In order to measure neutron flux and neutron energy distribution under high intensity gamma-ray background, we tried to reduce the efficiency for a gamma-ray with our original nuclear emulsion by falling in development temperature whereas keeping efficiency for a neutron. The emulsion was irradiated by neutron and gamma-ray, and developed with Developer for Opera Experiment at temperatures of 10, 15 and 20 oC. As a result, the efficiency for gamma was successfully reduced with keeping the efficiency for a neutron, but tiny fog increased with increasing developing time using Developer for Opera Experiment.
