Radiation Effects Association has carried out radiation epidemiological study for nuclear industry workers during 1990-2010. We assembled a cohort of 204,103 workers. The average cumulative dose was 13.8 mSv (median 1.0 mSv, interquartile range (IQR) 0.0-10.7 mSv) and the average follow-up period was 14.2 year. The present report has not concluded that low-dose radiation increases cancer mortality based on the follow-up data through 2010. One reason is that analyses among 75,442 respondents― the average cumulative dose was 25.8 mSv (median 6.3 mSv, IQR 0.2-28.0 mSv) and the average follow-up period was 8.3 year―to the lifestyle surveys revealed the decrease of the ERR after adjusting for smoking habits or educational year, suggesting that confounder has a large effect on the association between radiation exposure and mortalities in the cohort. Another reason is that in analyses on all cohort members, no significant ERR was observed in all death, and leukemia excluding chronic lymphoid leukemia. Significant ERR was seen in all cancers excluding leukemia, but this significance of the ERR might be affected by confounder such as smoking, because the significance of the ERR in all cancers excluding leukemia originates in the significance of the ERR in lung cancer.

We examined the relation of serum uric acid to mortality among 49,412 male employees aged 25 to 60 years old. Baseline data were collected during the health examinations performed between 1975 and 1982. Vital status was followed until 1985. Compared with men showing a uric acid level of 5.0-6.4 mg/dl, those with a level of 8.5 mg/dl and over had a 1.74-fold higher rate of mortality from all causes (p<0.05). Compared with men showing a uric acid level of 5.0-6.4 mg/dl, those with a level of 8.5 mg/dl and over had a 2.6-fold higher rate of mortality from cerebrovascular disease (p<0.01),1.7-fold higher rate of mortality from ischemic heart disease,3.1-fold higher rate of mortality from other heart disease (p<0.001),3.5-fold higher rate from liver disease (p<0.01), and a 7.0-fold higher rate from renal failure (p<0.01), respectively. Strong associations were obsereved between serum uric acid level and mortality from all causes, heart disease, cerebrovascular disease, liver disease, and renal failure. Associations was also observed between serum uric acid level and body mass index, systolic and diastolic blood pressure, liver function, serum total protein, serum total cholesterol, previous history of gout and circulatory diseases (p<0.001). Further investigation into the possible role of uric acid in the development of various disease is needed.
