An irradiation head permitting the positioning of the area to be treated and the checking of this position. This irradiation head, which is disposed downstream of the neutron target, is provided which a turret carried by a supporting plate and which can rotate about an axis zz perpendicular to said plate. The supporting plate has a central opening A of axis ZZ coinciding with the axis of the useful neutron beam and the axis of the collimator. The turret has three openings a1, a2, a3 which can successively face the opening A in accordance with the axis ZZ. Two of the openings a1, a2 are respectively associated with a light source S1 and an X-ray source S2 emitting beams of mean paths f1 and f2 equidistant with respect to axis zz, these beams being respectively designed for the positioning of the area to be treated and the checking of this position. |
