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 dollars in 2005. (2) Economic scale of RI utilization in agriculture is 4M dollars for R&D, 127M dollars for environmental protection and 1M dollars for chronology. A total sum is 132M dollars for 2005 and 24M dollars for 1997. RI usage in agriculture is increased 5 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 8,432M dollars.
