In an essay addressed to his colleagues, Japanese doctor Shigeru Mita has explained why he recently moved away from Tokyo to restart his practice in western Japan: He believes that Tokyo is no longer safe to inhabit due to radioactive contamination caused by the March 11, 2011, meltdowns at the Fukushima Daiichi nuclear plant.
The essay, titled “Why did I leave Tokyo?” was published in the newsletter of the Association of Doctors in Kodaira, metropolitan Tokyo.
Soil tests prove contamination
Dr. Mita opens his essay by contextualizing his decision to leave, noting that he had a long history as a doctor in Tokyo.
“I closed the clinic in March 2014, which had served the community of Kodaira for more than 50 years, since my father’s generation, and I have started a new Mita clinic in Okayama-city on April 21,” he wrote.
Dr. Mita notes that, for the past 10 years, he had been working to persuade the municipal government of Tokyo to stock iodine pills to distribute to the population in the case of a nuclear accident. Dr. Mita’s concern had been that an earthquake might trigger a meltdown at the Hamaoka nuclear power plant. All of his requests were rejected, however, under the excuse that there was no reason to expect such an accident.
When the disaster did occur — albeit at a different plant than Dr. Mita had feared — Tokyo did not act to protect its population, and still has taken no measures. Yet, based on soil surveys, Dr. Mita noted, “It is clear that Eastern Japan and Metropolitan Tokyo have been contaminated with radiation.”
Dr. Mita compares radioactive contamination of the soil (measured in becquerels per kilogram, Bq/kg) in various parts of Tokyo with that observed in various portions of Europe following the Chernobyl disaster.
Prior to 2011, Shinjuku (the region of Tokyo that houses the municipal government) tested at only 0.5-1.5 Bq/kg. Today, levels at nearby Kodaira are at 200-300 Bq/kg.
“Within the 23 districts of Metropolitan Tokyo, contamination in the east part is 1000-4000 Bq/kg and the west part is 300-1000 Bq/kg,” Dr. Mita wrote.
For comparison, Kiev (capital of the Ukraine) has soil tested at 500 Bq/kg (Cs-137 only). Following the Chernobyl accident, West Germany and Italy reported levels of 90-100 Bq/kg, and both experienced measurable health effects on their populations.
Dr. Mita notes that the radiation situation in Tokyo is getting worse, not better, due to urban practices of concentrating solid waste in small areas such as municipal dumps and sewage plants. That is why, he says, radiation levels in Tokyo riverbeds have actually been increasing over the prior two years.
“Tokyo should no longer be inhabited, and… those who insist on living in Tokyo must take regular breaks in safer areas,” Dr. Mita writes. “Issues such as depopulation and state decline continue to burden the lives of second and third generation Ukrainians and Belarusians today, and I fear that this may be the future of Eastern Japan.”
Patients showing radiation-induced sickness
Dr. Mita’s essay also chronicles the many cases he has observed of patients presenting with radiation-induced health problems. He notes that, since 2011, he has observed while blood cell counts declining in children under the age of 10, including in children under one year old. In all of these cases, symptoms typically improve if the children move to western Japan. He has similarly observed persistent respiratory symptoms that improve in patients who move away.
Other patients have shown symptoms including “nosebleed, hair loss, lack of energy, subcutaneous bleeding, visible urinary hemorrhage, skin inflammations, coughs and various other non-specific symptoms.” He also notes high occurrences of rheumatic muscle symptoms similar to those observed following the Chernobyl disaster.
“Ever since 3.11, everybody living in Eastern Japan including Tokyo is a victim, and everybody is involved,” he wrote.
