Abstract：
The dose equivalent of neutrons from intermediate energy heavy ion reactions measured with a rem-meter would be underestimated because of the energy response of the instrument. Therefore the readings of rem-meter must be corrected in order to obtain the real dose equivalent The correction factors for dose equivalent ofneutrons from the reactions of 41.7MeV/u ¹²C+Fe and 100MeV/u ¹²C+C measured inside . shielding with both rem-meters the 10 in. diameter single-sphere rem-meter and the standard A-B rem-meter have been calculated. They could be applied in dose equivalent measurement for intermediate energy heavy ion reactions.
