Interoffice Communication To A. H. Sather From J. V. Uptain Date October 19, 1979 Subject VCM DOSIMETRY - AUGUST SEPTEMBER, 1979 REc E/VED 0CT 251979 Following are the results of VCM dosimetry during August and September, 1979. 112 samples were taken, 16 of which indicated overexposure. Range,, PPM August No. Samples % September No. Samples ~Y~ 0.0 - 0.5 0.5 - 1.0 1.0 - 5.0 5.0+ 33 70.21 44 67.69 6 12.77 13 20.00 8 17.02 6 9.23 i 0 0 2 3.0* ? 47 100.0 65 100.Of The results of the 16 overexposures are shown in Table I. Under the system used until this/week, the specific causes for VCM exposures identified by dosimetry have not always been identifiable. In most cases, it appears that overexposed individuals have had difficulty recalling probable causes several days after the fact. Starting this week, we are trying * new system, which requires the recording of probable causes by the person being monitored, and during each sample taken. It is anticipated that this method will give more useful information that can be used to pinpoint and eliminate causes of overexposures. Attachments c: JJJirODS 0#
