Abstract
The NBS Thermal Neutron Flux has been calibrated in terms of the gold thermal neutron capture cross section. The effective thermal neutron (below cadmium cutoff energy) flux density is estimated to be 4307 ± 2 percent n/cm2 sec in September 1961. This figure is in agreement with a recent value quoted by the NBS.
