Fast neutron flux (14.8 MeV) of a neutron generator has been measured by activation technique. The measurements performed using Cu and Ni threshold detectors. 62Cu and 57Ni were produced through 63Cu (n, 2n) 62Cu and 58Ni (n, 2n)57Ni reactions. They decay by emitting 511 keV and 1377 keV gamma rays, respectively. The half life of 62Cu is 9.74min and that of 57 Ni is 36 hours. The flux of neutron has been calculated by measuring the activity after the irradiation time. Gamma spectroscopy of the activated foils was performed using a HPGe detector. By employing this technique the neutron flux of 2.64×107±3%n/s was obtained for 60 μΑ deuteron of 110 keV energy, bombarding a solid target of 3H.
