These capabilities took on increased significance after the attacks of September 11, 2001, because of heightened concern that terrorists may try to detonate a nuclear or radiological device in a major U.S. city.
DOE is not the only federal agency responsible for addressing nuclear and radiological threats. The Department of Homeland Security (DHS) is responsible for preparing the country to prevent and respond to a potential nuclear or radiological attack. ...
....In the absence of clear mission responsibility, DOE and DHS have not informed cities about the surveys and have not conducted any additional surveys. DOE's two Remote Sensing Laboratories are protected at the lowest level of physical security allowed by DOE guidance because, according to DOE, capabilities and assets to prevent and respond to nuclear and radiological emergencies have been dispersed across the country and are not concentrated at the laboratories.
However, GAO analysts did find a number of critical capabilities and assets that exist only at the Remote Sensing Laboratories and whose loss would significantly hamper DOE's ability to quickly prevent and respond to a nuclear or radiological emergency.
These capabilities include the most highly trained teams for minimizing the consequences of a nuclear or radiological attack and the only helicopters and planes than can readily help locate nuclear or radiological devices or measure contamination levels after a radiological attack. Because these capabilities and assets have not been fully dispersed, current physical security measures may not be sufficient for protecting the facilities against a terrorist attack.
