More than 60 years ago this month – though not related to the holiday season as far as we know — a string of bulbs lit up courtesy of Argonne National Laboratory. What was the significance? The electricity used to power the bulbs was generated by an experimental breeder reactor and was the first electricity produced using the heat of nuclear fission.

REFRESH is an occasional series where we rerun previous posts. This first ran in December 2014.
The Advisory Committee on Reactor Safeguards is a statutory body of scientists, engineers and other experts in fields related to nuclear safety. The Committee conducts independent reviews of nuclear power plant applications and other matters referred to it by the NRC. It has a long history – its responsibilities were described in the Atomic Energy Act of 1954, as amended.
This group shot, taken from the 1989 Annual Report to Congress, shows the ACRS members as of September that year. The photo is timely as the committee held its 637th meeting last Thursday.
The Chairman is seated in the middle. TBT Quiz: What was the Chairman’s name and to what position would he be appointed just two months later? Extra points if you can name the vice chairman, seen here seated second from the left.

We’ve been writing in this series about radium—how it was discovered, how it was used, how it can impact human health. Today we want to explain where the NRC fits in.
As we said in our last post, the states originally oversaw radium use. In 2005, Congress gave the NRC authority over radium through the Energy Policy Act. In 2007, we put in place our regulations on the control, use, and disposal of radium. These rules made clear that the NRC oversees radium only after it has been purposely concentrated for use.
Because many states already had laws on radium, we took over regulatory oversight in phases. We had full oversight for radium in all states by August 2009 (either through states that regulate nuclear materials under agreements with the NRC, known as Agreement States, or directly in those states that remain under NRC jurisdiction).
In 2007 after our regulations were put in place, we began talking to the U.S. Navy about radium contamination at their sites. As we learned more about this program and talked with the other branches of the military, we began working to clarify our role in the remediation at military sites. During the same time, we became aware of two specific radium cleanup efforts by other federal agencies. The Environmental Protection Agency has done cleanup work at the former Waterbury Clock Company, in Waterbury, Conn. The National Park Service is also involved in a cleanup project at Great Kills Park, in Staten Island, N.Y.
As we learned more about these projects, it became apparent that a critical step for us to take would be identifying historical commercial radium sites; many of which were many decades old. As such, we began to look for sites in our jurisdiction that may have radium, and to find out how much, if any, cleanup was done. There are no known health and safety issues at any of these sites, but we want to make sure they do not pose a risk.
We contracted with Oak Ridge National Laboratory to help us develop a full picture of commercial radium sites. The lab started by cataloging the different products developed and sold to the public in the early 20th century. Oak Ridge scoured existing publicly available literature, records and databases, identified sites where radium may have been used to make consumer goods and looked for any cleanup records. We received the final results in November 2015.
We are working to get more information about the sites under NRC jurisdiction. We will be reaching out to site owners. Our goal is to confirm that these sites do not pose a risk to public health and safety and the environment. We’ll keep you posted on our progress.
Until 1945, radium was the best known radioactive material. It was widely found in consumer and medical products. And, as we saw in Part I of this series, it became notorious for fatally sickening radium watch-dial painters in the 1920s. With few exceptions, oversight of public and workplace safety for radium was mostly a state responsibility, and the federal government’s role was limited to such issues as preventing false advertising and regulating mail shipments.
At that time, radioisotopes came from just two limited sources. They were painstakingly isolated from natural ores, as was radium, or created in small batches in particle accelerators. These accelerators fire beams of electrons, protons and other particles at elements to create radioactive isotopes. Today the products of these two processes are called NARM—short for Naturally-Occurring and Accelerator-Produced Radioactive Material.
Scientists working on fission and the Manhattan Project discovered new radioactive isotopes with interesting properties. They soon became widely available to scientists, who found many uses for these products, from medical to basic research. They were under federal control and soon eclipsed the small amounts of radium and other NARM that existed before the war. Cold-War security concerns demanded federal control of nuclear technology and this new radioactive material.
Still, the 1946 Atomic Energy Act avoided intruding on state authority over NARM. It focused the Atomic Energy Commission’s oversight on fissionable material such as uranium and thorium and reactor-produced isotopes. The AEC controlled the vast majority of radioactive material.
This division of power didn’t disturb existing state authority but made little technical sense. An isotope produced in a reactor would be identical to one found in nature or produced in an accelerator. Moreover, state oversight was uneven.
Radium had lost its luster and fallen into disuse. Safer reactor-produced isotopes and sources with shorter half-lives mostly replaced radium for medical uses. Radium consumer products disappeared from stores by the 1970s. But products made with radium during its heyday (see Part I) retain their hazard for a long time.
