Evaluation Report Summary: SEC-00167, Downey Facility

This evaluation report by the National Institute for Occupational Safety and Health (NIOSH) 

addresses a class of employees proposed for addition to the Special Exposure Cohort (SEC) per the 

Energy Employees Occupational Illness Compensation Program Act of 2000, as amended, 42 U.S.C. 

§ 7384 et seq. (EEOICPA) and 42 C.F.R. pt. 83, Procedures for Designating Classes of Employees 

as Members of the Special Exposure Cohort Under the Energy Employees Occupational Illness 

Compensation Program Act of 2000.

NIOSH-Proposed Class Definition

All employees of the Department of Energy, its predecessor agencies, and their contractors and 

subcontractors who worked at the Downey Facility in Los Angeles County, California, from January 

1, 1948 through December 31, 1955, for a number of work days aggregating at least 250 work days, 

occurring either solely under this employment or in combination with work days within the 

parameters established for one or more other classes of employees included in the Special Exposure 

Cohort.

Feasibility of Dose Reconstruction Findings

NIOSH lacks sufficient information, which includes biological monitoring data, sufficient air 

monitoring information, or sufficient process and radiological source information, to allow it to 

estimate with sufficient accuracy the potential internal exposures to various radionuclides to which the 

proposed class may have been subjected. NIOSH finds that it is likely feasible to reconstruct external 

dose, including occupational medical dose, for the Downey Facility workers with sufficient accuracy.

The NIOSH dose reconstruction feasibility findings are based on the following:

• Principal sources of both internal and external radiation doses for members of the NIOSHproposed class included exposures to fission product and transuranic radionuclides associated with 

reactor, accelerator, and laboratory operations. Such sources of exposure were also present at 

Area IV of the Santa Susana Field Laboratory (SSFL) and the Canoga Avenue Facility when 

Downey Facility operations were transferred to the two sites in 1955. Downey, SSFL-Area IV, 

and Canoga were related facilities operated by North American Aviation.

• NIOSH previously determined in its evaluations of petitions SEC-00093 and SEC-00156 that 

some SSFL-Area IV workers could have received intakes of radioactive materials that went 

unmonitored from the beginning of the covered period for SSFL-Area IV operations in 1955 

through the end of 1964. NIOSH similarly determined in its evaluation of petition SEC-00151 

that the Canoga Avenue Facility also lacked an adequate routine bioassay monitoring program 

during its entire period of operations from 1955 through 1960. For both sites, limitations in the 

available data did not allow NIOSH to estimate radiation doses with sufficient accuracy. NIOSH 

therefore recommended SEC classes for SSFL-Area IV workers to include the time period from 

January 1, 1955 through December 31, 1964, and for Canoga Avenue Facility workers for the 

period from January 1, 1955 through December 31, 1960.
SEC-00167 03-24-10 Rev. 0 Downey Facility

4 of 77

• NIOSH has determined that the Downey Facility was the predecessor site for the nuclear 

operations and health physics practices of North American Aviation that were subsequently moved 

to Canoga and SSFL in 1955. This move resulted in a continuation of the Downey health physics 

practices. NIOSH has observed this continuation in the radiological records reviewed during its 

evaluations of petitions SEC-00093, SEC-00151, and SEC-00156 for the SSFL-Area IV and 

Canoga Avenue facilities.

• NIOSH has determined that limitations in the available Downey Facility data are consistent with 

the data limitations found for the SSFL-Area IV and Canoga Avenue facilities, and such 

limitations preclude NIOSH from estimating Downey Facility radiation doses with sufficient 

accuracy.

• Pursuant to 42 C.F.R. § 83.13(c)(1), NIOSH determined that there is insufficient information to 

either: (1) estimate the maximum radiation dose, for every type of cancer for which radiation 

doses are reconstructed, that could have been incurred under plausible circumstances by any

member of the class; or (2) estimate the radiation doses of members of the class more precisely 

than a maximum dose estimate.

• Although NIOSH found that it is not possible to completely reconstruct radiation doses for the 

proposed class, NIOSH intends to use any internal and external monitoring data that may become 

available for an individual claim (and that can be interpreted using existing NIOSH dose 

reconstruction processes or procedures). Therefore, dose reconstructions for individuals employed 

at the Downey Facility during the period from January 1, 1948 through December 31, 1955, but 

who do not qualify for inclusion in the SEC, may be performed using these data as appropriate.

