Three reactors at the Fukushima Daiichi nuclear plant melted after a magnitude 9.0 earthquake and tsunami hit on March 11, 2011, releasing massive amounts of radiation in. We also summarize the recent increased incidence in thyroid cancer in the Fukushima area following the accident in relation to increased thyroid ultrasound screening and the use of advanced ultrasound techniques. The ruling was the first by the top court on government responsibility for the Fukushima disaster in four compensation lawsuits filed by about 3,700 Fukushima residents. Thus, although the dose of radiation was much lower, the incidence of thyroid cancer appears to be much higher than that following the Chernobyl accident.Ī comparison of the thyroidal consequences following the Fukushima and Chernobyl nuclear reactor accidents is discussed. ![]() The Japan Center for Economic Research, a private. To date, screening of more than 280 000 children has resulted in the diagnosis of thyroid cancer in 90 children (approximate incidence, 313 per million). In 2016 the government increased its cost estimate to about 75.7 billion, part of the overall Fukushima disaster price tag of 202.5 billion. Because the incidence of childhood thyroid cancer increased in those residing near the site following the Chernobyl accident, thyroid screening of all children (0-18 years old) in the Fukushima Prefecture was started. Therefore, thyroid radiation doses were less than 100 mSv (intervention levels for stable iodine administration) in the majority of children, including less than 1 year olds, living in the evacuation areas. The signs were unmistakable that the feared meltdown had begun. The director of the power plant immediately forbade anyone from entering the Unit 1 building. Residents near the FDNPS were evacuated within a few days and foodstuffs were controlled within 1 or 2 weeks. The pressure on the steel containment vessel enclosing the reactor holding the nuclear fuel was about to exceed the permissible values. ![]() The amount of radioiodine released to the environment following the Fukushima accident was 120 Peta Becquerel, which is approximately one-tenth of that in the Chernobyl accident. This is a summary of the nuclear accident at the Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Stations (FDNPS) on 11 March 2011 to be used as a review of the radiation effects to the thyroid and strategies of prevention. IAEA with a copy of a report on the discharge record and the seawater monitoring results at the Fukushima Daiichi Nuclear Power Station during March.
