Claim:
1. An observation instrument inside a thick-walled radiation shielded cell, wherein the instrument is arranged to be capable of extending inside a cavity passing through a wall of the cell, the instrument comprising two separate modules: a first module of the instrument comprising a biological protection shield, a camera for acquiring images of zones situated in the cell; and a travel mechanism for moving the camera between a retracted position to which the camera is retracted into the cavity and a deployed position for observing the inside of the cell, the travel mechanism being coupled to the camera and including an actuator for causing the camera to move between the retracted position and the deployed position; and a second module of the instrument comprising a dome that is substantially transparent to rays or radiation and that is arranged to be capable of receiving the camera therein when the camera is in the deployed position for observation; each of the two modules including a mutual bearing face, the two modules being capable of being put into mutual contact via their respective mutual bearing faces when the modules are engaged in the cavity, the camera being arranged between the dome and the shield, and being secured to the shield via the travel mechanism the dome being provided at a first end of the instrument the actuator causing the camera to move between the retracted position away from the dome and the deployed position in which the camera extends inside the dome, the travel mechanism being arranged between the dome and the shield, and the dome being separate from the camera, from travel mechanism, and from the shield of the instrument.
