nestling or radiological dispersal device

Through a FOIA filing, Paleofuture has obtained an orientation, promotional film that the US Department of Energy issued in 1976 to present ostensibly to Congress members in order to justify their budget item for a little programme called Nuclear Emergency Search Team (NEST) but without revealing too much about their covert operations and techniques, which makes an ideal conversation piece for addressing the horrors and abject anxiety that the public is spared when it comes the daily duties of first responders.
Without peeking behind the arras periodically, one might think that the job of governing is a walk in the park. Run of the mill bomb-threats—in many cases hoaxes or attempts at extortion, suddenly in 1970s America became far more serious and fraught, with the menace of a dirty, nuclear-laced explosive being detonated in a crowded urban area. To this day NEST has maintained a low profile and the times it has been deployed to respond to a terrorist-threat involving nuclear materials have been under-reported and handled discreetly, sparing the public the burden of worry.
