Results of Calculations of External Gamma
Radiation Exposure Rates from Fallout
and the Related Radionuclide Compositions
Operation Teapot, 1955
ABSTRACT
This report presents data on calculated gamma radiation exposure rates and
ground deposition of related radionuclides resulting from Events that deposited detectable
radioactivity outside the Nevada Test Site complex.
INTRODUCTION
The Events which deposited detectable radioactivity outside the Nevada Test Site complex! are
listed in Table.1.
RESULTS
Results of the calculations of relative external gamma radiation exposure rate and related
radionuclide ground deposition are given in the Appendices. These calculations are described in detail in
Ref. 2. The output of the calculation has 30 decay times, 10 from 1 to 21 h, 10 from 1 to 300 d, and 10 from 1
to 50 y. For each of these times and for zero time there are values of the external gammaradiation exposure
rate normalized to 1 mR/h, 1 m abovethe surface, 12 h after the event, the associated values of uCi/m? for
each radionuclide, and the total uCi/m?.
