Revision Includes: Adds Purpose and Scope
sections. Constitutes a total rewrite of document. Adds Attributions
and Annotations section. Incorporates formal internal and NIOSH
review comments. This revision results in an increase in assigned
dose and a PER is required due to the addition of median photon
adjustment values in Tables 6-22 and A-8; otherwise, the maximum
values were replaced with lower 95th percentiles, and therefore
would lower doses. An exception to the lower 95th-percentile values
is the value for Other Operations, which is higher than the previously
reported maximum value of annual geometric means. This change
will result in a higher dose. Changes in Table A-7 will increase
skin/shallow dose for LAMPF/LANSCE workers.

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 compensability of a completed dose reconstruction may be effected, 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: Los Alamos National Laboratory TBD Revision
PDF 18 KB (2 pages)
Document Number: OCAS-PER-0018 Rev-00
About this Document: New document to determine which
previously completed claims require
evaluation for the effect of revising the
LANL TBD.
Approved: July 31, 2007
Summary: It is not possible to precisely determine the effect of the change to LAMPF dose estimates on Probability of Causation without a new Dose Estimate. However, it is possible to determine if the LAMPF energy distribution was used in the original dose estimate. It is also possible to determine if an individual was assigned unmonitored neutron dose based on neutron to photon ratios and whether the ratio used will increase or decrease under the new revision to the TBD.
In order to determine the effect of these factors, the individual cases must be re-examined. Since the unmonitored neutron dose has the potential of affecting every claim, all claims completed prior to May 30, 2007 from Los Alamos National Laboratory with a Probability of Causation less than 50% will require a review. NIOSH will request claims be returned in which the LAMPF energy distributions were originally assigned using Revision 0 for a new dose estimate. NIOSH will also request the return of claims in which the original dose estimate utilized a neutron to photon ratio that has now increased. For all other claims, NIOSH will review the claim against any other revisions to other technical documents that may affect the claim. DOL will be provided with a statement for each claim indicating what changes the claim was reviewed against and why the change did not affect the particular dose estimate or the Probability of Causation calculation. For any claims where it is not possible to provide this statement without a new Dose Estimate, NIOSH will request that DOL return the claim for a new Dose Estimate.
NIOSH has determined that 300 claims meet the criteria for further review. The remaining cases with a probability of causation less than 50% (1 claim) were completed using revision 1 of the TBD. NIOSH will provide DOL with the list of 300 claims as well as a determination on each claim as to whether a new Dose Estimate is required.

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 LANL:

Advisory Board Work Group on LANL Site Profile and SEC
This Work Group is responsible to review the Los Alamos site profile (as revised), to review the SEC petition(s) from Los Alamos petitioners, to review the NIOSH Evaluation Report of the petition, to review the SC&A Review of the Los Alamos Site Profile, to consider issues raised by the Board's contractor (SC&A) concerning the site profile and the petition Evaluation Report, and to assist 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 also strive to develop recommendations to the Board on adding one or more classes to the SEC.

Special Exposure Cohort Petition Information for LANL
- Classes Added to the SEC
Employees of the DOE predecessor agencies and their contractors or subcontractors who were monitored or
should have been monitored for exposure to ionizing radiation associated with radioactive
lanthanum (RaLa) operations at Technical Area 10 (Bayo Canyon Site), Technical Area 35 (Ten Site), and Buildings H, Sigma, and U (located within Technical Area 1) for a number of work days aggregating at least 250 work days during the period from September 1, 1944, through July 18, 1963, or in combination with work days within the parameters established for one or more classes of employees in the SEC.
Employees of the Department of Energy (DOE), its predecessor agencies, or DOE contractors or subcontractors who were monitored or should have been monitored for radiological exposures while working in operational Technical Areas with a history of radioactive material use at the Los Alamos National Laboratory (LANL) for a number of work days aggregating at least 250 work days from March 15, 1943 through December 31, 1975, or in combination with work days within the parameters established for one or more other classes of employees in the Special Exposure Cohort.
