I. Summary of Results

This update to the Report on Residual Radioactive and Beryllium Contamination at Atomic 

Weapons Employer (AWE) facilities and Beryllium Vendor facilities is the fourth revision to the 

original study reported in November 2002 and revised in October 2003, December 2006, and 

October 2009.

The National Institute for Occupational Safety and Health (NIOSH) has reviewed all AWE 

facilities and all Beryllium Vendor facilities that were posted on the Department of Energy’s

(DOE) Office of Health, Safety and Security (OHSS) website. NIOSH evaluated information that 

has been identified since NIOSH’s last report. The documents reviewed did not indicate the 

existence of a current, unrecognized occupational or public health threat. NIOSH also based its 

findings on information posted on the DOE OHSS website as of March 1, 2011 (changes made 

to the DOE OHSS website after March 1, 2011 are not reflected in this report).

In cases where additional information was identified, the potential for significant residual 

contamination was re-evaluated.

The results for the 203 AWEs evaluated are as follows:

 2 of the previously listed AWE facilities are no longer listed as AWEs. The remaining 201

facilities were evaluated.

 98 of the 201 AWE facilities have little potential for significant residual contamination 

outside of the periods in which weapons-related production occurred.

 103 of the 201 AWE facilities have the potential for significant residual contamination 

outside of the periods in which weapons-related production occurred.

Changes in AWE facilities since the last revision of this report:

 The end dates of residual contamination periods for 40 of the AWEs were listed as “present” 

in the previous revision of this report. Because that revision was issued in October, 2009, 

“present” was defined as October 2009. These 40 facilities still have end dates of residual 

contamination periods listed as “present” in this version of the report. Therefore, these end 

dates will be extended to March 1, 2011.

II. Background and Purpose

The Energy Employees Occupational Illness Compensation Program Act of 2000 (EEOICPA),

42 U.S.C. §§ 7384-7385, established a program to compensate individuals who developed 

illnesses as a result of their employment in nuclear weapons production-related activities at 

certain facilities in which radioactive materials or beryllium was processed. DOE was directed 

by Executive Order 13,179 to publish in the Federal Register a list of facilities covered by

EEOICPA. On January 17, 2001, DOE published a list of AWEs, DOE facilities, and beryllium

vendors in the Federal Register (66 Fed Reg. 4003).Updates to the list (corrections, additions,

and deletions) are made periodically by DOE; ten updates have been published since the initial 

list was published. This update to the Report on Residual Radioactive and Beryllium 

Contamination at Atomic Weapons Employer Facilities and Beryllium Vendor Facilities is the 

fourth revision to the original report. The report was first issued in November 2002, and updated 

and reissued in June 2004, December 2006 and October 2009.

The DOE OHSS website, 

(http://www.hss.energy.gov/healthsafety/fwsp/advocacy/faclist/findfacility.cfm) provides 

synopses of the work performed at each facility, including a listing of periods during which DOE 

believes, based on current information, that weapons-related processing was conducted. In 

determining these periods, DOE has applied the definitions in EEOICPA to the known facts 

about the time and conditions of weapons-related processing at each facility. DOE revises the 

entries in its database as additional information is obtained. These periods are referred to in this 

report as “periods in which weapons-related production occurred.” It should be noted that the 

Department of Labor (DOL) has assumed responsibility for determining actual periods of 

covered employment, based upon DOE’s findings as well as information from claimants and 

other sources.

This study consisted primarily of an evaluation of documents pertaining to AWEs. These include 

documents compiled by DOE OHSS, documents obtained through NIOSH data capture efforts,

and documents located on the Formerly Utilized Sites Remediation Action Program (FUSRAP)

and U.S. Army Corps of Engineers websites. NIOSH also requested documents from state and 

local authorities. The quantity and quality of the information available for each site varied 

substantially. Examples of documentation reviewed include radiological surveys, descriptions of 

production operations, contractual agreements, and interoffice correspondence. 

NIOSH believes that contamination levels at designated facilities in excess of those indicated in 

10 C.F.R. pt. 835, Appendix D (Occupational Radiation Protection, Surface Contamination 

Values), indicate that there is “significant contamination” remaining in those facilities.

Available documentation for each facility was reviewed to determine if there was an indication 

that residual radioactive contamination was present outside of the periods in which weaponsrelated production occurred. Those levels were then compared to current radiation protection 

limits listed in 10 C.F.R. pt. 835 to determine if there was “significant contamination.” If there 

was no, or limited, documentation on radiation levels at specified facilities, NIOSH made a 
Page 5 of 10

professional judgment regarding the residual contamination. If NIOSH determined there was 

“the potential for significant contamination” at a designated facility, then NIOSH determined, 

pursuant to the requirements of the National Defense Authorization Act for Fiscal Year 2005 

(NDAA) (Pub. L. 108-375), that “it is at least as likely as not that such contamination could have 

caused an employee who was employed at such facility only during the residual contamination 

period to contract a cancer.” 

