Site Profile
Note: The Site Profile below can be used to complete dose reconstructions for Area IV of the Santa Susana Field Laboratory, the Canoga Avenue Facility (Vanowen Building), the Downey Facility, and the De Soto Avenue Facility (these are sometimes referred to as Energy Technology Engineering Center [ETEC] or Atomics International).
- Introduction
(Revised August 30, 2006)
 PDF 128 KB (8 pages)
Revision Includes: Revision to change site name to Atomics International throughout
document in keeping with revised DOE site naming conventions. Approved issue of Revision 01. Added information to Site Description in Section 1.2.1 on page 6. No further changes occurred as a result of formal internal review. Incorporates NIOSH formal review comments. This revision results in no change to the assigned dose.

(Approved February 2, 2006)
PDF 1.6 MB (47 pages)
- Occupational Medical Dose
(Revised October 31, 2008)
PDF 224 KB (25 pages)
Revision Includes: Revision to change the site name to Area IV of the Santa Susana
Field Laboratory, the Canoga Avenue Facility, the Downey Facility,
and the De Soto Avenue Facility (sometimes referred to as Energy
Technology Engineering Center [ETEC] or Atomics International) to
match the new DOE site naming conventions. Added Attributions
and Annotations section. Organ doses are revised as follows:
AP lumbar spine, before 1971, uterine dose is decreased by a
factor of 10; correcting an error,
AP and LAT lumbar spine, after 1997, except for breast and
remainder, all organ doses are marginally decreased due to a
change in beam quality assumption,
AP and LAT lumbar spine, all years, remainder organ dose is
increased by a factor ranging from 2 to 15 due to a change in
the reference organ used to define the remainder.
Doses to skin at additional locations to the primary beam entrance
are added in accordance with Revision 01 of ORAUT-PROC-0031.
All skin doses at newly tabulated locations are lower than the skin
dose at the primary beam entrance location. Maximum organ dose
tables for PA and LAT chest, and AP and LAT lumbar spine, are
deleted in accordance with Revision 01 of ORAUT-PROC-0031. A
discrepancy between the dose tables and the text is corrected. The
corrected frequency is lower to ensure any misunderstanding due to
the discrepancy that would result in a favorable to claimant dose
assessment. Text in Section 3.5.1.2 about examination frequency is
relocated to Section 3.4 where it logically belongs.
Breast doses from AP lumbar spine projections for periods after 1971
are increased by a factor 2.2 to 2.6. For the LAT lumbar spine
projections the breast dose increases range from no change, up to a
factor of 1.1. The increase results from a change in the assumed
dose conversion factors recommended by the Principal Medical
Dosimetrist.
The term "view" is globally replaced with the more modern term
"projection" and the term Entrance Skin Exposure (ESE) is replaced
by the more modern term "entrance air kerma." The term "routine"
when describing examination frequency is replaced by the more
descriptive word "periodic." The terms "entrance" and "exit" in
Tables 3-2 through 3-5 are replaced with "pre-employment" and "termination."
Additional information on eye/brain organ doses prior to 1971 is
added to Tables 3-2 and 3-3. The column showing entrance skin
exposure in Table 3-2 through 3-5 is eliminated as this is not needed
for dose reconstruction.
The possibility that photon energy could be less than 30 keV is
eliminated as this is applicable only to mammography.
Testes dose in Table 3-5 associated with LAT lumbar spine
exposures after 1997 decreases by 60% as a data error in the DCF
is corrected.
The description of skin doses has been modified to match that in
newly issued guidance, and skin dose tables have been separated
into two each for clarity in describing doses under poorly collimated
versus well collimated exposure conditions.
Incorporates formal NIOSH review comments. Constitutes a total
rewrite of the document.

Revision Includes: Incorporates SEC information in Section 4.1 and formal internal and NIOSH review comments.
- Occupational Internal Dose
(Revised April 26, 2010)
PDF 1.5 MB (82 pages)
Revision Includes: Revision to change the site name to Area IV of the Santa Susana Field Laboratory,
the Canoga Avenue Facility, the Downey Facility, and the De Soto Avenue Facility (sometimes referred to as Energy
Technology Engineering Center [ETEC] or Atomics International. Updated required language in Section 5.1. Additional
information added on the solubility of uranium aluminide and sensitivity of bioassay analyses. Added Attachment G,
Sensitivity of Bioassay Analyses by Bioassay Code U. S. Testing and Other Laboratories. Acronyms added for ICRP,
kCi, kg, mo, POC, TTF, wk, µCi, µm, and §. Changes are being made to Section 5.1.3, Scope, as requested by DOL to
clarify which organizations performed work eligible for compensation. Reporting levels and MDAs were adjusted in
Table 5-3 for NSEC. A paragraph was deleted from Section 5.2, Internal Dosimetry Overview. The abbreviation "UR"
for uranium radiometric was added to Section 5.3.1.3. Last paragraph of Section 5.3.1.4 was modified to clarify
the sensitivity (reporting level) vs. MDA. The numbers and order in the documents for tables 5-7 and 5-8 were
switched. An additional footnote was added to Table 5-9. Minor changes were made to the references and glossary.
A list of figures was added to Attachment B. The figures and descriptions in Attachment A were reordered, the
descriptions of two forms were combined, and in some cases descriptions were added to the same page as the figures.
Attachment D was split into two attachments (D and E) and the original attachments E and F were re-lettered to F
and G. The Table in Attachment G was split into in-vitro and in-vivo tables. Numerous minor edits were also made
to clarify or improve the readability of the document without changing the technical content. Added Attributions
and Annotations section. Activity fractions for reactors and related facilities were eliminated and references
to OTIB-0054 were added. Added SEC information and added information in Section 5.3.1.5 pertaining to the use of
CEP data. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of document.

Revision Includes: Incorporates SEC information in Section 6.1.2 and corrected an error in Table 6-8 pertaining to NTA film and
footnote b. 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.
At the current time, no PERs or PEPs specific to Downey Facility 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 Downey Facility:
At the current time, worker outreach activities have not been scheduled.