Health Endangerment Determination

The NIOSH evaluation did not identify any evidence supplied by the petitioners or from other 

resources that would establish that the class was exposed to radiation during a discrete incident likely 

to have involved exceptionally high-level exposures, such as nuclear criticality incidents or other 

events involving similarly high levels of exposures. However, the evidence reviewed in this 

evaluation indicates that some workers in the class may have accumulated chronic radiation exposures 

through intakes of fission products and other radionuclides and from direct exposure to radioactive 

materials. Therefore, 42 C.F.R. § 83.13(c)(3)(ii) requires NIOSH to specify that health may have 

been endangered for those workers covered by this evaluation who were employed for a number of 

work days aggregating at least 250 work days within the parameters established for this class or in 

combination with work days within the parameters established for one or more other classes of 

employees in the SEC.

SEC Petition Evaluation Report for SEC-00167

ATTRIBUTION AND ANNOTATION: This is a single-author document. All conclusions drawn from 

the data presented in this evaluation were made by the ORAU Team Lead Technical Evaluator: 

Michael Domal, MJW Technical Services. The rationales for all conclusions in this document are 

explained in the associated text.

1.0 Purpose and Scope

This report evaluates the feasibility of reconstructing doses for employees who worked at a specific 

facility during a specified time. It provides information and analysis germane to considering a petition 

for adding a class of employees to the Congressionally-created SEC.

This report does not make any determinations concerning the feasibility of dose reconstruction that 

necessarily apply to any individual energy employee who might require a dose reconstruction from 

NIOSH, with the exception of the employee whose dose reconstruction could not be completed, and 

whose claim consequently led to this petition evaluation. The finding in this report is not the final 

determination as to whether or not the proposed class will be added to the SEC. This report will be 

considered by the Advisory Board on Radiation and Worker Health (the Board) and by the Secretary 

of Health and Human Services (HHS). The Secretary of HHS will make final decisions concerning 

whether or not to add one or more classes to the SEC in response to the petition addressed by this 

report.

This evaluation, in which NIOSH provides its findings both on the feasibility of estimating radiation 

doses of members of this class with sufficient accuracy and on health endangerment, was conducted in 

accordance with the requirements of EEOICPA and 42 C.F.R. § 83.14.

2.0 Introduction

Both EEOICPA and 42 C.F.R. pt. 83 require NIOSH to evaluate qualified petitions requesting that the 

Department of Health and Human Services add a class of employees to the SEC. The evaluation is 

intended to provide a fair, science-based determination of whether it is feasible to estimate, with 

sufficient accuracy, the radiation doses of the proposed class of employees through NIOSH dose 

reconstructions.

1

NIOSH is required to document its evaluation in a report, and to do so, relies upon both its own dose 

reconstruction expertise as well as technical support from its contractor, Oak Ridge Associated 

Universities (ORAU). Once completed, NIOSH provides the report to both the petitioners and the 

Advisory Board on Radiation and Worker Health. The Board will consider the NIOSH evaluation 

report, together with the petition, comments of the petitioner(s) and such other information as the 

Board considers appropriate, to make recommendations to the Secretary of HHS on whether or not to 

add one or more classes of employees to the SEC. Once NIOSH has received and considered the 

advice of the Board, the Director of NIOSH will propose a decision on behalf of HHS. The Secretary

of HHS will make the final decision, taking into account the NIOSH evaluation, the advice of the 

Board, and the proposed decision issued by NIOSH. As part of this final decision process, the 

petitioner(s) may seek a review of certain types of final decisions issued by the Secretary of HHS.

3.0 NIOSH-Proposed Class Definition and Petition Basis

The NIOSH-proposed class includes all employees of the Department of Energy, its predecessor 

agencies, and their contractors and subcontractors who worked at the Downey Facility in Los Angeles, 

California, from January 1, 1948 through December 31, 1955, for a number of work days aggregating 

at least 250 work days, occurring either solely under this employment or in combination with work 

days within the parameters established for one or more other classes of employees included in the 

Special Exposure Cohort. During this period, employees at this facility were involved with the 

operation of various types of nuclear reactors and particle accelerators.

