Nuclear emulsion is used as charged particle detector in many directions, and stabilization of their long-term characteristics is required for many measurements. Especially in the field of cosmic ray radiography. Focusing on the composition of the nuclear emulsion, we found chemicals are improve the characteristics of long term stability.
