§82.14. What types of information could be used in dose reconstructions?
42 C.F.R. § 82.14
NIOSH will obtain the types of information described in this section for dose reconstructions, as necessary and available:
Subject and employment information,— including:
Gender;
Date of birth; and,
DOE and/or AWE employment history, including— job title held by year, and work location(s): including site names(s), building numbers(s), technical area(s), and duration of relevant employment or tasks.
Worker monitoring data,— including:
External dosimetry data, including external dosimeter readings (film badge, TLD, neutron dosimeters); and,
Pocket ionization chamber data.
Internal dosimetry data,— including:
Urinalysis results;
Fecal sample results;
In Vivo measurement results;
Incident investigation reports;
Breath radon and/or thoron results;
Nasal smear results;
External contamination measurements; and
Other measurement results applicable to internal dosimetry.
Monitoring program data,— including:
Analytical methods used for bioassay analyses;
Performance characteristics of dosimeters for different radiation types;
Historical detection limits for bioassay samples and dosimeter badges;
Bioassay sample and dosimeter collection/exchange frequencies;
Documentation of record keeping practices used to record data and/or administratively assign dose; and,
Other information to characterize the monitoring program procedures and evaluate monitoring results.
Workplace monitoring data,— including:
Surface contamination surveys;
General area air sampling results;
Breathing zone air sampling results;
Radon and/or thoron monitoring results;
Area radiation survey measurements (beta, gamma and neutron); and,
Fixed location dosimeter results (beta, gamma and neutron); and,
Other workplace monitoring results.
Workplace characterization data,— including:
Information on the external exposure environment, including— radiation type (gamma, x-ray, proton, neutron, beta, other charged particle); radiation energy spectrum; uniformity of exposure (whole body vs partial body exposure); irradiation geometry;
Information on work-required medical screening x rays; and,
Other information useful for characterizing workplace radiation exposures.
Information characterizing internal exposures,— including:
Radionuclide(s) and associated chemical forms;
Results of particle size distribution studies;
Respiratory protection practices; and
Other information useful for characterizing internal exposures.
Process descriptions for each work location,— including:
General description of the process;
Characterization of the source term (i.e., the radionuclide and its quantity);
Extent of encapsulation;
Methods of containment;
Other information to assess potential for irradiation by source or airborne dispersion radioactive material.
