In 1953, the United States detonated above­ground nuclear weapons during tests at the Nevada Test Site. In 2011, the Fukushima Daiichi meltdown occurred in Japan. Both events spread radioactive material over many miles and over population centers. Neither event resulted in any adverse health effects from that radiation.

But the response to the Fukushima event was disastrous because of the irrational and misinformed fear of radiation. That fear—not radiation—killed at least 1,600 people and destroyed the lives of at least another 200,000. That fear seriously harmed the entire economy of Japan, stopped cold the fishing industry and other agriculture in that area, and, overnight, reversed the country’s progress in addressing climate change.

The U.S. tests spread two to three times more radiation than did the events of Fukushima over the people of Utah, particularly the town of St. George. Like with Fukushima, no one was hurt, there was never any increase in cancer rates, and no one died as a result. But in Utah, the economy and people’s lives were unaffected. Why was there such a different result?

NASEM report: U.S. low-dose radiation research needs DOE/NIH leadership

June 3, 2022, 9:29AMNuclear News

A new report from the National Academies of Sciences, Engineering, and Medicine (NASEM) estimates that $100 million annually will be required for the next 15 years to develop a coordinated research program led by the Department of Energy and the National Institutes of Health to study how low doses of radiation affect disease risk. The recommended research would investigate causal links to specific health conditions and better define the impacts of radiation doses, dose rates, types of radiation, and exposure duration.

Meltdown: Drama disguised as a documentary

The cooling towers of Unit 2 at Three Mile Island Nuclear Generating Station, closed since the accident in 1979.

The Three Mile Island accident in 1979 was the most-studied nuclear reactor event in the U.S. There is a plethora of research about the accident available to the general public, including the president-appointed Kemeny Commission report and the Nuclear Regulatory Commission’s Rogovin inquiry report (split into volume one, and volume two, parts one, two, and three), which are the two detailed government-sponsored investigations into the accident. There are also thousands of documents in the NRC’s ADAMS database available to the public, an excellent overview by NRC historian Samuel Walker Three Mile Island: A Nuclear Crisis in Historical Perspective, as well as the Nuclear News special report from April 1979, and articles written by ANS members like William Burchill about the accident and the many changes it forced on the industry. If the producers of Meltdown: Three Mile Island—available on Netflix—had read any of those documents instead of relying mostly on input from antinuclear activists, their “documentary” might have been presented with at least some sense of balance and credibility.

Instead, similar to a recent Science Channel documentary on the Three Mile Island accident, Meltdown focuses on drama instead of science. This four-part miniseries does not attempt to provide a balanced set of facts from the technical community and instead relies heavily on nonexpert opinions and anecdotal statements to tell a story that easily falls apart under even the faintest scrutiny.

Nuclear News reached out to multiple ANS members who were involved with either the accident response or the clean up to help provide a critical look at some of the more egregious statements made in the documentary.

Medical company faces NRC fine for failing to secure sealed sources

February 22, 2022, 12:06PMNuclear News

The Nuclear Regulatory Commission has proposed a $7,000 fine to Marian Medical Services (MMS), of Wildwood, Mo., for four violations of regulatory requirements related to its licensed activities in Anchorage, Alaska. The violations involved the company’s failure to properly handle, store, and secure five sealed sources that it was licensed to use at its Anchorage medical clinic to perform diagnostic imaging services.

According to an NRC report, the clinic was licensed in 2016 but stopped offering nuclear medicine services in 2018 because there weren’t enough patients to sustain the business.
