(Revised November 7, 2006)
PDF 208 KB (12 pages)
Document Number: ORAUT-OTIB-0021 Rev-01
About this Document: Establishes the technical basis to provide information to allow Dose Reconstructors (Health Physicists) to assign doses to workers at the X-10 site who have no or limited monitoring data, based on site coworker data.
Revision Includes: Approved Revision 01 due to release of ORAUT-OTIB-0052, Rev.
00. Per new document requirements, added a table of contents.
This revision results in an increase in assigned dose and a PER is
required. This revision also documents minor corrections to Table 2
that do not require a PER.

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.
At the current time, no PERs or PEPs specific to Oak Ridge National Laboratory (ORNL/X-10) have been developed. However, we have developed PERs and PEPs that pertain to multiple sites. To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs) page.

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 Oak Ridge National Laboratory (ORNL/X-10):
- April 5, 2005

Advisory Board Work Group on Oak Ridge National Laboratory (ORNL/X-10)
This Work Group is responsible for reviewing the ORNL Site Profile, the SEC petition from ORNL petitioners, the NIOSH Evaluation Reports responding to the petition, and the SC&A Review of the ORNL Site Profile, considering issues raised by the Board's contractor (SC&A), and for assisting NIOSH and SC&A in the resolution of such issues. The Work Group may recommend to the Board, changes in the Site Profile as appropriate. The Work Group should strive to develop a recommendation to the Board on whether an additional class from ORNL should be added to the SEC.
