摘要

An irradiation facility designed to subject various objects or products to the action of ionizing radiation, which includes operating rooms, in which all the operations prior to and after irradiation are carried out and concerning the products or objects to be treated, maneuvering and control rooms of the sources and an irradiation chamber, a well full of water being open in the latter's soil, which serves for the conservation of the sources outside the work periods, characterized in that the radioactive sources have a support, whose vertical translation, from a high service position located outside the well, to a low conservation position located at the bottom of the well, is controlled by a cable, from which a certain length is rolled at one end on a drum , to which said end is fixed, the rotation of this drum by an electromagnetic brake being normally impeded, so that it is The end then constitutes a fixed point and the cable can fulfill its function of controlling said translation, the brake being able to loosen when an incident occurs in the operation of the irradiator, which has the effect of releasing said length of cable, thus causing the relatively slow fall of said support to the bottom of the well.
