title: Economic scale of utilization of radiation in medicine in Japan.
abstract: Economic scale of radioisotopes (RI) in Japan is studied in the field of medicine, agriculture and a part of industry. (1) RI is used during medical examination with economic scale by 1.7M$ (million dollars) in 1997 and 0.4M$ in 2005. (2) Economic scale of RI utilization in agriculture is 4M$ for R&D, 127M$ for environmental protection and 1M$ for chronology. RI usage in agriculture is increased five times due to needs at environmental technology lasted after the Kyoto protocol. (3) Indirect economic scale of RI ((85)Kr, (147)Pm, (90)Cr) usage in paper fabrication field in Japan for 2006 is 8432M$.
