An experimental study of radionuclide dispersion in the atmosphere has been conducted at BR1 research reactor Mol, Belgium. Artificially generated aerosols ('white smoke') were mixed with routine releases (41)Ar reactor's 60-m tall venting stack. The detailed plume geometry was measured remote sensing (Lidar) aerosol plumes while surface radiation levels under using gamma detectors downwind distances up to 1500 m from release point. A database built simultaneous measurements and field decay, together in-situ meteorological parameters. joint tracer/radiation dataset subsequently used evaluate accuracy predictions parameters fluence rates obtained by atmospheric dose rate model RIMPUFF.
