Abstract : This patent provides a novel method and system for the detection of voids or other composition anomalies in wires and particularly in composite wires; which comprises a source of penetrating radiation, such as an X-ray, gamma or neutron source for irradiating the wire; a fluid bath in which the wire may be moved, the bath containing a material having a linear coefficient of attenuation for the radiation closely matching that of a standard or ideal composition wire; and a detector system for observing and comparing the transmission of the radiation through the bath and wire with that through the bath only, or through the bath and wire with that through the bath containing a normal or standard wire.
