In no cases, however, were film badge data used in the dose calculations;
rather, they have been and continue to be used solely for comparison with and
validation of the calculations.

In virtually all cases, comparison has been

favorable and within the confidence limits established by the uncertainty
analysis of each calculation.

RESULTS OF DOSE RECONSTRUCTIONS.
Dose reconstructions have been completed for all operations for which

there is no film badge dosimetry and there was a reasonably high potential for

significant radiation exposure to large groups or units, such as ship crews or
maneuver troop units.

These reconstructed doses provide, in the absence of

dosimetry, the readings of what would have been recorded on film badges, had
they been worn.

Because film badges did not record neutron doses or doses

from inhaled or ingested radioactive contaminants, doses for these types of
exposures, being much less prominent from a numbers standpoint, are being
reconstructed separately.

REVIEW OF RECONSTRUCTION METHODOLOGY.
The dose reconstruction methodology and processes have been reviewed, in

whole and in part, by several authorities over the entire term of the NTPR
program.

The first NIPR report dealing with dose reconstruction, that for

Task Force WARRIOR at Shot SMOKY (3), was critically reviewed in 1979 by

nationally recognized radiation experts from scientific laboratories, as well
as by the Office of Technology Assessment (at the request of Senator
Cranston), and the Medical Follow-up Agency of the National Research Council,

National Academy of Sciences.

These reviews provided the confidence to

finalize the methodology and to adapt it to many other exposure scenarios.
Other dose reconstructions were subsequently reviewed by committees appointed
by the National Academy of Sciences.

One such review was conducted in 1980-81

of the Hiroshima-Nagasaki dose reconstructions (18, 19), and another review,
that of the entire dose reconstruction effort, was conducted in 1984-85 (20).
In both instances, the reviews judged the dose reconstruction methodology and
processes to have sound scientific merit.

No major deficiencies were noted

that would reflect unfavorably on the technical aspects of the dose reconstruction methodology or on the radiation doses calculated therefrom.
