Preventing a Dirty Bomb


Engaging hospitals, industry and governments on radiological risks

Challenge

Ingredients for a radiological “dirty bomb” include the same isotopes that make lifesaving blood transfusions and cancer treatments possible. These materials are located at thousands of sites in more than 150 countries—often poorly secured and vulnerable to theft.

Action

Engage with hospitals, industry, and governments to raise awareness about this threat and the availability of safe and effective alternatives to the isotope of greatest concern, cesium-137.

Results

Officials and hospitals in Atlanta, New York City, and California are taking steps to replace equipment containing cesium-137.

The risk of a radiological “dirty bomb” attack continues to grow. Radical terrorist organizations are increasingly expressing interest in acquiring and using radioactive material in a radiological “dirty bomb.” In 2016, Belgian investigators discovered terrorists monitoring an employee at a highly enriched uranium (HEU) reactor that also produces medical isotopes.

Cesium-137 is an isotope found in blood irradiators and other medical equipment in many countries around the world. It is also the most dangerous of all radioactive isotopes. If cesium-137 was used in a dirty bomb, its highly dispersible powder would contaminate an area for years, costing billions of dollars in evacuation, demolition, and clean-up.

Fortunately, significant advancements in technology in recent years have yielded safe and effective non-radioactive x-ray devices for sterilizing blood that are approved by the U.S. Food and Drug Administration. Replacing the cesium-137 irradiators with these x-ray devices has security and fiscal benefits: It requires less security, completely eliminates the threat, doesn’t require expensive disposal at the end of the machine’s life cycle, and eliminates a hospital’s liability and protects those without insurance to cover terrorism losses.

NTI works with hospitals, governments, and the private sector to raise awareness about the threat of cesium-137 and other dangerous isotopes and to encourage the use of safe and effective alternatives that eliminate the threat permanently. In New York City, Mount Sinai Hospital committed to replacing all its cesium-137 blood and research irradiators with x-ray technology and the city’s Department of Health and Mental Hygiene launched a city-wide campaign to eliminate all dangerous radioactive sources as rapidly as possible. In Atlanta, NTI worked with Emory University Hospital, which received a Medical Innovation Award at the 2016 Nuclear Industry Summit for its efforts to reduce radiological threats by replacing a cesium-137 blood irradiator. NTI is also working with officials in California, which has many radioactive sources, to raise awareness and address the risk.
