Section 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:(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: (2) Fecal sample results;(3) In Vivo measurement results;(4) Incident investigation reports;(5) Breath radon and/or thoron 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.
