on pages 10-13 in Section 1.0 (extension of class to 12/31/1958) as instructed by NIOSH. Updated NIOSH
required language on pages 10 and 11 in Section 1.0. Added information on pages 106-108 in Section 6.5.
Updated NIOSH reference on pages 106-108, 124, 128 and 216 in Sections 7.1, 7.3, 8.5, 8.6, and
Attachment A, respectively. Added reference on page 141 in Reference Section. On pages 158-160, updated
NIOSH and ORAUT references in Reference Section. On page 210, updated NIOSH reference in Table A-34.
Table A-40 on page 215 was revised to clarify that tabulated intakes represent gross alpha activity and
to provide guidance on isotopic mixture to be applied. Incorporates formal internal and NIOSH review
comments.

Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs)
NIOSH is committed to applying the best available science in dose reconstructions. In keeping with this commitment, completed cases with probabilities of causation less than 50% are reviewed as relevant new information becomes available. The results of these reviews are described in a Program Evaluation Report (PER). The PER details the effect, if any, of the new information on the completed dose reconstruction. If it appears that the new information may result in an increase in dose for a completed dose reconstruction with a probability of causation of less than 50%, NIOSH is committed to working with the Department of Labor to reopen and rework the dose reconstruction, as appropriate. A Program Evaluation Plan (PEP) describes plans for evaluating specific program details or issues.
Program Evaluation Report: Mallinckrodt TBD Revision
 PDF 16 KB (2 pages)
Document Number: OCAS-PER-0015 Rev-00
About this Document: New document to determine which
previously completed claims require
evaluation for the effect of revising the
Mallinckrodt TBD.
Approved: July 31, 2007
Summary: It is not possible to determine the magnitude of the change to dose without a new dose estimate. Since (as of issuance of this PER) no Mallinckrodt claims have yet been completed with the newest revision to the TBD, NIOSH is requesting that all Mallinckrodt claims with a dose reconstruction performed using Revision 1 of ORAUT-TKBS-0005 that have a Probability of Causation less than 50% be returned for a new estimate. A list of the population of 16 potentially affected claims is attached. A new dose reconstruction will be completed for each of the claims using the latest revision to the Mallinckrodt TBD.

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 Mallinckrodt Chemical Co., Destrehan Street Plant:
At the current time, worker outreach activities have not been scheduled.

Previous Versions of Mallinckrodt Chemical Company Documents
- Technical Basis Document: Basis for Development of an Exposure Matrix for
the Mallinckrodt Chemical Company St. Louis Downtown Site and the St. Louis Airport Site, St.
Louis, Missouri
- Revised June 14, 2007
PDF 1.7 MB (222 pages)
Revision Includes: Reflects comments of the ABRWH.
Constitutes a total rewrite of the document. Modified Purpose and
Scope, and Appendix A to incorporate SEC information as instructed
by NIOSH. Made minor editorial changes to eliminate readily
discernable errors and eliminated extraneous intake tables. Added
information to reconstruct doses from available monitoring and
coworker data for the period 1949-1962, and to clarify some
discrepancies between the early-in-the program draft and current
guidance. Deleted Appendix D (which was formerly C). This revision
changes the method for assigning uranium, radium and thorium
coworker intakes and radon exposures and eliminates the application
of equilibrium amounts of uranium progeny intakes to reconstruct
dose. Incorporates formal internal and NIOSH review comments.
Revised dates for operational period in sections 6 and 7 to end in
1958. Removed references to unmonitored thorium and radium
exposures (since reconstruction of such exposures has been
determined to be not feasible by the SEC action). Added a section
titled "unmonitored raffinate exposures" to cover the period 1948 -
1958 and inserted the text "reserved" to indicate that reconstruction of
internal exposure from such pathways is not covered in this TBD for
the time period 1948 - 1958. This revision results in an increase in
assigned dose and a PER is required.
- Revised March 10, 2005
PDF 1.0 MB (248 pages)
Revision Includes: Incorporated comments on Section 8.0 and to incorporate additional lately captured information. Revision to incorporate comments on Sections 7.0 and 8.0; to incorporate additional lately captured information regarding site work and external and radon exposure rates; to incorporate neutron exposure information; to incorporate information about the St. Louis Airport Site (SLAPS); and to provide additional guidance to dose reconstructors. Section 7.0, regarding
external dose, remains on hold. Incorporated NIOSH comments.
