In essesnce, what the GAO found was;
"The Nuclear Regulatory Commission's (NRC) current system for verifying licenses does not adequately protect against the purchase of high-risk radioactive materials using a fraudulent license. Licenses control the type and quantity of radioactive material allowed to be possessed. Quantities of radioactive materials are defined as category 1 through 5, with 1 being the most dangerous. Using shell companies with fraudulent licenses, GAO successfully purchased a category 3 quantity of radioactive material of concern from two different vendors in the U.S. Specifically, GAO provided a copy of a license that GAO forged to two vendors, subsequently obtained invoices, and paid the vendors. GAO refused to accept shipment at the point of delivery, ensuring that the material was safely and securely returned to the sender.
As GAO has previously reported, a category 3 quantity of radioactive material can, on its own, result in billions of dollars of socioeconomic costs if dispersed using a dirty bomb. By purchasing more than one shipment of a category 3 quantity of radioactive material, GAO also demonstrated that a bad actor might be able to obtain a category 2 quantity by purchasing and aggregating more than one category 3 quantity from multiple vendors. NRC officials told GAO that NRC plans to proceed with existing initiatives to implement new verification regulations by late 2023 but does not plan to take immediate corrective actions to address the issues that GAO found."
