It was shown that measurements of radioactive noble gases have been
used since the Manhattan Project in the 1940s and later during the
Cold War to monitor other countries on their nuclear (weapon)
programme and progress and has permanently been further
Nowadays, noble gases play an important role as a tool for
international nuclear verification regimes and are a key component
of the non-proliferation verification.

The history of the discovery, isolation, characterization,
production and use of argon, krypton, xenon, helium, and radon is
followed by an account of early attempts to react them with other
elements. The use of the electron shell theory of valence to
explain their inertness and the reactions of chemists to the
production of xenon compounds is described. The presently know n
compounds of xenon and krypton are listed, and the use of molecular
shapes of these compounds as determined by x-ray crystallagraphy
and electron diffraction to test theories of chemical bonding is
discussed. Illustrations, a short bibliography, and a film list are
