Rexburg, idaho Dear Mr. Secretary:
Michael H. Gibson . oo
Franklin, Ohio The Advisory Board on Radiation and Worker Health (The Board) has
ite A. Gritton evaluated SEC Petition-00094 concerning workers at the Horizons,
Salem, New Hampshire Inc. facility in Cleveland, Ohio under the statutory requirements
Janes ELockey; 6.0: established by EEOICPA and incorporated into 42 CFR Sec. 83.13.
Cincinnati, Ohio The Board respectfully recommends Special Exposure Cohort (SEC)
James M. Melius, M.D., Ph.D. status be accorded to all AWE employees who worked at the Horizons,
Albany, New York Inc. facility in Cleveland, Ohio from January 1, 1952 through
ee December 31, 1956 for a number of work days aggregating at least
Richland, Washington 250 work days occurring either solely under this employment or in
John W: Posten; $?./ PRD! combination with work days within the parameters established for one
College Station, Texas or more other classes of employees in the SEC. The Board notes that
Robert W. Presley although NIOSH found that they were unable to completely
Clinton, Tennessee reconstruct radiation doses for these employees for January 1, 1952
Genevieve S, Roessler, Ph.D. through December 31, 1956, they believe that they are able to ,
Elysian, Minnesota reconstruct the external radiation doses and the occupational medical
Phillip Schofield dose during the time period in question. NIOSH also believes that
Bosque Farm, New Mexico they can also reconstruct individual doses during the residual period
(January 1, 1957 to July 31, 2006).
STAFF: This recommendation is based on the following factors:

for the time period from January 1, 1952 through December 31, 1956 throughout
