ABSTRACT:
A gaseous contaminate personal dosimeter which comprises a container; an inert porous thin barrier element forming one side of the container, the barrier element adapted to permit the diffusion of the gaseous contaminates that are to be determined into the interior of the container; and a gaseous contaminate-collecting medium within the container and positioned opposite the barrier element to collect gaseous contaminate diffused from the ambient atmosphere through the barrier element; and means to inhibit convection movement of the diffused gases within the container, whereby the dosimeter permits the determination of gaseous contaminate in proportion to ambient concentrations independent of ambient convection patterns.
