Abstract

C. J. Johnson et al. (Science 193:488 (1976)) separated the respirable fraction of surface dust by ultrasonic dispersion and water sedimentation. This probably resulted in respirable fractions that included particulates too large to fall within the respirable size range, and reasons for believing this is the case are given. It is pointed out that all of the Pu outside is virtually in the respirable size range. Sampling by vacuum and collection by impaction is suggested as a way of measuring the content of Pu actually associated with respirable dust particles. A reply by C. J. Johnson, R. R. Tidball, and R. C. Severson is included. (DLC)
