The use of 14-Mev-neutron irradiation makes it possible to extend the field of application of activation analysis to elements which cannot be activated in nuclear reactors (oxygen, boron, for example) or else to consider the possibility of portable'' measurement units for routine analyses. With this aim, tests have been carried out for studying the sensitivity and interferences in the case of the dosing of oxygen in eleven different matrices using 150 and 300 kv SAMES accelerators producing 14-Mev neutrons by the reaction H/sup 3/ (d,n)He/sup 4/. The sensitivity of the dosage methods for six other elements has also been studied. The results obtained show that, for a neutron flux of 10/sup 10/ n/4 pi , the sensitivities vary from 100 mu g and 1 mg for oxygen in nine matrices (Be, Ta, Nb, Ti, Zr, Fe, Al, Sb, Si) and that it is possible to dose the six elements F, B, Y, Si, N, Al with sensitivities of between 1 and 1000 micrograms.
