ABSTRACT OF THE DISCLOSUREDevice for analyzing the activity of a radio-active aerosol as a function of the grain size distribut-ion of its particles of the type comprising a tightenclosure, means for circulating the aerosol through saidenclosure and within the latter, a plurality of stagesfor collecting aerosol particles with a given grain size,each of the stages comprising an aerosol injection plateperforated by at least one calibrated opening and a col-lection plate for particles of a given grain size, whereinit comprises means for establishing an electric fieldbetween the injection and collection plates of each of thestages with a view to establishing an ionisation currentthrough a stage during the disintegration of the particlescollected in the latter and means for measuring the ion-isation current of one of the said stages.
