ABSTRACT:
A personal dosimeter for measuring the average concentration of a gaseous contaminant over a given period of time is provided. The dosimeter comprises a sealed pouch having a reaction chamber, which contains a gas-collecting medium, and at least one compartment. Each compartment can be separately sealed and can contain a different reagent, the seals being individually breakable such that the reagents can be separately released into the reaction chamber. Into the pouch is sealed a gas diffusion device that permits the contaminant to diffuse into the reaction chamber where it is collected in proportion to its ambient concentration.
