ABSTRACT
Item
Obtaining detailed photographs of the early stages of
the first hydrogen bomb explosion in 1952 posed a number
of problems. First, it was necessary to invent a
continuous-~access camera which could solve the problem
that existing million-picture-per-second cameras were
blind most of the time. The solution here was to alter
an existing camera design so that two modified cameras
could be mounted around a single high-speed rotating
mirror. A second problem, acquiring the necessary lenses
of precisely specified focal lengths, was solved by
obtaining a large number of production lenses from war
surplus salvage. A third hurdle to be overcome was to
test the new camera at an A-bomb explosion. Finally, it
was necessary to solve the almost impossible difficulty
of building a safe camera shelter close to a megaton
explosion. This paper describes the way these problems
were solved. Unfortunately the successful pictures that
were taken are sill classified.

The Office of the US Nuclear Waste Negotiator was
created as an independent federal agency by the US
Congress pursuant to the 1987 amendments to the Nuclear
Waste Policy Act of 1982. The office, which was
authorized by Congress for 5 years following the
enactment of the 1987 amendments, is headquartered in
Boise, Idaho, and maintains a liaison office in
Washington DC. The negotiator is charged with the
responsibility of attempting to find a state or Indian
