# §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.
