Dear Madam Secretary:

The Advisory Board on Radiation and Worker Health (The Board) has 

evaluated SEC Petition-00163 concerning workers at the Lawrence 

Livermore National Laboratory (LLNL) in Livermore, California under the 

statutory requirements established by EEOICPA and incorporated into 42 

CFR Sec. 83.14. The Board respectfully recommends Special Exposure 

Cohort (SEC) status be accorded to all employees of the Department of 

Energy, its predecessor agencies, and their contractors or subcontractors 

who worked at the Lawrence Livermore National Laboratory in Livermore, 

California from January 1, 1950 through December 31, 1973, 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 in the 

Special Exposure Cohort. 

This recommendation is based on the following factors:

• Individuals working at LLNL during the time period in question 

worked on research and production activities related to nuclear 

weapons production.

• The NIOSH review of available monitoring data as well as 

available source term information found that NIOSH lacked 

adequate information necessary to conduct accurate individual 

dose reconstructions for internal doses from exposures to mixed 

fission and activation products during the time period in question. 

The Board concurs with this determination.

• NIOSH determined that health may have been endangered for 

these LLNL facility workers. The Board concurs with this 

determination.
