For the verification of the Comprehensive [nuclear] Test Ban Treaty
(CTBT) an organisation is buing built up in Vienna. The verification
system will comprise inter alia a global radionuclide measurement
system of 80 stations. Using atmospheric transport models, the
possible source locations of eventual sources of radioactivity
are to be determined. Models available for this task at the International
Data Centre (IDC) of the CTBTO are to be evaluated. In particular,
members of the expert group carry out their own simulations. IMP is
working with the model FLEXPART in backward mode for that purpose.
