Rem-meter correction factor for measuring high energy neutrons outside concrete shielding

Rem-meter correction factor for measuring high energy neutrons outside concrete shielding 1 first-author Institute of Modern Physics, the Chinese Academy of Sciences, Lanzhou 730000 Institute of Modern Physics, the Chinese Academy of Sciences, Lanzhou 730000 Correction factors of both Rem-meters, the 10 inch diameter single-sphere Remmeter and the standard A-B Rem-meter, were estimated for measuring high energy neutron dose equivalent outside a concrete shielding wall and the effects that the emitted neutron spectra become remarkably "harder" penetrated through a concrete shielding wall, and the energy response of the Rem-meter were taken in account. The estimated results could be applied in the measurement of neutron dose equivalent for the intermediate energy heavy ion reactions to avoid the difficulty induced by the energy response of the Rem-meters.
