VCM PERSONNEL DOSIMETRY REVIEW
( ^ T" 13'f-1 ^
of -e XT i ST1f) q
Attached is a summary of VCM dosimetry results since March, 1977.
4
I recommend two changes in sampling frequency:
1, Transportation Warehouse Workers should go from a quarterly basis to a yearly basis (one sample per crew per year).
2. Process Engineers should go from a monthly basis to a quarterly basis (one sample per quarter).
No other changes in the sampling plan appear to be justified at this point.
