A recently developed source of intermediate energy neutrons was used to calibrate two commercial versions of the Andersson-Braun wide-range rem-response survey meter and a standard de Pangher long counter. The source, which emits a broad spectrum of neutrons centred on 0.5 keV, allowed an investigation of the response of these instruments in a hitherto unexplored energy region. The survey instruments were shown to be oversensitive to these neutrons, whereas the sensitivity of the long counter was shown to be relatively energy independent.
