The neutron sources available at NBS for use in neutron dosimetry are described in terms of fluence, beam size, and background contamination. Operational details and neutron fluence monitoring of the recently installed standardized beam line of the 3-MV Van de Graaff Laboratory are given for the 200 keV to 1 MeV energy region along with plans for measurements at 14 MeV. Measurements of the response of typical laboratory dose rate meters and films to monoenergetic neutrons of accurately known fluence in the 250 keV to 1 MeV energy region are given. The problem of the neutron fluence to dose equivalent conversion is discussed. 11 figures, 2 tables.
