In the statement of Environmental Radioactivity and Health
issued in March 29, 2011, we strongly recommended that
People living in the effected areas should regularly take
antioxidant supplements such as vitamin C to counteract the
negative consequences of long-term low dose radiation
exposure as well as to protect the health of coming
generations. However, TEPCO, government and all medias
ignored our statement.
Recently, we examined cancer-related gene expression in 16
men who had worked at severe radiation environment at
Fukushima nuclear plant. We also confirmed the improvement
of cancer risk score by the supplementation of Vitamin C and
other anti-oxidative nutrition.

(1)  We evaluated the effects of radiation exposure on cancer
related gene expression in 17 men who worked 5-6 weeks at
the radiation contaminated area of Fukushima nuclear plant.
(2)  After working, plasma free DNA was increased in 2 of 13
workers, and cancer risk score was increased in 3. After the
2 months intervention with intravenous Vitamin C and oral
anti-oxidative nutritional supplements, free DNA returned to
normal level and cancer risk score was significantly
decreased (p<0.05).
(3)  No significant change was seen in 4 workers who took once
i.v. Vitamin C at before working and continuous intake of
anti-oxidative supplements during the working period. (4)  Increase in cancer risk by radiation exposure can be
protected by anti-oxidative nutritional intervention.
Fukushima workers in the radiation contaminated area
should take anti-oxidative nutrition therapy immediately. 37
