§ 82.14 What types of information could be used in dose reconstructions?

NIOSH will obtain the types of information described in this section for dose reconstructions, as necessary and available: (a) Subject and employment information, including: (1) Gender; (2) Date of birth; and, (3) 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. (b) Worker monitoring data, including: (1) External dosimetry data, including external dosimeter readings (film badge, TLD, neutron dosimeters); and, (2) Pocket ionization chamber data. (c) Internal dosimetry data, including: (1) Urinalysis results; (2) Fecal sample results; (3) In Vivo measurement results; (4) Incident investigation reports; (5) Breath radon and/or thoron results; (6) Nasal smear results; (7) External contamination measurements; and (8) Other measurement results applicable to internal dosimetry. (d) Monitoring program data, including: (1) Analytical methods used for bioassay analyses; (2) Performance characteristics of dosimeters for different radiation types; (3) Historical detection limits for bioassay samples and dosimeter badges; (4) Bioassay sample and dosimeter collection/exchange frequencies; (5) Documentation of record keeping practices used to record data and/or administratively assign dose; and, (6) Other information to characterize the monitoring program procedures and evaluate monitoring results. (e) Workplace monitoring data, including: (1) Surface contamination surveys; (2) General area air sampling results; (3) Breathing zone air sampling results; (4) Radon and/or thoron monitoring results; (5) Area radiation survey measurements (beta, gamma and neutron); and, (6) Fixed location dosimeter results (beta, gamma and neutron); and, (7) Other workplace monitoring results. (f) Workplace characterization data, including: (1) 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; (2) Information on work-required medical screening x rays; and, (3) Other information useful for characterizing workplace radiation exposures. (g) Information characterizing internal exposures, including: (1) Radionuclide(s) and associated chemical forms; (2) Results of particle size distribution studies; (3) Respiratory protection practices; and (4) Other information useful for characterizing internal exposures. (h) Process descriptions for each work location, including: (1) General description of the process; (2) Characterization of the source term (i.e., the radionuclide and its quantity); (3) Extent of encapsulation; (4) Methods of containment; (5) Other information to assess potential for irradiation by source or airborne dispersion radioactive material.
