Cosmic-ray radiography is non-destructive inspection for large structures. Nuclear emulsion detectors can install almost everywhere because they have features such as flexible shape and size, light weight, no power supply, and water/dustproof. In high radiation environment, however, accumulation of noise (tracks of environmental radiation) may be problems for analysis. This study evaluated noise that accumulated in nuclear emulsion which installed in locations with different radiation dose.