So, from time to time, reports would emerge of products found in someone’s attic or office, or contamination found in a building. This prompted the Public Health Service to launch a program to collect and safely dispose of old radium sources.
Beginning in the late 1960s, state radiation control officers called for legislation to give the AEC and later the NRC the power to regulate radium and other NARM. In 1985 the NRC asked to be given authority over NARM waste disposal, but Congress took no action. The status quo remained, in part due to difficulties Congress had deciding on the federal agency best suited to regulate radium and oversee cleanup.
Little changed until the 1990s when terrorism provided a new dimension of concern. Experts worried that untracked or stolen radioactive sources, including radium, could be used in “dirty bombs.” Between 1998 and 2003, as part of the U.S. delegation to the International Atomic Energy Agency, the NRC worked with member nations on a code of conduct for radioactive sources. To limit the potential for “malicious acts,” the code appealed to each country to develop a national system of regulation for a list of radioactive sources — radium among them.
In the wake of 9/11, support for the IAEA code gained momentum. Congress included a provision in the 2005 Energy Policy Act giving NRC oversight of radium and other sources of NARM. A consensus for federal regulation emerged only when national security issues joined long-standing health concerns.
When Marie and Pierre Curie discovered Radium-226 in 1898, it opened up the atom’s secrets and offered hope that its mysterious radioactive rays were a miracle cure. Sobering reality replaced euphoria as radium factory workers began to die.
Radium taught the world of radiation’s dangers, yet it was not until 2005 that Congress put all aspects of radium safety oversight under the federal government. Until that time, it was primarily regulated — to varying degrees — by the states. This three-part blog series traces radium’s long unique history where states took the lead in regulating it and compensating victims.
Soon after the Curies’ discovery, radium became a consumer and medical sensation. Its radiation reduced tumor growth, and researchers found somewhat elevated levels of radiation at some medicinal spas, such as Saratoga Springs, N. Y., and Hot Springs, Ark. Conclusion? Radiation was a life saver. One physician claimed that radium’s “radiation prevents insanity, rouses noble emotions, retards old age, and creates a splendid youthful joyous life.”
Manufacturers hawked quack products they claimed were laced with radium as a miracle cure and status symbol: elixirs, kitchenware, clothes, pillows, razor blades, and cigarette holders, even condoms. Radium’s luminescent properties also made possible glow-in-the-dark paint for watch dials.
In 1925, the New York Times reported one of the earliest instances of radiation-induced cancer. Its victims were young women—watch-dial painters in New Jersey, Connecticut and Illinois. The intricate work required them to “lip point” their brushes by licking them. Infections and cancers of the jaw followed from the ingested radium. The isotope’s bone-seeking properties and long half-life made it particularly dangerous. (The time required for the radioactivity to decrease by one-half is referred to as the half-life. The half-life of Ra-226 is about 1,600 years.)
The tragic story of the “radium girls” transformed radiation’s image from panacea to poison. Public discussion turned to compensating victims and limiting radium exposures—duties that usually fell to state courts and agencies. In New Jersey, reformers won their fight for a law allowing compensation for “radium necrosis.”
State labor and health agencies were able to halt lip pointing, but their power over industry was sometimes limited. For example, the New Jersey Labor Department issued to U.S. Radium Corporation an order to tighten safety for its dial painters — “comply or close.” It closed and moved elsewhere.
Federal agencies mostly deferred to state authority over radium. They issued studies, organized conferences, and developed voluntary safe work practices. The Federal Trade Commission had some influence in shutting down falsely advertised products, such as the “fountain of youth” tonic Radithor, but safety assurance was a state prerogative.
With World War II, change came as nuclear reactors of the U.S. wartime atomic program flooded the world with new isotopes, reducing to near insignificance radium’s commercial and medical applications. The Curies’ Nobel-Prize discovery was about to become an afterthought.
Gerald R. Ford was president. Median household income was $11,800. Gas cost 57 cents a gallon. And NRC inspectors, as part of the Independent Measurements Program, routinely hit the road in a fully equipped van containing a mobile laboratory. Inspectors measured samples of radioactive effluents from nuclear power plants, checking on the accuracy of sampling routinely done by the plants’ own laboratories.
The image directly above on the left shows an NRC inspector placing a liquid radioactive waste sample in a cryogenic detector for analysis of its isotopic composition. In the image directly above on the right, an NRC inspector reviews analytical data. A similar van, but with portable equipment, was used to verify measurements during safeguards inspections of materials facilities. During a safeguards inspection, the equipment was removed from the van and carried inside the facility for use.

NRC officials Harold Denton (left) and Victor Stello brief President Jimmy Carter and Pennsylvania Governor Thornburgh on the Three Mile Island accident back on April 1, 1979. According to the Presidential diary for that day, available here, the President first attended Sunday services before flying from the White House to the Air National Guard Facility in Middletown, Pa., by Marine helicopter.
After a tour of TMI, then-President Carter gave some remarks to reporters and local residents, and returned to the White House by 3:54 p.m., in time to get to St. Patrick’s Episcopal Church to watch his daughter, Amy’s, violin recital.
