Securing radiological sources on the go

Securing radiological sources on the go

February 4, 2020

RICHLAND, Wash. — Radioactive materials are a critical tool in a number of industrial applications, particularly oil and gas drilling and welding. While these sources are safe and well-regulated for their intended use; if lost or stolen the materials could be used by terrorists to make dirty bombs. The Department of Energy’s Pacific Northwest National Laboratory has developed and licensed a technology system to keep track of and secure radiological material on the road or at jobsites. Golden Security Services of Miami, Florida, will produce and deploy the Mobile Source Transit Security, or MSTS, system starting at several sites in Latin America.

“The system is a first line of defense against radiological terrorism and provides situational awareness if the material is tampered with or moved from where it is supposed to be,” said PNNL MSTS project manager Brian Higgins.

According to the Nuclear Regulatory Commission, most radiological dispersal devices would not release enough radiation to kill people or cause severe illness. But they certainly could create fear and panic, contaminate property and require potentially costly cleanup. The National Nuclear Security Administration sponsored PNNL to develop the MSTS system to help protect such material from theft, loss, or tampering.

PNNL used its extensive radiological and radio frequency expertise to develop the MSTS system, which consists of detection devices and radiofrequency tags specifically designed to track devices—including those commonly used in the oil and gas industries—that contain radiological material.

“Technology transfer to industry is an important mission of the Laboratory, especially in the area of nuclear security where the consequences can be severe,” said Kannan Krishnaswami, who manages commercialization of national security technologies for PNNL. “Partnering with industry allows for such security solutions to be commercially deployed, allowing PNNL to refocus its efforts on the next generation of scientific and technical challenges.”

Golden Security Services will produce the system and make it available to companies that manage the estimated thousands of radiological sources internationally. Golden Security Services has an exclusive license to commercialize the technology in Latin America — Mexico, Central America and South America — and non-exclusive rights to the technology in the United States and Canada.

MSTS sensor technology and associated software can determine when a radiological source moves from where it’s supposed to be and alerts officials. Components of the system work together to control and secure the sources from home base to the field and back. The MSTS can also detect changes in radiation levels, which can indicate a source has been taken from its shielding cask. Likewise, a master control unit monitors sensors and runs decision processing software to detect any tampering with or removal of the radiological material. Global Positioning Systems track the location of the transport vehicle to and from the job site. All data are available to system users through a custom MSTS software.

PNNL partnered with Baker Hughes, an international oil field services company, to understand the issues and balance operational needs with national security concerns.
