In per se known manner, this apparatus comprises a radioactive source locked within a cylindrical source holder, which is itself fitted in an appropriate cylindrical recess. The cylindrical recess is higher than a larger diameter cylindrical recess, in whose walls are partly fitted at least one locking ring and at least one lug. The source holder has in its lower part a flange, whose upper portion is chamfered, as well as an annular groove and at least one slot, inclined with respect to the axis of revolution of the source holder and whose width is at least equal to the diameter of the said lug. This slot, which issues onto the upper face of the flange, is such that the position of the lug in the bottom of the slot corresponds to that of the locking ring in the annular groove. The apparatus has particular application to cobalt therapy equipment, particularly to the ALCYON head.

Device for storing a source of photons and for irradiating a body by the

An irradiation apparatus for obtaining an irradiation beam having precise and easily adjustable dimensions. This apparatus comprises more particularly a secondary collimation device having an axis Y--Y, removably fixed to the mobile arm of the irradiation apparatus and comprising a conical pot, two pairs of frames which support collimating plates and are movable about shafts fixed to said conical pot, each of said frames being connected to said conical pot by means of a compass system formed from legs hinged together about shafts. With said frames are associated mobile antipenumbra plates whose position is checked by means of a feeler system.
