail chopping device.