The evaluation responds to Petition SEC-00167 which was submitted by an EEOICPA claimant 

whose dose reconstruction could not be completed by NIOSH due to a lack of sufficient dosimetryrelated information. NIOSH’s determination that it is unable to complete a dose reconstruction for an

EEOICPA claimant is a qualified basis for submitting an SEC petition pursuant to 42 C.F.R. § 

83.9(b).

NIOSH has determined that the Downey Facility, operated by North American Aviation (NAA), was 

the origin of many of the radiological control and monitoring practices, as well as radiological 

monitoring records programs, subsequently employed at multiple sites related to the Energy 

Technology Engineering Center (ETEC) operations at Area IV of the Santa Susana Field Laboratory 

(SSFL). The related sites included the Downey Facility, the De Soto Avenue Facility, the Canoga 

Avenue Facility, and Area IV of the SSFL (ORAUT-TKBS-0038-2). In 1955, NAA transferred its 

Downey Facility operations to its SSFL-Area IV and Canoga Avenue facilities. NIOSH has found 

dose reconstruction infeasibilities associated with these two successor facilities beginning in 1955.

There is currently one class of SSFL-Area IV workers associated with the NIOSH evaluation of SEC 

petition SEC-00093, for which the Secretary of Health and Human Services (HHS) has designated 

inclusion in the Special Exposure Cohort:

Class added to the SEC effective July 18, 2009: Employees of the Department of Energy (DOE), 

its predecessor agencies, and DOE contractors and subcontractors who worked in any area of 

Area IV of the Santa Susana Field Laboratory for a number of work days aggregating at least 250 

work days from January 1, 1955 through December 31, 1958, or in combination with work days 

within the parameters established for one or more other classes of employees in the SEC (HHS, 

2009). 

Detailed information associated with the SEC-00093 worker class added to the SEC can be found in 

the NIOSH evaluation report, SEC Petition Evaluation Report, Petition SEC-00093 (NIOSH, 2009). 

The basis for this 1955-1958 SEC class was the determination that NIOSH does not have access to 

sufficient personnel monitoring, workplace monitoring, or source term data to bound potential internal 

 2 See 42 C.F.R. pt. 83 for a full description of the procedures summarized here. Additional internal procedures are 

available at http://www.cdc.gov/niosh/ocas.

exposures from the various radionuclides for the evaluated worker class at Area IV of SSFL during 

the period from January 1, 1955 through December 31, 1958 (HHS, 2009).

Through the course of ongoing dose reconstruction, continued data capture efforts, and investigations 

associated with SEC-00093, NIOSH subsequently determined that there were insufficient access 

controls employed at SSFL-Area IV; as a result, there were some workers who should have been

monitored who were not, and who could have received unmonitored intakes of radioactive materials 

after 1958. During this subsequent investigation, NIOSH determined that the available bioassay data 

have limitations through the end of 1964 that preclude the development of adequate co-worker dose 

distribution models for the years prior to 1965. These NIOSH findings were presented in a second 

NIOSH evaluation report for Area IV of the SSFL, SEC Petition Evaluation Report, Petition 

SEC-00156 (NIOSH, 2010b), that resulted in NIOSH proposing a second SEC class to include DOE 

employees who worked at Area IV of the SSFL from January 1, 1959 through December 31, 1964.

NIOSH similarly determined in its evaluation of petition SEC-00151 that the Canoga Avenue Facility 

also lacked an adequate routine bioassay monitoring program during its entire period of operations 

from 1955 through 1960. These NIOSH findings were presented in a NIOSH evaluation report for the 

Canoga Avenue Facility, SEC Petition Evaluation Report, Petition SEC-00151 (NIOSH, 2010a), that 

resulted in NIOSH proposing an SEC class to include DOE employees who worked at the Canoga 

Avenue Facility from January 1, 1955 through December 31, 1960.

The Downey Facility originated many of the radiological practices and record-keeping programs 

subsequently employed at the SSFL-Area IV and Canoga Avenue facilities when operations ceased at 

the Downey Facility in 1955. The collective health physics records, including the ones for the 

Downey Facility are now stored at SSFL. NIOSH has determined that (as with SSFL-Area IV and the 

Canoga Avenue Facility) it also does not have access to sufficient personnel monitoring, workplace 

monitoring, or source term data to bound potential unmonitored internal exposures that may have 

occurred at the Downey Facility during its covered DOE operational period (1948 through 1955).

