A dual-energy photon attenuation technique provides a means of measuring void fractions in a flowing fluid. The mean void fraction determined by this method is in dependent of the fluid thickness. A comparison of the dual-energy method with the single-energy attenuation technique reveals that the assumption of a static refer ence void fraction in a dynamic voiding case is less severe with the dual-energy method.
