1. A nucleonic instrument for measuring a density or level of one or more material phases within a container, comprising:
(a) an array of sources of ionising radiation, (b) at least one detector probe for detecting ionising radiation comprising an array of radiation detectors mounted on a circuit board, (c) a power source, and electronic apparatus comprising a control unit and a signal and data processing means for calculating a density profile of the material phases using signals generated by the detectors in response to radiation received from the radiation sources; the power source and electronic apparatus being housed within an enclosure supported mounted adjacent to the detector probe,characterised in that said circuit board comprises at least two portions each portion being aligned substantially parallel to the longitudinal axis of said array and each of said portions being in a different plane from each other portion.
