Report of Personnel and Man-Rom by Work and Job Function This report is a tabulation on an annual basis of the number of station, utility, and other personnel (including contractors) who received exposures greater than 100 mrem / year and their associated man-rem exposure according to work and job function.

The work and job function totals for personnel greater than 100 mrem / year are different than the grand totals because an individual may perform work under more than one work l andjob function during the year.

l

! The total man-rem is based on a ratio of the official TLD results.
