Abstract
A radiogenic unit includes an X-ray tube having an anode disposed at a first end thereof and a cathode disposed at a second end thereof, a high-voltage supply circuit which supplies power to the X-ray tube in single pole mode and which includes a heating transformer for the cathode, and a casing. The casing includes first and second parts imperviously sealed against fluids and X-rays and hermetically sealed to one another. The first part is made of an electrically insulating material, has a first cavity formed therein in which is housed the X-ray tube, and houses a conductive element for the anode. The second part is made of an electrically insulating material and has additional cavities formed therein in which are housed the high-voltage supply circuit. Preferably, the X-ray tube is shielded by three cylinders of different potentials.
