Lorsque l'effet de réflexion sur le sol intervient, l'hypothèse d'une source image fictive implique qu'il n'y a pas d'absorption à la surface du sol et que la réflexion du panache est parfaite. De même cette formule ne tient pas compte des réactions chimiques possibles dans l'atmosphère. En outre, comme elle traduit une répartition Gaussienne [sic] des concentrations sur les axes transversaux, cette dernière ne devient significative que pour des temps d'intégration suffisants, compris entre 10 et 20 minutes selon la structure de la turbulence; mais il est évident que seule une valeur intégrée est biologiquement utilisable et que la connaissance de pointes extrêmes de concentrations ne présenterait pas en principe d'intérêt. Toutefois, avec l'accroissement des puissances d'émission on observe parfois, en atmosphère neutre surmontée d'une inversion, des arrivées de panache au sol même, à proche distance de la cheminée, pendant des durées non négligeables, et d'autant plus dangereuses que les puissances d'émission sont alors considérables. 1, record 5, French, - r%C3%A9partition%20gaussienne%20des%20concentrations

To estimate the vapour concentrations downwind of an accident site for determination of the flammability or toxicity hazard zone, the atmospheric dispersion of a contaminant vapour is modelled as a "puff" or "plume" according to the decision tree given in Figure 3. A gas leak form a tank is considered a semi-continuous point source, modelling as a plume, whereas the release of a large amount of gas over a very short time period of the order of seconds to minutes is considered an instantaneous point source modelled as a puff. 1, record 7, English, - flammability%20hazard%20zone