4.0 Radiological Operations Relevant to the Proposed Class 

The following subsections summarize the radiological operations at the Downey Facility from January 

1, 1948 through December 31, 1955, and the information available to NIOSH to characterize 

particular processes and radioactive source materials. Using available sources, NIOSH has attempted 

to gather process and source descriptions, information regarding the identity and quantities of 

radionuclides of concern, and information describing processes through which the radiation exposures 

of concern may have occurred and the physical environment in which they may have occurred. The 

information included within this evaluation report is meant only to be a summary of the available 

information.

4.1 Operations Description

The operating company for the Downey Facility in the 1940s was North American Aviation (NAA). 

The main operation during that era was airplane manufacturing. A small section of the facility was 

used for atomic research. Operations were conducted at the Atomic Energy Research Department 

(AERD), which later became the Atomics International Division when operations were moved to the 

Canoga Avenue Facility in 1955. AERD was involved in the research and development of atomic 

energy for the production of electric power, which was sponsored by the AEC (Downey, 2009).

The Downey Facility operations that were relevant to the NIOSH-proposed SEC class for all workers 

from 1948 through 1955 included nuclear research and development, bench-top nuclear 

experimentation and engineering studies. These activities involved the use of a 2-MeV Van de 

Graaff accelerator, a radiochemistry laboratory, and a neutron counting room. Activities also involved 

operations associated with the use of two small reactors, a 0.5-W teaching reactor and a 4-W water 

reactor known as a water boiler neutron source (WBNS) (ORAUT-TKBS-0038-2). The WBNS was 

used as a neutron source for an exponential pile. The exponential pile was a system designed to 

model different fuel/moderator lattice configurations. The neutron flux in theses lattices could be 

measured. The WBNS was in operation from 1952 through 1955. The majority of radioactive 

material present at Downey while the WBNS was in operation was due to canned normal and depleted 

uranium metal used in the exponential pile (ORAUT-TKBS-0038-2).

The radioactive materials used for the exponential piles and the WBNS were supplied by the AEC and 

government contractors. After use, the radioactive materials were either returned to the source or 

transferred to SSFL (ORAUT-TKBS-0038-2).

The research activities involved the handling, preparing, transferring, analyzing and storing of 

radioactive material. 

4.2 Radiation Exposure Potential from Operations

The Downey Facility had a 2-MeV Van de Graaff accelerator, a radiochemistry laboratory, a neutron 

counting room, and two small reactors. Radioactive materials were handled, prepared, transferred, 

and analyzed in these areas (ORAUT-TKBS-0038-2). These activities resulted in potential internal 

and external radiation exposures for Downey Facility workers during the DOE operations period from 

1948 through 1955. Because NIOSH has found indications that not all potentially-exposed workers 

were included in the personnel radiation monitoring program, an individual worker’s potential for 

radiation exposure at the Downey Facility cannot be determined based solely on the existence or nonexistence of individual monitoring records. 

4.3 Time Period Associated with Radiological Operations

Per the DOE Office of Health, Safety and Security, the time period associated with DOE operations at 

the Downey Facility is 1948-1955 (DOE, 2010). NIOSH has discovered no additional data to support 

more specific dates for the start and stop of DOE operations at the Downey Facility. Therefore, DOE 

work at the Downey Facility is assumed to have started on January 1, 1948 and continued through 

December 31, 1955.
SEC-00167 03-24-10 Rev. 0 Downey Facility

11 of 77

4.4 Site Locations Associated with Radiological Operations

Through the course of ongoing dose reconstruction and continued research for the Downey Facility 

and the other ETEC-related sites, NIOSH has determined that the site-specific and claimant-specific 

data available for the Downey Facility for the time period of this evaluation (1948-1955) are 

insufficient to allow NIOSH to characterize worker movements throughout the site. NIOSH is 

therefore unable to define individual worker exposure scenarios based on specific work locations at 

the Downey Facility. 

4.5 Job Descriptions Affected by Radiological Operations

Through the course of ongoing dose reconstruction and continued research for the Downey Facility 

and the other ETEC-related sites, NIOSH has determined that the site-specific and claimant-specific 

data available for the Downey Facility for the time period of this evaluation (1948-1955) are 

insufficient to allow NIOSH to determine that any specific work group was not potentially exposed to 

radioactive material releases or possible subsequent contamination. NIOSH has insufficient 

information associating job titles and/or job assignments with specific radiological operations or 

conditions and is, therefore, unable to define potential radiation exposure conditions based on worker 

job descriptions.

