- Introduction
(Revised October 1, 2007)
 PDF 170 KB (10 pages)
Revision Includes: Initiated to include References and Attributions
and Annotations sections. Minor editorial changes made. No further
changes occurred as a result of formal internal review. Incorporates
formal NIOSH review comments.
- Site Description
(Approved May 7, 2004)
PDF 565 KB (65 pages)
- Occupational Medical Dose
(Revised September 14, 2010)
PDF 219 KB (18 pages)
Revision Includes: Incorporates data captured since the last revision to better
document what has come to be known about PFG at LANL, and to add skin doses for all projections
and periods. Added references and included Attributions and Annotations Section. Incorporates
formal internal and NIOSH review comments. Constitutes a total rewrite of the document.
- Occupational Environmental Dose
(Revised March 26, 2010)
PDF 1.6 MB (96 pages)
Revision Includes: Adds new environmental external and uptake data
prior to 1971. Added Attributions and Annotations section. Incorporated SEC-00061
and SEC-00051. Intakes to assign maximum doses for four primary radionuclides during
the specified employment period for the class of Los Alamos National Laboratory
employees added to the Special Exposure Cohort (1943-1975) are included. Section
4.1.3.3 clarified 'partial' dose reconstruction with respect to ambient external
dose; additional instructions to dose reconstructors were added to section 4.3.1,
'Ambient Radiation.' These state that on-site ambient dose is to be based on the
environmental film badge and TLD results available from 1965 onward. In support
of this, rows with years prior to 1965 were deleted from Table 4-26. Single
correction to a preposition in Section 4.2.1. Incorporates review comments from
formal internal and NIOSH review. Incorporates changes required by the adoption
of an 83.14 SEC determination. This alters the definition of the class of Los
Alamos National Laboratory employees added to the SEC (1943-1975), and removes
the area-specific and monitoring restrictions from the class definition making
the SEC class now include all employees in all areas of the LANL during the
period 1943-1975. Constitutes a total rewrite of the document.
- Occupational Internal Dose
(Revised October 15, 2009)
PDF 1 MB (150 pages)
Revision Includes: Incorporates information from documents not available at the time
the original document was published. The current information
available for uranium has been incorporated into Section 5.2.4.
Clarification of MDAs, UNAA/DNAA analysis results, guidance for
selection of enrichment, and a description of the new LANL Bioassay
Repository database content have been included. Appropriate
references have been added. For claims involving uranium UNAA
bioassay results: Because of the ambiguity in the interpretation of
the uranium bioassay results when results were transferred into the
Bioassay Repository, the guidance in the TBD might not have been
interpreted consistently by DRs and PRs. UNAA/DNAA data
provided by LANL is for DU and EU rather than U-238 and U-235. A
table providing an aged "pure" 238Pu mixture has been provided for
use when exposures to heat source technology plutonium is
suspected. Changes to the mixture might affect the total dose for
plutonium intakes evaluated as "pure" 238Pu. In addition, the Tiger
Team Assessment (DOE 1991), the Human Experiments and the
details of the RaLa SEC Report (NIOSH 2006) have been included in
the revision. Incorporates formal internal and NIOSH review
comments. Adds Attributions and Annotations section. A description
of the class of employees added to the SEC for SEC Petition-00051
was added to the text describing the class of employees added under
SEC Petition-00061 (employees associated with RaLa operations).
A new Section 5.2.4.6 was added describing the limitations on
internal dose reconstruction for employees in the non-excepted TAs
(as listed in the petition). Added statement about only partial dose
reconstructions are possible for most TAs. A new bullet was added
in Section 5.7.2, General Guidance, indicating that only partial
internal dose reconstructions are possible. Incorporates methods for
estimating maximum doses in accordance with the evaluation report
for Petition SEC-00109, changes to address comments by OCAS
commenters, updated dose reconstruction methodologies and
references, and addition of an algorithm to guide dose reconstructors
for dose calculation and dose assignment. Constitutes a total rewrite
of the document.
- Occupational External Dose
(Revised November 23, 2009)
PDF 1 MB KB (77 pages)
Revision Includes: Updated NIOSH references in
Sections 6-1, 6-2, A-6 and Reference Section. Added details to the
Scope in Section 6.1. In Section 6.2, "Reporting Practices"
was modified to distinguish between LANL records with non-penetrating
dose listed as "SHALLOW" vs. those listed as "SKIN."
Several changes were made to remove dose reconstruction methods and
information relating to periods when it has been determined to be
infeasible to estimate external doses. Specifically, according to the
HHS letter adding a class of LANL employees to the SEC (1943-1975),
partial dose reconstructions may include external doses from gamma
emitters in the years 1946-1975, neutrons from 1946-1975, and beta-emitters
in the years 1949-1975. Incorporates formal internal and NIOSH review
comments. No sections were deleted.

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: 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.

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.
