The economic scale of radiological technology in medicine/dentistry in 2005 was about 13 billion dollars. Economic scale of medical/dental cares in 2005 was large to the magnitude of 17% than that in 1997. It is worthy of mentioning that almost radiological items used in medical/dental cares were increased except a radioisotope examination in medical care. Namely, radioisotope examination was 1.7 million dollars in 1997 but was 0.4 million dollars in 2005. No radioisotopes were used in the examination of dentist.
