DEVICE FOR SAMPLING AND CONTROLLING RADIOACTIVE AEROSOLS

Abstract

Abstract Translated from French LA PRESENTE INVENTION CONCERNE UN DISPOSITIF DE PRELEVEMENT ET DE CONTROLE D'AEROSOLS RADIOACTIFS DANS UNE ATMOSPHERE. CE DISPOSITIF DE PRELEVEMENT ET DE CONTROLE, QUI EST DU GENRE DE CEUX QUI COMPRENNENT UNE CHAMBRE COMPORTANT A SA PARTIE INFERIEURE UNE OUVERTURE OBTUREE PAR UN FILTRE PLAQUE DE MANIERE ETANCHE CONTRE LA PAROI DE LADITE CHAMBRE PAR UN PRESSEUR DEGAGEABLE, AFIN DE PERMETTRE LA MISE EN PLACE D'UN NOUVEAU FILTRE, L'AIR A CONTROLER ETANT ASPIRE DANS LA CHAMBRE PAR UNE POMPE AU TRAVERS DUDIT FILTRE, SE CARACTERISE EN CE QUE LEDIT PRESSEUR EST SOLIDAIRE D'UNE MEMBRANE SOUPLE FORMANT UNE PAROI D'UNE CAPACITE ETANCHE, LA DEFORMATION DE LADITE MEMBRANE SOUS L'EFFET D'UNE DEPRESSION APPARAISSANT DANS LADITE CAPACITE ENTRAINANT LE DEGAGEMENT DU PRESSEUR, CE QUI PERMET LE REMPLACEMENT DU FILTRE. APPLICATION A LA SURVEILLANCE RADIOACTIVE D'UNE ATMOSPHERE. THE PRESENT INVENTION CONCERNS A DEVICE FOR SAMPLING AND MONITORING RADIOACTIVE AEROSOLS IN AN ATMOSPHERE. THIS SAMPLING AND CONTROL DEVICE, WHICH IS OF THE KIND OF THOSE WHICH INCLUDE A CHAMBER INCLUDING AT ITS LOWER PART AN OPENING CLOSED BY A PLATE FILTER IN A WATERTIGHT MANNER AGAINST THE WALL OF THE SAID CHAMBER BY A RELEASABLE PRESSOR, TO ENABLE IT IN PLACE OF A NEW FILTER, THE AIR TO BE CONTROLLED BEING SUCKED INTO THE CHAMBER BY A PUMP THROUGH THE SAID FILTER, IS CHARACTERIZED IN THAT THIS PRESSER IS SOLIDARITY OF A FLEXIBLE MEMBRANE FORMING A WALL WITH A TIGHT CAPACITY, THE DEFORMATION OF THE SAID MEMBRANE UNDER THE EFFECT OF A DEPRESSION APPEARING IN THE SAID CAPACITY CAUSING THE RELEASE OF THE PRESSER, WHICH ALLOWS THE REPLACEMENT OF THE FILTER. APPLICATION TO RADIOACTIVE SURVEILLANCE OF AN ATMOSPHERE.
