The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from U. S. Project Trinity Report by Carl Maag and Steve Rohrer: located. Subsequent ground surveys of this area found no gamma
intensities higher than 0.02 R/h (1).
Gamma radiation levels at and around ground zero were much higher than
in other onsite areas because of induced activity in the soil.
Twenty-four hours after the detonation, the gamma intensity at ground
zero was estimated to be 600 to 700 R/h. This estimate was based on
data provided by the tank crew that drove to ground zero to obtain
soil samples. The intensity decreased to about 2 R/h at 725 meters
from ground zero. Gamma intensities of 0.1 R/h or more were confined
within a circular area extending about 1,100 meters from ground zero
(except in areas of fallout). One week after the shot, the gamma
