BS>A theoretical evaluation is presented on the possibility of using an electron accelerator for the photoneutron determination of Be/sup 9/ in ores. It is demonstrated that the neutron yield is a linear function of the Be/sup 9/ concentration in the sample and the current strength at the target of the accelerator. An accelerator for approximates 2.7 Mev with a mean current in the beam of approximates 280 mu a (230 ma per pulse) with a tungsten target makes it possible to obtain up to 800 neutrons/ min at a approximates 2.10/sup -3/% concentration of BeO in the sample. A concentration of Be/sup 9/ in samples of up to 10/sup -5/% can therefore be measured with this installation to an accuracy equally as good as that of existing installations with radioactive sources. By using electron accelerators, the efficiency of photoneutron determirtations of Be/ sup 9/ can be increased by a factor of 20-40, the measuring error can be reduced from 50 to 3--5% at BeO concentrations of approximates 10/sup -3/% in the sample, and the safety of the attendant personnel can be reliably ensured.
