DOE-STD-1128-98
-- upgrade bioassay measurement systems and workplace monitoring practices to
provide state-of-the-art measurements
-- ensure that internal dose assessments use state-of-the-art technology.
-- ensure workplace monitoring programs are designed to identify potential intakes.
All confirmed occupational intakes of plutonium, regardless of magnitude, should be
assessed. The results of all bioassay and other measurements needed to support the
quality of measurements and dose assessment should be recorded and maintained.
The recording and reporting requirements for internal dosimetry data are set forth in
Section 3.7 of this report; however, the following is a summary list of internal
dosimetry information for which recording is required:
-- Total CEDE from all intakes during a year
-- committed dose equivalent (CDE) to organs or tissues of concern from all intakes
during a year
-- magnitude of intake for each radionuclide during a year
-- data necessary to allow subsequent verification, correction, or recalculation of
doses
-- gestation period dose equivalent to the embryo/fetus from intake by the declared
pregnant worker during the entire gestation period.
Radiation exposure records programs must also provide for the summation of internal
and external doses, as required by 10 CFR 835.702 (DOE, 1998a). While the
summation process is not necessarily performed under a site internal dosimetry
program, it behooves the program to recognize what is required. The following
summations are identified by 10 CFR 835.702(c) (5) and (6):
-- Total effective dose equivalent (TEDE) defined as the summation of effective
dose equivalent (deep dose equivalent) from external exposure and the CEDE
-- summation of the effective dose equivalent (deep dose equivalent) from external
exposure and the CDE to organs or tissues of concern
-- cumulative TEDE
-- for the embryo/fetus of a declared pregnant worker, the summation of the deep
dose equivalent to the mother from external exposure during the entire gestation
period and the gestation period dose equivalent to the embryo/fetus from intakes
by the mother during the entire gestation period.
