美国国家核安全局称，钴-60放射源若被恐怖分子或其他对手窃取，将构成安全威胁

美国官员出于担忧该材料可能被窃取用于制造“脏弹”，将一种用于癌症治疗的高放射性材料从危地马拉运回美国本土。
这批钴-60放射源此前被安置在一台废弃的医疗放射设备中，美危两国团队将该放射性部件拆除后，运往美国的安全存储地点。
美国国家核安全局（NNSA）周四宣布了此次行动，称这是防止危险放射性材料落入恐怖分子及其他对手手中的 broader 行动的一部分。
此次行动于5月启动，来自新墨西哥州洛斯阿拉莫斯国家实验室的美国国家核安全局专家与危地马拉的一处设施合作，拆除了一台产自美国的含钴-60远程放射治疗设备中的相关部件。
危地马拉官员为行动提供了运输、后勤和实物安全支持。

钴-60被用于医疗设备治疗癌症，但美国国家核安全局表示，高放射性放射源若被窃取将构成安全威胁。该机构称，从危地马拉拆除的这批材料可能被用于制造放射性武器，也就是俗称的“脏弹”。
此次拆除行动正值特朗普政府强调防止恐怖分子获取化学、生物、放射性或核武器之际。该政府2026年反恐战略将阻止恐怖分子获得此类武器列为美国国家安全的关键责任。
“我们的使命很简单：保护美国公民、守护我们的边境，确保对手永远无法获取可能伤害我国的材料，”美国国家核安全局国防核不扩散办公室副主任马修·纳波利说道。

“此次成功拆除是国土安全的重大胜利，也彰显了我们与危地马拉政府的良好合作关系。美国国家核安全局将尽一切努力保卫美国，保障我们社区的安全，”纳波利补充道。
据美国国家核安全局介绍，危地马拉国家放射性废物中心以及能源和矿产部为此次行动提供了运输、后勤和实物安全支持。
“多亏我们与美国国家核安全局和国防威胁降低局合作，从我们的设施中移除了高风险放射性材料，我们得以消除其对我国社区和国家构成的危险，”危地马拉能源和矿产部技术实验室负责人迈拉·比利亚托罗说道。

“钴-60放射源的成功遣返是美国政府跨部门合作的成果，”国防威胁降低局核运输与处置项目主管罗伯特·布里奇斯说道。“我们很自豪能与美国国家核安全局合作，为消除放射性风险、保障美国安全采取切实行动。”

US removes radioactive cancer-treatment material from Central American country over ‘dirty bomb’ risk

NNSA says the cobalt-60 source posed a security threat if stolen by terrorists or other adversaries
By Brittany Miller Fox News
A highly radioactive material used to treat cancer is back on U.S. soil after American officials removed it from Guatemala over concerns it could be stolen and used to create a “dirty bomb.”
The cobalt-60 source had been housed inside a disused medical radiation device before U.S. and Guatemalan teams removed the radioactive component and transported it to secure storage in the United States.
The U.S. National Nuclear Security Administration (NNSA) announced the operation Thursday, saying it was part of a broader effort to prevent dangerous radioactive materials from falling into the hands of terrorists and other adversaries.
The operation began in May, when specialists from the NNSA’s Los Alamos National Laboratory in New Mexico worked with a facility in Guatemala to remove part of a U.S.-origin teletherapy machine containing cobalt-60.
Guatemalan officials assisted with transportation, logistics and physical security.

Cobalt-60 is used in medical devices to treat cancer, but the NNSA said highly radioactive sources can pose a security threat if stolen. The agency said the material removed from Guatemala could have been used to create a radiological weapon, commonly known as a “dirty bomb.”
The removal comes as the Trump administration emphasizes preventing terrorists from obtaining chemical, biological, radiological or nuclear weapons. The administration’s 2026 Counterterrorism Strategy identifies preventing terrorists from acquiring such weapons as a critical U.S. national security responsibility.
“Our mission is simple: protect American citizens, secure our borders, and ensure our adversaries never get their hands on materials that could harm our country,” Matthew Napoli, deputy administrator for the NNSA’s Office of Defense Nuclear Nonproliferation, said.

“This successful removal is a massive win for homeland security and demonstrates our positive relationship with the Guatemalan government. NNSA will do whatever it takes to defend America and keep our communities safe,” Napoli added.
Guatemala’s National Centre of Radioactive Wastes and Ministry of Energy and Mines provided transportation, logistical and physical security support during the operation, according to the NNSA.
“Thanks to our collaboration with NNSA and DTRA in removing high-risk radioactive material from our facility, we were able to eliminate the danger it posed to our community and country,” Mayra Villatoro, head of the Unit of Technical Laboratories at Guatemala’s Ministry of Energy and Mines, said.
After the NNSA securely packaged the cobalt-60 component, the Defense Threat Reduction Agency (DTRA) provided secure transportation back to the U.S.

“The successful repatriation of the cobalt-60 source is a product of vital U.S. Government interagency cooperation,” Robert Bridges, DTRA program manager of Nuclear Transportation & Disposition, said. “We are proud to work with NNSA to take meaningful action in their mission to eliminate radiological risk and keep America safe.”

The operation is part of the NNSA Office of Radiological Security’s work with foreign governments and other partners to remove high-activity radioactive material and strengthen protections around radioactive sources.
