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.

  • Evaluation of the Effect of Adding Ingestion Intakes to Bethlehem Steel Cases
    this document in PDF PDF 31 KB (3 pages)

    Document Number: OCAS-PER-0003 Rev-00

    About this Document: Describes the evaluation of the programmatic effect of the effect of adding ingestion intakes to Bethlehem Steel cases.

    Approved: January 28, 2005

    Summary: As a result of adding ingestion intakes, the probability of causation of none of the previously completed Bethlehem Steel claims would increase to greater than 50%.


  • Evaluation of the Effect of Revision 2 of the Site Profile on Previously Completed Bethlehem Steel Cases
    this document in PDF PDF 42 KB (7 pages)

    Document Number: OCAS-PER-0007 Rev-00

    About this Document: New document to evaluate the effect of revision 2 of the site profile on previously completed dose reconstructions from Bethlehem Steel.

    Approved: November 9, 2006

    Summary: The Bethlehem Steel Technical Basis Document was revised on July 27, 2006. The revision changed the estimated quantity of uranium inhaled and ingested as well as external dose to the skin. As a result of revisions to the Bethlehem Steel Technical Basis Document, three claims that were previously determined to have a PC of less than 50% will now have a PC greater than 50%. Eight cases that previously had a PC greater than 50% now have a PC less than 50%. This report, along with detailed information on the specific cases and calculations, has been provided to DOL for determination of further action.

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 the Bethlehem Steel:

Advisory Board Work Group on the Use of Surrogate Data

This Work Group will consider the conditions under which "surrogate" data can be used as a valid substitute for actual data for a given site. The Work Group will seek to establish the type and importance of various parameters (e.g., type of nuclide, amounts of material, chemical and physical forms, processes, working conditions, and other such parameters) that impact on worker dose, and will consider the extent to which such parameters at one site may apply to other sites. The Work Group may also consider the extent to which theoretical considerations can be properly used to bound dosed in the absence of actual workplace measurements. The Work Group should strive to develop a policy recommendation that can be adopted by the Board regarding the use of surrogate data. This Work Group was asked to consider the application of surrogate data criteria to the Texas City Chemicals, Inc., site in relation to the SEC petition for that facility.

      Please note that as part of the procedures and processes of the Advisory Board's Work Groups, several kinds of pre-decisional documents may be developed. These documents, which can include white papers, matrices, working drafts, etc., are distributed among the Work Group members as research and background tools to facilitate discussion and deliberation. The discussions during the above meeting may cover a pre-decisional document. Because these types of documents are pre-decisional in nature, may contain sensitive information, and may change over time, they are not posted on our Web site. These finalized, reviewed and redacted pre-decisional documents are also available to other interested parties through an appropriate Freedom of Information Act request. Requests for documents not in the public domain should be submitted to the CDC/ATSDR Freedom of Information Act Office at foiarequests@cdc.gov.

Previous Versions of Bethlehem Steel Corporation Documents

  • Basis for Development of an Exposure Matrix for Bethlehem Steel Corporation

    • Revised July 27, 2006
      this document in PDF PDF 395 KB (41 pages)

      Revision Includes: Approved issue of Revision 0 of OCAS-TKBS-003. This supersedes rev. 1 of the previous ORAUT-TBKS-0001.

      An Exposure Matrix indicates the type and quantity of radiation exposure to individuals for a specific location and specific time. Locations can be as broad as an entire facility or as narrow as a single small room. Time can be years, months, or even a single event. When personnel monitoring data are incomplete or do not exist, an exposure matrix is developed to estimate the dose. The matrix is typically developed using a combination of personnel monitoring data in conjunction with area monitoring data. Once the exposure is estimated, data about how long the worker was exposed (time) is used to estimate their total exposure.

      There was no identified documentation that contained personal monitoring data for employees of the Bethlehem Steel site. Therefore, an exposure matrix that relied on air sampling data was developed to estimate radiation dose to many individuals. The matrix that was developed can be used to estimate the dose for a large number of the employees at the Bethlehem Steel site.

      In many cases, the development of a facility specific matrix is more difficult but due to the limited operations that took place in this AWE, this matrix was able to be developed more quickly. The following documented facts were used in the development of this matrix:

      1. Uranium processing occurred on one rolling mill.

      2. The amount of time involving work with uranium was no more than 500 hours total over a four year period.

      Because of these two facts, the workplace exposure conditions could be estimated from the available data. Once the workplace exposures were estimated, Bethlehem Steel employees are then assumed to be exposed to these "worst-case scenario" conditions as a claimant favorable approach.
