Over the past decade the Department of Energy/NNSA has recovered thousands of sealed radioactive isotope sources from around the world that were abandoned, unwanted or no longer needed.
Sealed nuclear sources are utilized for a variety of industrial, medical or military purposes. But at the end of their useful life they can still pose a safety or security hazard.
So the mission of the DOE/NNSA Off-Site Source Recovery Program is to take possession of “orphan” sources in the interest of public safety and security.
The Program says it has taken control of nearly 40,000 disused and unwanted nuclear sources — about 1.25 million Curies of radioactive material — from 1,400 sites in the US and 25 other countries.
The achievements of the Program were summarized last week in Strengthening Cradle-to-Grave Control of Radioactive Sources by Bill Stewart, Los Alamos National Laboratory, December 11, 2017.
The systematic recovery and control of nuclear materials became an explicit priority during the Obama Administration.
“We are leading a global effort to secure all vulnerable nuclear materials from terrorists,” the Administration’s 2010 National Security Strategy stated. “We are dramatically accelerating and intensifying efforts to secure all vulnerable nuclear materials. . . . We will seek to complete a focused international effort to secure all vulnerable nuclear material around the world through enhanced protection and accounting practices, expanded cooperation with and through international institutions, and new partnerships to lock down these sensitive materials.”
The 2015 Obama National Security Strategy likewise affirmed that “Keeping nuclear materials from terrorists . . . remains a high priority.”
The 2017 National Security Strategy that was published by the White House this week also addressed control of nuclear materials, though in a comparatively terse and generic manner:
“Building on decades of initiatives, we will augment measures to secure, eliminate, and prevent the spread of WMD and related materials, their delivery systems, technologies, and knowledge to reduce the chance that they might fall into the hands of hostile actors. We will hold state and non-state actors accountable for the use of WMD.”
The new National Security Strategy included one reference to national security classification, citing it as a potential obstacle to information sharing:
“The U.S. Government will work with our critical infrastructure partners to assess their informational needs and to reduce the barriers to information sharing, such as speed and classification levels.”
In anticipation of future known and unknown health security threats, including new pandemics, biothreats, and climate-related health emergencies, our answers need to be much faster, cheaper, and less disruptive to other operations.
To unlock the full potential of artificial intelligence within the Department of Health and Human Services, an AI Corps should be established, embedding specialized AI experts within each of the department’s 10 agencies.
Investing in interventions behind the walls is not just a matter of improving conditions for incarcerated individuals—it is a public safety and economic imperative. By reducing recidivism through education and family contact, we can improve reentry outcomes and save billions in taxpayer dollars.
The U.S. government should establish a public-private National Exposome Project (NEP) to generate benchmark human exposure levels for the ~80,000 chemicals to which Americans are regularly exposed.
