1. An electrical junction or circuit for use in radiology comprising:

  • a coating element of a layer of plastic material laden within or in which there is dispersed conductive particles, the coating element having an electrical resistivity of about 1 ohm-cm to about 100 kilohm-cm;

    wherein the coating element surrounds the electrical junction or circuit and is in electrical contact with the junction or circuit;

    wherein the plastic material is a polymer;

    wherein the conductive particles are selected from the group consisting essentially of a powder of stainless steel, a powder of aluminum, a powder of graphite, or combinations thereof; and

    wherein the coating element reduces an electric field density at a peripheral point of the junction or circuit having a voltage on the order of several tens of kilovolts thereby avoiding a breakdown between the point and ground potential.
