This report presents the findings of an investigation of a number of techniques for cleaning ambient air with special emphasis on their applicability to the removal of the short-lived radioactive decay products of 222-radon, the so-called "radon daughters" that have been identified with the induction of lung cancer in underground uranium miners. The purpose of the study was to review the requirements for control of radon daughter concentrations in mine air, and to examine all techniques whose feasibility has been demonstrated in principle and that would be capable of meeting those requirements. The study included a review of all pertinent literature, both technical and proprietary, on the subject of the control of miner exposure to the radon daughters and in the area of potentially applicable air-cleaning technology. Information about the nature of the problem and about the experience of the uranium mining industry in applying air-cleaning methods to its solution was obtained by visiting mines where such methods are in use and by correspondence and telephone conversations with other industry sources.
