Abstract

L'invention concerne un procédé de cartographie en temps réel d'un paramètre représentatif d'une radioactivité dans un environnement, le procédé comprenant les étapes suivantes : - mesurer (S1) au moins une valeur dudit paramètre via au moins un instrument de mesure mobile passant par un ensemble d'au moins un point de mesure de l'environnement, chaque valeur mesurée étant associée à des données spatiales, - estimer (S3) une valeur dudit paramètre en chaque point d'un ensemble d'au moins un point d'estimation de l'environnement par une interpolation spatiale de la ou des valeurs mesurées en fonction des données spatiales respectivement associées à ladite ou auxdites valeurs mesurées du paramètre et de coordonnées spatiales du point d'estimation considéré, - générer (S4) une carte représentative de la radioactivité dans l'environnement en fonction de la ou des valeurs mesurées, des données spatiales respectivement associées à ladite ou auxdites valeurs mesurées, de la ou des valeurs estimées et des coordonnées spatiales dudit ou desdits points d'estimation, et - mettre à jour (S7) la carte générée par réitération des étapes de mesure et d'estimation.The invention relates to a method for real-time mapping of a parameter representative of radioactivity in an environment, the method comprising the following steps: - measuring (S1) at least one value of said parameter via at least one mobile measuring instrument passing through a set of at least one environmental measurement point, each measured value being associated with spatial data, - estimating (S3) a value of said parameter at each point of a set of at least one point d estimation of the environment by a spatial interpolation of the measured value (s) as a function of the spatial data respectively associated with the said measured value (s) of the parameter and of the spatial coordinates of the estimation point considered, - generate (S4) a representative map of radioactivity in the environment as a function of the measured value (s), of the spatial data respectively associated with the said value (s) measurements, of the estimated value or values and of the spatial coordinates of said one or more estimation points, and - updating (S7) the map generated by reiterating the measurement and estimation steps.
