In order to measure neutron spectrum in high -ray field, a new nuclear emulsion and its data-processing system are developed. This report examined the optimal development conditions about the new nuclear emulsion NGITA (Neutron-Gamma Image TrAcker). By lowering developing solution temperature to 10 $^{circ}$ C from 20 $^{circ}$ C, the sensitivity to a ray was able to be controlled to the abbreviation 1/10, with the sensitivity to a neutron maintained.