5.0 Summary of Available Monitoring Data for the Proposed Class

The primary data used for determining internal exposures are derived from personal monitoring data, 

such as urinalyses, fecal samples, and whole-body counting results. If these are unavailable, the air 

monitoring data from breathing zone and general area monitoring are used to estimate the potential 

internal exposure. If personal monitoring and breathing zone area monitoring are unavailable, internal 

exposures can sometimes be estimated using more general area monitoring, process information, and 

information characterizing and quantifying the source term.

This same hierarchy is used for determining the external exposures to the cancer site. Personal 

monitoring data from film badges or thermoluminescent dosimeters (TLDs) are the primary data used 

to determine such external exposures. If there are no personal monitoring data, exposure rate surveys, 

process knowledge, and source term modeling can sometimes be used to reconstruct the potential 

exposure.

A more detailed discussion of the information required for dose reconstruction can be found in 

OCAS-IG-001, External Dose Reconstruction Implementation Guideline, and OCAS-IG-002, Internal 

Dose Reconstruction Implementation Guideline. These documents are available at:

5.1 Data Capture Efforts and Sources Reviewed 

In addition to examining its Site Research Database (SRDB) to locate documents supporting the 

evaluation of the proposed class, NIOSH completed an extensive database and Internet search for 

information regarding the Downey Facility. The database search included the DOE Legacy 

Management Considered Sites database, the DOE Office of Scientific and Technical Information 

(OSTI) database, the Energy Citations database, the Atomic Energy Technical Report database, and 

the Hanford Declassified Document Retrieval System. In addition to general Internet searches, the 

NIOSH Internet search included OSTI OpenNet Advanced searches, OSTI Information Bridge fielded 

searches, Nuclear Regulatory Commission (NRC) Agency-wide Documents Access and Management 

(ADAMS) web searches, the DOE Office of Human Radiation Experiments website, and DOENational Nuclear Security Administration-Nevada Site Office searches. 

NIOSH’s data capture efforts include visits to the SSFL site in September and November 2009, and 

one visit to the San Bruno Federal Records Center in September 2009. NIOSH has worked with 

representatives from DOE Legacy Management and the SSFL site in an attempt to gather documents 

and data relevant to dose reconstruction of claims for the Downey Facility and the other ETEC-related 

sites. NIOSH’s SRDB currently contains over 1500 documents associated with the ETEC-related 

sites, including over 100 documents associated specifically with the Downey Facility. Attachment 1 

contains a summary of Downey-related documents. The summary identifies data capture details for 

each document retrieved.

5.2 Worker Interviews

To obtain additional information for related Santa Susana sites (i.e., Area IV of the Santa Susana Field 

Laboratory, Canoga Avenue Facility, De Soto Avenue Facility, and Downey Facility) NIOSH 

interviewed ten former Santa Susana employees. All ten interviews were reviewed for this Downey 

Facility evaluation and the following three interviews were deemed relevant to the Downey effort.

• Personal Communication, 2005, Personal Communication with ETEC Medical Staff Member;

Telephone Interview by ORAU Team; December 1, 2005; 12:00 PM EST; SRDB Ref ID: 20534

• Personal Communication, 2007a, Personal Communication with Health Physicist; Telephone 

Interview by ORAU Team; November 20, 2007 11:00 AM PST; SRDB Ref ID: 37534 

• Personal Communication, 2007b, Personal Communication with Health and Safety Manager; 

Telephone Interview by ORAU Team; November 30, 2007 9:00AM PST; SRDB Ref ID: 37538 

5.3 Internal Personnel Monitoring Data

Radionuclides of concern for the facilities and processes at Downey Facility were primarily fission 

products. Exposure to fissionable material, transuranics, and activation products was also possible 

(NIOSH, 2009). 

Through the course of ongoing dose reconstruction, continued data capture efforts, and investigations 

associated with SEC-00093, NIOSH has identified only limited amounts of internal personnel 

monitoring data for pre-1959 exposures at the ETEC-related sites; this is consistent with NIOSH 
SEC-00167 03-24-10 Rev. 0 Downey Facility

13 of 77

findings that a routine bioassay program was not initiated until August 1958 at SSFL-Area IV 

(NIOSH, 2009).

