An encouraging development in the search for an instrument that will provide a real-time measurement of the airborne respirable dust exposure of a coal miner is the Volkwein Respirable Dust Dosimeter (RDD). The performance of the Respirable Dust Dosimeter (RDD) was evaluated against that of the Personal Gravimetric Sampler (GRD) under identical conditions in both underground mines and the laboratory. In all, 114 RDDs (48 in underground mines and 66 in laboratory) were used side-by-side with GRDs in carefully designed experiments to generate comparative data. Data from experiments indicate that the respirable dust dosimeter can be used to assess the cumulative respirable dust exposure of an underground coal miner on a real-time basis. In this paper, the details of the design, results, and conclusions of the underground and the laboratory experiments are presented.
