(managed by NIBB)

Head of Facility:
Takashi Horiuchi
Technical Staffs:
Kazuhiko Furukawa (Radiation Protection Supervisor)
Yosuke Kato
Yoshimi Matsuda (Radiation Protection Supervisor)
The facility is composed of a main center and two subcenters, one in the NIBB and the other in the NIPS. The facility is being used for molecular analyses of organisms. A laboratory facility for recombinant DNA research is installed in the center. The subcenter in the NIBB is also equipped with a recombinant DNA research laboratory. The members of the Radioisotope Facility maintain and control the center and subcenter, and provide users appropriate guidance for radioisotope handling.