The NOCTS database was reviewed for claimants whose work history included the Downey Facility 

during part or all of the covered period (1948 through 1955). A total of 33 claimants were identified. 

The files for all 33 claimants were thoroughly reviewed and no internal monitoring data were found. 

This is consistent with the above determination that insufficient monitoring existed and that only very 

limited internal monitoring data are available to NIOSH until after 1958.

5.4 External Personnel Monitoring Data

NIOSH has access to limited photon, beta, and neutron external dosimetry results, as well as other 

supporting data, for the entire period evaluated in this report (available for all years of site operation). 

The policy at SSFL-Area IV was to assign the applicable dosimetry to anyone with the potential for 

photon, beta, or neutron exposure; it was assigned based on job assignments that required exposure to 

radioactive materials (NIOSH, 2009; ORAUT-TKBS-0038-6). AERD operations comprised only a 

small portion of the overall activities at the Downey Facility during this time period; therefore, the 

majority of personnel were not radiation workers. Summaries of the available external monitoring 

data can be found in the NIOSH evaluation report for Area IV of the Santa Susanna Field Laboratory, 

SEC Petition Evaluation Report, Petition SEC-00093 (NIOSH, 2009). Details regarding the various 

analyses used, and the associated minimum detectable activities, are presented in Atomics 

International – Occupational External Dose (ORAUT-TKBS-0038-6).

5.5 Workplace Monitoring Data

NIOSH only has access to limited workplace air, surface, and environmental monitoring data for the 

entire Downey Facility operations period (Monitoring, 1952; Monitoring, 1954-1955). The data 

available are inadequate for sufficiently accurate dose reconstructions in the absence of personnel 

monitoring data. 

5.6 Radiological Source Term Data

The diverse reactor, accelerator, and support operations at the Downey Facility resulted in potential 

exposures to fission products and transuranics. The source term and activity data available to NIOSH 

for the years of DOE operation (1948 through 1955) are inadequate for sufficiently accurate dose 

reconstructions in the absence of personnel or workplace monitoring data.

 

6.0 Feasibility of Dose Reconstruction for the Proposed Class

42 C.F.R. § 83.14(b) states that HHS will consider a NIOSH determination that there was insufficient 

information to complete a dose reconstruction, as indicated in this present case, to be sufficient,

without further consideration, to conclude that it is not feasible to estimate the levels of radiation 

doses of individual members of the class with sufficient accuracy.

In the case of a petition submitted to NIOSH under 42 C.F.R. § 83.9(b), NIOSH has already 

determined that a dose reconstruction cannot be completed for an employee at the DOE or AWE 

facility. This determination by NIOSH provides the basis for the petition by the affected claimant. 

Per § 83.14(a), the NIOSH-proposed class defines those employees who, based on completed 

research, are similarly affected and for whom, as a class, dose reconstruction is similarly not feasible.

In accordance with § 83.14(a), NIOSH may establish a second class of co-workers at the facility for 

whom NIOSH believes that dose reconstruction is similarly infeasible, but for whom additional 

research and analysis is required. If so identified, NIOSH would address this second class in a 

separate SEC evaluation rather than delay consideration of the claim currently under evaluation (see 

Section 10). This would allow NIOSH, the Board, and HHS to complete, without delay, their 

consideration of the class that includes a claimant for whom NIOSH has already determined a dose 

reconstruction cannot be completed, and whose only possible remedy under EEOICPA is the addition 

of a class of employees to the SEC.

This section of the report summarizes research findings by which NIOSH determined that it lacked 

sufficient information to complete the relevant dose reconstruction and on which basis it has defined 

the class of employees for which dose reconstruction is not feasible. NIOSH’s determination relies on 

the same statutory and regulatory criteria that govern consideration of all SEC petitions. 

6.1 Feasibility of Estimating Internal Exposures

NIOSH has evaluated the available personnel and workplace monitoring data and source term 

information and has determined that there are insufficient data for estimating internal exposures, as 

described below.

As presented in Section 3.0 of this report, HHS has designated an SEC class for SSFL-Area IV 

workers for the period from January 1, 1955 through December 31, 1958 (HHS, 2009). In the 

associated evaluation report, SEC Petition Evaluation Report, Petition SEC-00093 (NIOSH, 2009), 

NIOSH determined that inadequate routine bioassay monitoring program existed for SSFL-Area IV 

through 1958. NIOSH similarly determined in its evaluation of petition SEC-00151 (NIOSH, 2010a) 

that the Canoga Avenue Facility also lacked an adequate routine bioassay monitoring program during 

its entire period of operations from 1955 through 1960, resulting in a NIOSH-proposed SEC class that 

includes DOE employees who worked at the Canoga Avenue Facility from January 1, 1955 through 

December 31, 1960.

