— Dear Mr. Secretary:

Richland, Washington

Bradley P. Clawson The Advisory Board on Radiation and Worker Health (The Board) has

Rexburg, Idaho evaluated SEC Petition-0079 concerning workers at the Dow Chemical
‘diced ti Goon Company site in Madison, Illinois under the statutory requirements
Franklin, Ohio established by EEOICPA and incorporated into 42 CFR Sec. 83.13 and
Mark A. Griffon 42 CFR Sec. 83.14. The Board respectfully recommends Special
Salem, New Hampshire Exposure Cohort (SEC) status be accorded to all AWE employees who
James E. Lockey, M.D. were monitored or should have been monitored for exposure to thorium
Cincinnati, Ohio radionuclides while working at the Dow Chemical Company Madison
Site for a number of work days aggregating at least 250 work days during
“aibeny, Now Yer the period from January 1, 1957 through December 31, 1960, or in
Wanda 1. Munn combination with work days within the parameters established for one or
Richland, Washington more other classes of employees in the SEC. The Board notes that
John W. Poston, Sr., Ph.D. although NIOSH found that they were unable to completely reconstruct
College Station, Texas radiation doses for these employees, they believe that they are able to
Robert W. Presley reconstruct components of the internal dose including uranium, external
Clinton, Tennessee exposures from all radionuclides except Thorium, and occupational
Genevieve S. Roessier, Ph.D. medical doses for this class of workers, and therefore individuals with
Elysian, Minnesota non-presumptive cancers may be considered for partial dose
reconstructions.

Bosque Farm, New Mexico

This recommendation is based on the following factors:

STAFF: e People working at the Dow Chemical Company Madison Site
en were involved in various industrial operations involving uranium
and thorium.
Lewis V. Wade, Ph.D
Washington: 0° © The NIOSH review of the available monitoring data found that
there were not sufficient data available to estimate the internal
SOMMITIEE MANAGEMENT: and external doses from exposure to Thorium. Therefore,
LaShawn D. Shields NIOSH concluded that individual dose reconstructions are not
Atianta, Georgia feasible for people working in this facility during the time period

in question. The Board concurs with this conclusion.


The Honorable Michael O. Leavitt May 23, 2007

e NIOSH determined that health may have been endangered for workers at the Dow
Chemical Company Madison Site during the time period in question. The Board
concurs with this determination.

Enclosed is supporting documentation from the recent Advisory Board Meeting held in
Denver, Colorado where this special exposure cohort class was discussed. If any of these
items are unavailable at this time, they will follow shortly.

Sincerely,
