Abstract：
For the 10 inch diam. single-sphere rem-meter and the standard A-B rem-meter placed outside the concrete shielding wall, correction factors for measuring the high energy neutron dose equivalent produced by intermediate energy heavy ion reaction have been calculated taking into account the energe response of the rem-meter and the effect that the neutron spectra become remarkably "harder" after penetrating through a concrete shielding wall.