The Downey Facility originated many of the radiological practices and record-keeping programs 

subsequently employed at the SSFL-Area IV and Canoga Avenue sites when operations were 

transferred from the Downey Facility in 1955. This resulted in a continuity of the program limitations

(e.g., no bioassay monitoring done before 1958) that are evident in the collective health physics 

records for the ETEC-related sites. Despite extensive research into each of the ETEC-related sites, 

NIOSH has found no evidence of an adequate bioassay monitoring program during DOE operational 

years at the Downey Facility (1948 through 1955). This NIOSH finding is consistent with the dose 

reconstruction infeasibility findings beginning in 1955 for the SSFL-Area IV and Canoga Avenue 

facilities (NIOSH, 2009; NIOSH, 2010a).
SEC-00167 03-24-10 Rev. 0 Downey Facility

NIOSH does not have access to sufficient personnel monitoring, workplace monitoring, or source 

term data to estimate potential internal exposures to fission products and other radionuclides at the 

Downey Facility during the period from January 1, 1948 through December 31, 1955. Consequently, 

NIOSH finds that it is not feasible to estimate, with sufficient accuracy, internal exposures to fission 

products and other radionuclides and resulting doses for the class of employees covered by this 

evaluation.

Although NIOSH found that it is not possible to completely reconstruct internal radiation doses for the 

period from January 1, 1948 through December 31, 1955, NIOSH intends to use any internal 

monitoring data that may become available for an individual claim (and that can be interpreted using 

existing NIOSH dose reconstruction processes or procedures). Dose reconstructions for individuals 

employed at the Downey Facility during the period from January 1, 1948 through December 31, 1955, 

but who do not qualify for inclusion in the SEC, may be performed using these data as appropriate.

6.2 Feasibility of Estimating External Exposures

This evaluation responds to a petition based on NIOSH determining that internal radiation exposures

to fission products and other radionuclides could not be reconstructed for a dose reconstruction 

referred to NIOSH by the Department of Labor (DOL). As noted above, HHS will consider this 

determination to be sufficient without further consideration to determine that it is not feasible to 

estimate the levels of radiation doses of individual members of the class with sufficient accuracy. 

Consequently, it is not necessary for NIOSH to fully evaluate the feasibility of reconstructing external 

radiation exposures for the class of workers covered by this report.

NIOSH has determined that it has access to sufficient personnel monitoring and workplace monitoring 

data to either: (1) estimate the maximum external radiation dose for every type of cancer for which 

radiation doses are reconstructed that could have been incurred under plausible circumstances by any 

member of the class; or (2) estimate the external radiation doses to members of the class more 

precisely than a maximum dose estimate.

Adequate reconstruction of medical dose is likely to be feasible by using claimant-favorable 

assumptions in the technical information bulletin, Dose Reconstruction from Occupationally Related 

Diagnostic X-Ray Procedures (ORAUT-OTIB-0006), and site profile documents associated with the 

ETEC-related sites (ORAUT-TKBS-0038).

6.3 Class Parameters Associated with Infeasibility

Consistent with the NIOSH findings for the SSFL-Area IV site (NIOSH, 2009) and the Canoga 

Avenue Facility (NIOSH, 2010a), NIOSH has found no evidence of an adequate bioassay monitoring 

program during DOE operational years at the Downey Facility (1948 through 1955). NIOSH has 

therefore recommended that the proposed SEC class for the Downey Facility include the entire DOE 

operations period from January 1, 1948 through December 31, 1955.

As discussed in Section 4.4, NIOSH is unable to define individual worker exposure scenarios based 

on specific work locations at the Downey Facility. Therefore, NIOSH recommends that the class 

definition include the entire Downey Facility during the specified time period.
SEC-00167 03-24-10 Rev. 0 Downey Facility

16 of 77

NIOSH has found insufficient documentation associating job titles and/or job assignments with 

specific radiological operations or conditions. Without such information, NIOSH is unable to define 

the proposed SEC class based on worker job descriptions or the availability of individual monitoring 

data. NIOSH therefore recommends that the proposed class definition include all employees of the 

Department of Energy, its predecessor agencies, and their contractors and subcontractors who worked 

at the Downey Facility during the specified time period, regardless of whether a worker was 

monitored for radiation exposure.

