Generally speaking the noble gases, Xe133 and Xe135 are considered
submersion hazards, with negligible internal hazards.  ICRP 68 lists
them as SR-0.  In spite of that it has been long known that there is a
small component that can be attached to the fatty tissues when
inhaled.  I see there were a few early attempts to compute internal
doses from Xenon in Technical papers, HP Vol 38 by Howard and Sommers
1979, and Journal of Nuclear Medicine,1977 by Susskind et al.  Has
anyone got (can you forward to me) more current dose coefficients for
the inhalation of these isotopes of Xenon or other more recent
technical papers?
