Cable feedthrough for radioactive environments

A vessel for containing a radioactive material, the vessel comprising:

• a feedthrough for shielding against the radioactive radiation, the feedthrough comprising:
• a plurality of electrical feedthrough conductors;
• a tubular metal housing, which is a tubular housing, including a plurality of ends and a plurality of seals, the plurality of ends respectively including a respective one of the plurality of seals so that an interior, which is hermetically enclosed, is formed in the tubular housing between the plurality of seals, the plurality of seals respectively including at least one insulating body through which at least one of the plurality of electrical feedthrough conductors is fed so that the at least one of the plurality of electrical feedthrough conductors is fixed in the plurality of seals respectively while being electrically insulated from the tubular housing;
• at least one connecting conductor extending in the interior, the at least one connecting conductor connecting at least one of the plurality of electrical feedthrough conductors at one of the plurality of seals to at least one of the plurality of electrical feedthrough conductors at another of the plurality of seals;
• and
• a plurality of shielding bodies, each of which respectively includes at least one opening, the plurality of shielding bodies being arranged successively in an axial direction of the tubular housing, the at least one connecting conductor being fed through the at least one opening, each shielding body being formed as a plate and including at least one of a material suitable for moderating a plurality of neutrons, a material suitable for capturing a plurality of neutrons, and a material suitable for absorbing a plurality of gamma rays, and respective ones of the plurality of shielding bodies neighboring one another in the axial direction and being made of different materials from one another.
