DOE-STD-1121-98
3.1.5 Internal Dose Evaluation
C
method for evaluating internal doses from routine and special bioassay data, and
where appropriate, from workplace monitoring data, including personal air samplers
C
methods for calculating internal doses
C
methods for evaluating dose equivalents from specific radionuclides, mixtures of
radionuclides, and materials of differing chemical characteristics
C
basis for the evaluation methods including recommendations given in ICRP
Publications and NCRP Reports, which embody improvements and updates of the
science of internal dosimetry
C
justification for alternative approaches and assumptions used in dose calculations
C
dose evaluation quality assurance
C
biokinetic models
C
model parameters
C
assumptions
C
individual-specific and facility-specific factors that are expected to change the dose
calculations by a factor of 1.5 or more
C
a description of the level of intake or committed effective dose equivalent detection
achieved
C
a basis for projecting a CEDE of one IL from bioassay results
3.1.6 Internal Dose Management
C
action levels for administrative response to intakes of radionuclides by workers,
including decisions reached among medical, management, and radiation protection
staff (RadCon Standard 523.6)
C
a description of the site policy for confirming intakes in instances of historical
bioassay data prior to January 1, 1989, where follow-up bioassay samples were not
required on positive bioassay samples or where documentation is lacking (counter
efficiency, chemical recovery, minimum detectable amount/activity, etc.)
C
methodology to account for the portion of a bioassay result that may be due to one
or more prior confirmed intakes
C
basis for work restrictions used during internal dose evaluation
C
administrative controls to limit dose to declared pregnant workers, minors, and
students
