摘要： The invention relates to a method for producing a radioisotope, which method comprises irradiating a volume of radioisotope-precursor fluid contained in a sealed cell of a target using a beam of particles of a given current, which beam is produced by a particle accelerator. The target is cooled and the internal pressure in the sealed cell is measured. During the irradiation, the internal pressure (P) in the sealed cell is allowed to vary freely. The irradiation is interrupted or its intensity is reduced when the internal pressure (P) in the sealed cell departs from a first tolerated range defined depending on various parameters that influence the variation in the internal pressure in the sealed cell during the irradiation. These parameters for example comprise, for a given target, particle beam and radioisotope-precursor fluid: the degree of filling of the hermetic cell, the cooling power used to cool the given target, and the beam current (I). The invention also relates to an installation for implementing the method.
