Three kinds of video materials on the radioactive material leak accident which happened in J-PARC on May 23, 2013 have been produced. These have been screened on the "J-PARC Safety Day" to encourage the J-PARC staff members to keep the memory, to pass on the lessons learned to the next generation, and to use them for future safety.
