Kantian Nonideal Theory and Nuclear Proliferation [PDF]

open access: yes, 2010
Recent revelations of Iran’s hitherto undisclosed uranium enrichment programs have once again incited western fears that Tehran seeks nuclear weapons’ capability. Their fears seem motivated by more than the concern for compliance

An Airborne and Vehicular Gamma Survey of Greenham Common, Newbury District and Surrounding Areas [PDF]

open access: yes, 1997
The airborne gamma ray survey recorded more than 40,000 scintillation spectra and 20,000 spectra from semiconductor detectors. The vehicular survey produced a further 1346 and 763 spectral sets respectively. The installation, calibration, recording and

Towards Monte Carlo based Full Spectrum Modeling of Airborne Gamma-Ray Spectrometry Systems [PDF]

open access: yesarXiv
This monograph presents advancements in Airborne Gamma-Ray Spectrometry (AGRS), a critical tool for emergency response to radiological incidents such as severe nuclear accidents or nuclear weapon detonations. Current AGRS calibration and data evaluation methods struggle to accurately quantify many radioactive materials expected in radiological ...

Mind the Gap: Foundation Models and the Covert Proliferation of Military Intelligence, Surveillance, and Targeting [PDF]

open access: yesarXiv
Discussions regarding the dual use of foundation models and the risks they pose have overwhelmingly focused on a narrow set of use cases and national security directives-in particular, how AI may enable the efficient construction of a class of systems referred to as CBRN: chemical, biological, radiological and nuclear weapons. The overwhelming focus on

Methodologies for Evaluating Security Risk and Safeguards for HEU to LEU conversion of a Miniature Neutron Source Reactor (MNSR) using SCALE and ORIGEN [PDF]

open access: yes, 2018
Rising global opinions on security of vulnerable nuclear materials at research reactor facilities against misuse and acquisition by terrorist or violent groups has led to the implementation of the enrichment reduction program focused at reducing ...

Development and validation of a high-fidelity full-spectrum Monte Carlo model for the Swiss airborne gamma-ray spectrometry system [PDF]

open access: yesarXiv
Airborne Gamma-Ray Spectrometry (AGRS) is a critical tool for radiological emergency response, enabling the rapid identification and quantification of hazardous terrestrial radionuclides over large areas. However, existing calibration methods are limited to a few gamma-ray sources, excluding most radionuclides released in severe nuclear accidents and ...

When Terrorism Threatens Health: How Far are Limitations on Personal and Ecomonic Liberties Justified [PDF]

open access: yes, 2003
The government is engaged in a homeland-security project to safeguard the population\u27s health from potential terrorist attacks. This project is politically charged because it affords the state enhanced powers to restrict personal and economic ...
