II. VCM Dosimetry Program
Two major changes were made In the program:
A. Vinyl department shift workers are now being scheduled by job classifica tion Instead of by name as in the past. The scheme also results in a more random schedule with respect to time of day and day of week.
B. Dosimetry equipment handling methods were simplified by reducing the num
ber of people who handle each sample. All REAL badge carbon handling is now being done by lab personnel.
