Both Buddy Hann and myself are satisfied with the collection and analysis techniques. We have placed personnel -samplers at seven stationary locations within the upstairs laboratory to gain experience in using the techniques and are now ready to apply the method whenever a personnel monitoring program is set up. The results of the testing within the lab are appended. MW :rw Att. cc: C. P. LeBlanc W. A. Hann W.