7.0 Summary of Feasibility Findings for Petition SEC-00167

This report evaluates the feasibility for completing dose reconstructions for employees at the Downey 

Facility from January 1, 1948 through December 31, 1955. NIOSH determined that members of this 

class may have received radiation exposures from intakes of fission products and other radionuclides. 

NIOSH lacks sufficient information, which includes biological monitoring data, sufficient air 

monitoring information, or sufficient process and radiological source information that would allow it 

to estimate the potential internal exposures to which the proposed class may have been exposed.

NIOSH has documented herein that it cannot complete the dose reconstructions related to this petition. 

The basis of this finding demonstrates that NIOSH does not have access to sufficient information to 

estimate either the maximum radiation dose incurred by any member of the class or to estimate such 

radiation doses more precisely than a maximum dose estimate.

Although NIOSH found that it is not possible to completely reconstruct radiation doses for the period 

from January 1, 1948 through December 31, 1955, NIOSH intends to use any internal or external 

monitoring data that may become available for an individual claim (and that can be interpreted using 

existing NIOSH dose reconstruction processes or procedures). Dose reconstructions for individuals 

employed at the Downey Facility during the period from January 1, 1948 through December 31, 1955, 

but who do not qualify for inclusion in the SEC, may be performed using these data as appropriate.

8.0 Evaluation of Health Endangerment for Petition SEC-00167

The health endangerment determination for the class of employees covered by this evaluation report is 

governed by EEOICPA and 42 C.F.R. § 83.14(b) and § 83.13(c)(3). Pursuant to these requirements, if 

it is not feasible to estimate with sufficient accuracy radiation doses for members of the class, NIOSH 

must determine that there is a reasonable likelihood that such radiation doses may have endangered 

the health of members of the class. The regulations require NIOSH to assume that any duration of 

unprotected exposure may have endangered the health of members of a class when it has been 

established that the class may have been exposed to radiation during a discrete incident likely to have 

involved levels of exposure similarly high to those occurring during nuclear criticality incidents. If 

the occurrence of such an exceptionally high-level exposure has not been established, then NIOSH is 

required to specify that health was endangered for those workers who were employed for a number of 

work days aggregating at least 250 work days within the parameters established for the class or in 

combination with work days within the parameters established for one or more other classes of 

employees in the SEC. 
SEC-00167 03-24-10 Rev. 0 Downey Facility

17 of 77

NIOSH has determined that members of the class were not exposed to radiation during a discrete 

incident likely to have involved levels of exposure similarly high to those occurring during nuclear 

criticality incidents. However, the evidence reviewed in this evaluation indicates that some workers in 

the class may have accumulated chronic radiation exposures through intakes of fission products and 

other radionuclides and from direct exposure to radioactive materials. Consequently, NIOSH is 

specifying that health was endangered for those workers covered by this evaluation who were 

employed for a number of work days aggregating at least 250 work days within the parameters 

established for this class or in combination with work days within the parameters established for one 

or more other classes of employees in the SEC.

9.0 NIOSH-Proposed Class for Petition SEC-00167

The evaluation defines a single class of employees for which NIOSH cannot estimate radiation doses 

with sufficient accuracy. This class includes all employees of the Department of Energy, its 

predecessor agencies, and their contractors and subcontractors who worked at the Downey Facility in 

Los Angeles County, California, from January 1, 1948 through December 31, 1955, for a number of 

work days aggregating at least 250 work days, occurring either solely under this employment or in 

combination with work days within the parameters established for one or more other classes of 

employees included in the Special Exposure Cohort.

10.0 Evaluation of Second Similar Class

In accordance with § 83.14(a), NIOSH may establish a second class of co-workers at the facility, 

similar to the class defined in Section 9.0, for whom NIOSH believes that dose reconstruction may not 

be feasible, and for whom additional research and analyses are required. If a second class is 

identified, it would require additional research and analyses. Such a class would be addressed in a 

separate SEC evaluation rather than delay consideration of the current claim. At this time, NIOSH has 

not identified a second similar class of employees at the Downey Facility for whom dose 

reconstruction may not be feasible.