In the case of beryllium contamination, if there was no evidence that the beryllium areas had 

been decontaminated, it was determined that “it is at least as likely as not that such 

contamination could have caused an employee who was employed at such facility only during 

the residual contamination period to contract a beryllium illness.” Because beryllium 

sensitization can occur at very low levels of exposure, the level of residual beryllium 

contamination remaining was not considered in the determination.

During the course of the radiation dose reconstruction process, data capture efforts were focused 

on processes and conditions relative to radioactive materials. Therefore, data associated with 

beryllium were not intentionally sought or captured.

Some of the periods in which weapons-related production occurred have been changed on the 

DOE OHSS website since the previous NIOSH report. Appendices A-1 and B-1 provide the 

current status and evaluations for all AWE and Beryllium Vendor facilities, respectively.

Appendices A-2 and B-2 provide descriptions of each facility, the data reviewed as a part of this 

evaluation, and the final findings. 

Periods of Residual Contamination

The evaluations focused on determining whether the potential for significant residual 

contamination existed outside of the periods in which weapons-related production occurred. In 

many cases, no records of decontamination were found. In others, surveys performed outside of 

the period in which weapons-related production occurred indicated the existence of significant 

residual contamination. However, some of the documentation provided dates of 

decontamination, dates of demolition of the facility, or descriptions of the radiological controls 

in place during operations. For sites that exhibited a potential for significant residual radioactive 

contamination outside of the periods in which weapons-related production occurred, and for 

which an indication of a more accurate period was available, this time period was provided. For 

sites that exhibited a potential for significant residual radioactive contamination outside of the 

periods in which weapons-related production occurred and for which an indication of a more 

accurate period was not available, NIOSH assumed that significant residual contamination 

existed until the time which the facility was demolished or until the present time (defined as the 

date this report was written).

Some sites performed work with radioactive material and/or beryllium for commercial purposes, 

in addition to work for the Atomic Energy Commission (AEC)/DOE. When it was impossible to 

distinguish residual contamination resulting from AEC/DOE activities from the contamination

resulting from commercial activities, NIOSH assumed that the contamination was attributable to 

weapons-related activities.

III. Residual Radioactive Contamination Evaluation

This study consisted primarily of an evaluation of documents pertaining to AWEs. These include 

documents compiled by DOE OHSS, documents obtained through data capture efforts of 

NIOSH, and documents located on the FUSRAP and U.S. Army Corps of Engineers websites. In 

all cases, the individual site finding is based on the available information. The finding on any 

single site was based on the quantity and completeness of the information available regarding 

that site and professional judgment as necessary. 

In this evaluation of residual radioactive contamination, as in the previous report, the following 

factors were considered:

1) The radionuclides involved;

2) The quantity of radioactive material processed;

3) The physical form of the radioactive material processed (i.e., solid, liquid, or gas);

4) The operations performed and their potential for radiation/radioactivity exposure;

5) Documented radiological control and monitoring programs that were in place during 

operations; and

6) Documented decontamination of facilities

These factors were used to estimate the potential for radiation exposure both during operations 

and after production/processing had ceased. For example, a facility for which a decontamination 

survey was documented was classified as having little potential for residual radioactive 

contamination after the decontamination date, while a facility with a high potential for residual 

radioactive contamination during operations and no documented decontamination data was 

classified as having a potential for residual contamination after operations had ceased. 

Each site was assigned to one of two categories:

1. Documentation reviewed indicates there is little potential for significant residual 

contamination outside the period in which weapons-related production occurred.

A site was assigned to this category if the documentation available for the facility 

indicated one or more of the following characteristics:

a) The facility was decontaminated within the periods in which weapons-related 

production occurred;

b) The facility had very little potential for residual contamination during actual 

operations; or 

c) The facility is still in operation and the end date is listed as “present.” 

2. Documentation reviewed indicates there is a potential for significant residual 

contamination outside the period in which weapons-related production occurred.

A site was assigned to this category if there was documentation indicating the following:

a) Radioactive material was present in quantities or forms such that it is more likely 

than not that such contamination could have caused an employee who was 
Page 8 of 10

employed at such facility only during the residual contamination period to 

contract a cancer; and

b) Radioactive material was processed or present outside of the dates listed on the 

DOE OHSS website.

This type of documentation often included FUSRAP surveys conducted after Manhattan

Engineer District (MED)/AEC/DOE operations were complete, which indicated the presence of

residual radioactive contamination that could be attributed to those activities.

In some cases, the facilities processed radioactive material not only for nuclear weapons 

production, but also for commercial, non-DOE contracts. Sometimes the material processed for 

nuclear weapons production was indistinguishable from material processed for commercial 

purposes. Wherever residual radioactive contamination due to DOE operations was not clearly 

distinguishable from that resulting from commercial operations, NIOSH assumed that the 

contamination was the result of weapons production activities. As a result, in these cases, the 

findings were that the potential for significant residual contamination existed outside of the 

periods in which weapons-related production occurred. For sites that exhibited a potential for 

significant residual radioactive contamination outside of the periods in which weapons-related 

production occurred, and for which an end date could not be determined, NIOSH assumed that 

significant residual contamination existed until the time the facility was demolished or until the 

present time (defined as the date this report was written).

