The Honorable Michael O. Leavitt
Secretary of Health and Human Services
Department of Health and Human Services

Dear Mr. Secretary:

The Advisory Board on Radiation and Worker Health (The Board) has
evaluated SEC Petition-00033 concerning workers at the Oak Ridge
Institute of Nuclear Studies (ORINS) under the statutory requirements
established by EEOICPA and incorporated into 42 CFR Sec. 83.13 (c)
(1) and 42 CFR Sec. 83.13 (c) (3). The Board respectfully
recommends a Special Exposure Cohort (SEC) be accorded to all
employees of the DOE or DOE contractors or subcontractors who were
monitored or should have been monitored while working at Oak Ridge
Institute of Nuclear Studies Cancer Research Hospital from May 15,
1950 through December 31, 1963 and who were employed for a
number of work days aggregating at least 250 work days during the
period from May 15, 1950 through December 31, 1963 or in
combination with work days within the parameters established for one
or more other classes of employees in the SEC

This recommendation is based on the following factors:

This facility conducted research on the use of various radioactive
isotopes for the treatment of cancer. People working in this facility
were exposed to these radioactive materials through a number of
work activities. Although there was the potential for substantial
internal exposures arising from preparing, administering, and
disposing of radioisotopes and radioactive waste, NIOSH found no
evidence of personal or workplace monitoring that could be used to
bound internal radiation exposures. As a result of these

limitations, NIOSH cannot establish a maximum internal exposure
scenario that addresses all of the internal exposure potential for the
petitioning class, and therefore, cannot estimate internal doses for
this class with sufficient accuracy. The Board concurs with this
determination.


The Honorable Michael O. Leavitt October 11, 2006

e NIOSH determined that health was endangered for the workers at Oak Ridge Institute of
Nuclear Sciences Cancer Research Hospital exposed to radiation at this facility during
the time period in question. The Board concurs with this determination.

e The NIOSH review of the data was found that it was sufficient to support accurate
individual dose reconstruction for external doses and occupational medical doses for
workers at the ORINS Cancer Research Hospital. The Board concurs with this
determination.

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