Abstract

L’invention concerne un procédé de surveillance de la contamination radioactive atmosphérique d’un milieu (1) mis en œuvre à partir d’un système de surveillance (10) de la contamination radioactive atmosphérique, le système de surveillance (10) comprenant un moniteur de mesure (100) de la contamination radioactive atmosphérique, ci-après CAM, et un dispositif de comptage et de classification en taille de particules (200). Le procédé comprend notamment des étapes de mesure, à partir du dispositif de comptage et de classification en taille de particules (200), d’au moins une grandeur caractéristique des particules présentes dans le milieu (1)et de la détermination, à partir de l’au moins une grandeur caractéristique, d’au moins un facteur de correction k d’une activité relative aux rayonnements alpha artificiel vis-à-vis d’une activité relative aux rayonnements alpha naturel. L’invention concerne en outre un système de surveillance (10) permettant la mise en œuvre d’un tel procédé. Figure pour l’abrégé : figure 1The invention relates to a method for monitoring the atmospheric radioactive contamination of a medium (1) implemented from a monitoring system (10) of the atmospheric radioactive contamination, the monitoring system (10) comprising a monitor measuring device (100) for atmospheric radioactive contamination, hereinafter CAM, and a particle size counting and classification device (200). The method comprises in particular steps of measuring, from the particle size counting and classification device (200), at least one characteristic quantity of the particles present in the medium (1) and of determining, from the at least one characteristic quantity, of at least one correction factor k of an activity relating to artificial alpha radiation with respect to an activity relating to natural alpha radiation. The invention further relates to a monitoring system (10) for carrying out such a method. Figure for abstract: figure 1
