Tighter regulation of industry’s disaster preparedness required

what realistically their health risks are, what they can do to protect themselves and their children.”

On the ground research informs these recommendations. The Mailman School led the first epidemiological study of the 1979 Three Mile Island accident, which found no increased cancer risk among those living near the plant. Today, Dr. Kleiman is doing studies of workers who cleaned up the 1986 Chernobyl accident, who endured much greater radiation exposures. With Fukushima, he said, “there is an urgent need to use this experience in a positive way to better estimate what the low-dose risks are.”

While radiation risks are often misunderstood by the public, their anxieties are real and can have serious health consequences. Dr. Kleiman cited a report from the World Health Organization showing that by far the biggest health issue from the Chernobyl disaster wasn’t cancer but mental health issues like depression and anxiety. In some instances, this leads to physical symptoms, including, in extreme cases, nausea, vomiting, and diarrhea, that are identical to what would happen with exposure to high levels of radiation.  To address this challenge, Dr. Kleiman and his colleagues at the Columbia Center for Radiological Research are developing methods to quickly identify who has been exposed to radiation and by how much to determine appropriate ways to treat both physical effects and emotional fall-out.

As the recovery continues in Japan, the goal is a return to normalcy. A big challenge will be finding homes for the approximately 160,000 who remain displaced. Shelters can, unfortunately, become semi-permanent for some, said Dr. Garfield, who is also the Henrik H. Bendixen Professor of Clinical International Nursing, at Columbia School of Nursing. He notes that even today, some Japanese in the south remain displaced from the 1995 Kobe earthquake.

Another major issue facing the country is energy. Before last year’s disaster, fifty-four reactors provided 30 percent of Japan’s electricity. Today only two are operational, and they are scheduled to go offline by early May. This represents a major shift for Japan, which has long embraced nuclear technology. The ongoing energy shortage may also pose a health risks, said Dr. Garfield, especially for the elderly, because of restrictions on summer air conditioning.

While the experience of Fukushima has soured the Japanese on nuclear energy, others continue to embrace it. China and India have a number of reactors in the works and, in February, regulators in the United States gave the go-ahead on the first new reactors in this country since 1978.

On 5 March, Dr. Redlener participated in a discussion with experts from Japan and the United States on the issue of nuclear power in the context of recertifying the 37-year-old Indian Point reactor, which is located only thirty-five miles from New York City. “This aging plant is located in a very population-dense region. A major disaster here would have even greater consequences than were seen at Fukushima. To make matters worse, the plans for evacuation and response to a major accident are seriously flawed,” said Dr. Redlener. He points to his experience with the 2010 oil spill in the Gulf Coast, where he saw a serious absence of leadership and coordinated response. As with Fukushima and TEPCO, there was a “dangerous defaulting of safety and response responsibilities to industry,” without much regulatory oversight. Compounding the problem are budget cuts: recent years have seen 17 percent less money for disaster preparedness in general. “We can do better,” Dr. Redlener said.

Even with a committed government, Dr. Redlener stressed that good disaster response also depends on citizens themselves being prepared for the unexpected. “In any large-scale disaster, it’s worth remembering that you are your own first responder.”
