No discernible increase in cancer rates for workers.

No impact on birth defects/hereditary effects.

Theoretical increased risk of thyroid cancer among most exposed children.

It also undertook to make all the material available in Japanese. In an effort to make its work as widely accessible as possible to the Japanese population, the secretariat and experts of the Committee held several townhall meetings and events in Japan (Aizuwakamatsu, Fukushima, Koriyama, Iwaki, Minamisoma and Tokyo), and met with community leaders, teachers, city officials etc., to explain the findings and impact of its 2013 Report and White Papers. The findings remain broadly robust within their inherent uncertainties. The results of these reviews generally confirmed the assumptions and findings of the UNSCEAR 2013 Report.

Three White Papers ( 2015, 2016, 2017) were published after periodic reviews and evaluations of the implications of new scientific developments for the findings of the report. In the period between the UNSCEAR 2013 and UNSCEAR 2020/2021 Reports, the Committee put in place arrangements for follow-up activities to enable it to remain abreast of additional information as it was published in the scientific literature. Overall, the UNSCEAR 2020/2021 Report broadly confirms the major findings and conclusions of the UNSCEAR 2013 Report. The UNSCEAR 2020/2021 Report summarizes all of the relevant scientific information available (up to the end of 2019) relating to the levels and effects of radiation exposure due to the accident at the FDNPS.

Hence, the Committee embarked on a two-year project to update the UNSCEAR 2013 Report. At its sixty-fifth session (2018), the Committee decided to update the 2013 Report to reflect the latest cumulative scientific findings and developments.

The main findings of the UNSCEAR 2013 Report titled "Levels and effects of radiation exposure due to the nuclear accident after the 2011 great east-Japan earthquake and tsunami" were reported to the General Assembly in October 2013 (A/68/46), and the report was published in April 2014, along with the supporting scientific data and evaluation.Īs more information became available with time, there was increasing evidence that some of the doses to the public set out in the 2013 Fukushima Report were overestimated, with those from ingestion significantly so. In May 2011, the Committee embarked upon a two-year assessment of the levels and effects of radiation exposure from the accident. Radioactive material was released from the damaged plant and tens of thousands of people were evacuated. It was the largest civilian nuclear accident since the Chernobyl accident in 1986. On 11 March 2011, the Fukushima-Daiichi nuclear power station (FDNPS) suffered major damage after the magnitude 9.0 great east-Japan earthquake and subsequent tsunami.
