Great earthquake in eastern JapanTen years have passed since then.TEPCO Fukushima Daiichi nuclear power plant10 years have passed since the accident occurred. I will never forget the tension at the time of the accident, that I was watching the transition with a sigh.
United Nations Scientific Committee report that “the health effects of radiation exposure are small”
Over the past 10 years, on-site decommissioning work has been carried out and last month at Unit 3 the extraction of nuclear fuel from the spent fuel pool was completed. I would like to express my sincere respect and gratitude to those who worked on it. However, it is difficult to recover the melted fuel debris and it is unknown when the work will be completed in the future. Even after 10 years, it is still unclear how many stations the process has gone to until decommissioning. Once again, I feel the magnitude of the impact of the nuclear accident.
Meanwhile, the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) has published the latest report on the effects of this accident. There are two main points.
(1) Fukushima residents have not been informed of the increase in cancer development due to the effects of radiation exposure, and the cancer is unlikely to increase in the future.
(2) The increase in the number of thyroid cancer diagnoses (or “suspects”) in tests conducted by Fukushima prefecture for children under the age of 18 at the time of the accident is not due to the effects of exposure, but at high precision. Probably the result of a screening test
UNSCEAR said in a previous 2013 report that there was no health hazard from radiation exposure. In this report, as a result of incorporating the latest findings and re-estimating the exposure level of Fukushima residents, the exposure dose has been significantly revised downward.
UNSCEAR is an organization established on the basis of the 1955 UN General Assembly resolution amid growing concern over the environmental and health effects of radioactive fallout as a result of repeated atmospheric nuclear tests in the great powers of the United States. fifties. In addition to the Three Mile Island Nuclear Power Plant Accident (1979) and the Chernobyl Nuclear Power Plant Accident (1986), the report also summarizes the effects of radiation on the human body in medical treatments such as examinations. by TC. The report will also be the basis for ICRP (International Commission on Radiological Protection) recommendations, IAEA (International Atomic Energy Agency) guidelines and the laws of each country, including Japan. It is considered the most authoritative and trusted international organization for radiation exposure.
According to an interview article (Asahi Shimbun Digital dated March 9, 2018, SYNODOS dated May 12, 2018) with former UNSCEAR Japan Representative Shingon Akashi, Professor of Radiological Emergency Medicine (Radiation Medicine), The committee said: “Science, not Experts from around the world participate on the basis of the principle of” independent policy and imparts “(” a position based on science, independent and equitable policy “). Japan to maintain objectivity.
As a result, it is good news that we concluded like this time. I hope that the content of the report will be communicated to people across the country, the prejudice against Fukushima that still remains in part will be removed and the damage caused by the rumors will disappear.
