The ability to detect a clandestine nuclear explosion in order to verify a ban on nuclear testing and to detect violations has improved dramatically in the past two decades.
There have been “technological and scientific revolutions in the fields of seismology, acoustics, and radionuclide sciences as they relate to nuclear explosion monitoring,” according to a new report published by Los Alamos National Laboratory that describes those developments.
“This document… reviews the accessible literature for four research areas: source physics (understanding signal generation), signal propagation (accounting for changes through physical media), sensors (recording the signals), and signal analysis (processing the signal).”
A “signal” here is a detectable, intelligible change in the seismic, acoustic, radiological or other environment that is attributable to a nuclear explosion.
The new Los Alamos report “is intended to help sustain the international conversation regarding the [Comprehensive Test Ban Treaty] and nuclear explosive testing moratoria while simultaneously acknowledging and celebrating research to date.”
“The primary audience for this document is the next generation of research scientists that will further improve nuclear explosion monitoring, and others interested in understanding the technical literature related to the nuclear explosion monitoring mission.”

“A ban on all nuclear tests is the oldest item on the nuclear arms control agenda,” the Congressional Research Service noted last year. “Three treaties that entered into force between 1963 and 1990 limit, but do not ban, such tests. In 1996, the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which would ban all nuclear explosions. In 1997, President Clinton sent the CTBT to the Senate, which rejected it in October 1999.”
Despite the uphill battle the country is facing, Dr. Schlaerth feels optimistic about the future possibilities of industrial decarbonization.
A supply-side tax credit (STC) could offer a tax incentive to material suppliers and professional service consultants that provide goods or services to affordable housing projects.
The Department of Housing and Urban Development (HUD), Department of Commerce, and Department of Transportation should jointly develop and manage a data resource—a Housing Production Dashboard—to track housing production within and across states.
Exempting affordable housing from volume caps would address the underlying issue and have the greatest impact in this housing emergency.
