Calcul des conditions optimales en analyse par activation

The calculation concerns to the following three parameters; the duration of the irradiation, the time elapsed between the end of the irradiation and the radioactivity measurement, and the duration of the activity measurement. The calculation is carried out in two different ways thus either the sensibility or the maximum precision can be obtained. The optimum values of the studied variables are plotted against the simple parameter in the cases when the ground noise is produced by a single component and the radioactivity originates from one isotope. The values of the variables corresponding the optimum, about 10% precision and sensibility are also given. These values make possible to reduce significantly the time required for the analysis.
