This TIB discusses the special exposure characteristics that may be encountered by energy employees who work with gloveboxes and provides special dose correction factors or modifiers that should be applied to affected energy employee's dose. It should be noted that throughout this technical information bulletin, the term glovebox is used, however, in the early years of the Atomic Energy Commission (AEC) facilities; these types of units were commonly called dry boxes as their original intent was to isolate radioactive materials. Throughout this report these terms should be considered equivalent.

Worker Outreach Activities

Based on a recommendation from the Advisory Board to provide workers and site experts with opportunities to participate in developing the technical documents used in dose reconstruction, NIOSH established a Worker Outreach Program.

At Worker Outreach Meetings, current and former DOE and AWE employees have opportunities to obtain information about Site Profiles, Technical Basis Documents, and Technical Information Bulletins, and to provide information for consideration and possible use in dose reconstruction. This process is valuable to ensure that the technical documents used in dose reconstruction contain correct and useful information.

Below are the Worker Outreach Activities for TIBs:

At the current time, no worker outreach activities specific to any TIB have been scheduled.

Worker Outreach meeting information for a specific work site and the minutes from the meetings can be found on the individual site pages. To view all information for a specific work site for which OCAS has developed information, please visit our List of Work Sites page. The information found on the individual work sites pages can include: technical documents (site profiles, technical basis documents, technical information bulletins), worker outreach information and final minutes, Special Exposure Cohort information, and public comments.

  • Revised August 12, 2005
    this document in PDF PDF 135 KB (25 pages)

    Document Number: ORAUT-OTIB-0004 Rev-03

    Revision Includes: Updates Appendix A, List of Applicable Facilities, and adds wording to clarify the application of the document. Allows for expansion to other facility types; includes estimate of industrial source exposures based on analyses of 1960-1980 commercial doses; deletes applicability (at this time) to U-recovery with phosphoric acid; adds type S assumption; used activity rather than mass air concentrations for calculations; uses different specific activity assumption for consistency with IMBA; uses OCAS-TIB-009 ingestion scenario; adds consideration of urinalysis; adds RU and EU assumptions; updates MCNP ingot doses; modifies ingot external dose assumptions; modifies external dose contamination calculation by accounting for isotopic fractions to consider effect of EU; removes external organ doses, but provides separate analyses (concern from Task 5 that reconstruction methods subject to their program should not be in site profile - the line is still blurry); added nonpenetrating dose assumptions; added photofluorography assumption prior to 1962. Corrected Table 3-8, first row to acute. Addressed OCAS comments: explicitly stated exception to default radiography doses could be made on a case-by-case basis, limited Appendix A industrial exposures to covered periods, and changed Appendix A industrial dose estimates back to linear (versus exponential) fit of data.

    Page Change Revision Includes: Approved page change revision. Revised to change thorium intakes based on assumption of equal "mass" as uranium; changed equilibrium conditions with progeny in the thorium chain based on new calculations and included statement of significance of Th-230 to be consistent with the current Hanford internal dosimetry TBD. Changes occurred on pages 33, 34, and 35. In Table 6-9 on page 35, in Section 6.7, corrected error in fission product intake in 1944-47 and adjusted I-131 intakes to be consistent with the Hanford Internal Dosimetry TBD. Made corrections to Table A-1 on page 38 in Attachment A. Incorporates internal and NIOSH formal review comments. The discussion and tables in Section 6.8 about radionuclides not measured in this study was removed. It is addressed in ORAUT-TKBS-0006-5. The pages affected by these changes are 23, 28, 30, and 32. This revision results in a reduction in assigned dose and no PER is required. No sections were deleted. Section 6.0: added Pu mixture statement consistent with Table in Section 5.1. Section 6.2: replaced sentence indicating all uranium exposure meant thorium exposure and referenced the Hanford internal dosimetry TBD for buildings and periods of thorium exposure. Clarified that thorium at PUREX would be Type M. In Table 6-4, corrected Type S intake for 1962-70 to 60.0 pCi/d; corrected PUREX type M intake to 0.957 based on type F. Added footnotes. Removed Table 6-5 on impurities in RU and referenced the TBD.