Findings of Evaluation of Facilities for Residual Radioactive Contamination

The results of this study indicate that there are AWE facilities for which the potential for 

significant residual radiological contamination exists outside of the periods in which weaponsrelated production occurred as listed on the DOE OHSS website.

Appendix A-1 lists all of the AWE facilities and the findings for potential residual radioactive 

contamination. Appendix A-2 describes each facility evaluated for residual radioactive 

contamination, the data reviewed as a part of this evaluation, and the ultimate findings.

IV. Residual Beryllium Contamination Evaluation

The primary sources of information used to evaluate each site were the individual facility files 

compiled on the DOE OHSS website. In addition, interviews with current and past employees of 

these facilities were conducted to obtain information not contained in available documentation.

When characterizing facilities for the purpose of radiation dose reconstruction, data capture 

efforts are focused on processes and conditions relative to radioactive materials. Therefore, data 

associated with beryllium were not intentionally sought or captured during this process. The 

beryllium sections of this report therefore reflect mostly an update of dates appearing on the 

DOE OHSS website

http://www.hss.energy.gov/healthsafety/fwsp/advocacy/faclist/findfacility.cfm.
Page 9 of 10

The finding for any single site was based on the quantity and completeness of the information 

available regarding that site and professional judgment as necessary. 

In this evaluation of residual radioactive contamination, as in the previous report, the following 

factors were considered:

1) If beryllium was actually handled at the site; and

2) If there was evidence of decontamination of the facility.

These factors were used to estimate the potential for beryllium exposure both during operations 

and after production/processing had ceased. For example, a facility for which a decontamination 

survey was documented or for which personal interviews indicated that decontamination was 

performed, was classified as having little potential for residual beryllium contamination after the 

decontamination date; a facility without such evidence of decontamination was classified as 

having a potential for residual beryllium contamination after operations had ceased.

Each site was assigned to one of two categories:

1. Documentation reviewed indicates there is little potential for significant residual 

contamination outside the period in which weapons-related production occurred.

A site was assigned to this category if the documentation available for the facility 

indicated one or more of the following characteristics:

a) Evidence of decontamination and/or beryllium contamination survey data;

b) The facility had very little potential for residual contamination during actual 

operations; or

c) The facility is still in operation and the end date is listed as “present.” 

2. Documentation reviewed indicates there is a potential for significant residual 

contamination outside the period in which weapons-related production occurred.

A site was assigned to this category if either of the following conditions existed:

a) Documentation was available indicating that beryllium was processed or present 

outside of the dates listed on the DOE OHSS website, such that it is more likely 

than not that such contamination could have caused an employee who was 

employed at such facility only during the residual contamination period to 

contract a beryllium-related illness; or

b) There was no evidence of decontamination of the facility or area where beryllium 

was processed.

In some cases, the facilities processed beryllium material not only for nuclear weapons 

production, but also for commercial, non-DOE contracts. Sometimes the material processed for 

nuclear weapons production was indistinguishable from material processed for commercial 

purposes. Wherever residual beryllium contamination due to DOE operations was not clearly 

distinguishable from that resulting from commercial operations, NIOSH assumed that the 
Page 10 of 10

contamination was the result of weapons production activities. As a result, in these cases, the 

findings were that the potential for significant residual contamination existed outside of the 

periods in which weapons-related production occurred. For sites that exhibited a potential for 

significant residual beryllium contamination outside of the periods in which weapons-related 

production occurred, and for which an end date could not be determined, NIOSH assumed that 

significant residual contamination existed until the time the facility was demolished or until the 

present time (defined as the date this report was written).

Findings of Evaluation of Facilities for Residual Beryllium Contamination

The results of this study are that there are Beryllium Vendor facilities for which the potential for 

significant residual beryllium contamination exists outside of the periods in which weaponsrelated production occurred as listed on the DOE OHSS website. 

Appendix B-1 lists all Beryllium Vendor facilities and the findings for potential residual 

beryllium contamination. Appendix B-2 describes each facility evaluated for residual beryllium

contamination, the data reviewed as a part of this evaluation, and the ultimate findings.

V. Conclusions

The findings of this study are as follows:

1.) Some AWE facilities and beryllium vendor facilities have the potential for significant 

residual radiological and beryllium contamination outside of the periods in which weaponsrelated production occurred.

2.) For the purposes of this report, NIOSH believes that for facilities having “significant 

contamination” it is at least as likely as not that such contamination could have caused an 

employee who was employed at such facility only during the residual contamination period to 

contract a cancer or beryllium illness.

3.) The documents reviewed did not indicate the existence of a current, unrecognized 

occupational or public health threat.
