Determining fast-neutron flux density by radioactivation of uranium-238

Book ·
OSTI ID:6904813
This method covers procedures for determining fast-neutron flux density, neutrons.cm/sup -2/.s/sup -1/, by assaying a fission product (F.P.) from the fission reaction /sup 238/U (n,f)F.P. The reaction is useful for measuring neutrons with energies from approximately 1.5 to 7 MeV and for irradiation times up to 30 to 40 years.
