Abstract

A detector of penetrating radiation, in particular x-radiation, comprises a photoconductive material 2 to which two electrical signals f0 and f1 are applied, and an output signal is detected and in the presence of radiation incident on the detector this includes a component formed by mixing of the two input signals. This component can be an harmonic if the two signals are of the same frequency. The amplitude of that component is proportional to the intensity of the incident radiation. There is also a background component which should either be reduced to insignificant proportions or removed. Advantageous electrode arrangements for such a device are also disclosed. <IMAGE>
