Cosmic rays below 100 MeV are key to the origin of life and the evolution of stars, and they activate interstellar matter to emit spectral emission lines of X-rays and gamma rays specific to the elements. In this research, we will establish an imaging method to visualize line X-ray gamma-rays from activated materials in general. We will expand this method to the fields of space, medicine, and pharmacology, and establish a new interdisciplinary framework for imaging “dynamics of materials” in a unified manner. We will make a breakthrough not only in space science but in particle therapy and pharmacokinetics of ultra-low concentration drugs to visualize their therapeutic effects.
