"PVT Adams’ Preburst Environment
Adams’ foxhole is located to the east of the village. The point of burst is only 500 meters
(1,650 feet) to the northeast of his position. Although he survives the blast and thermal
effects due to shielding from the walls of his foxhole, his protection is insufficient to save
him from receiving a dose of ionizing radiation that will eventually kill him. The environment
he is subjected to is extremely intense. Although he temporarily and partially recovers
from the immediate effects of the detonation, his impressions remain blurred and confused.
The following describes Adams’ observations:
0-2 Seconds The flash of light is like that seen by Carter and Baker; Adams ducks lower
and crouches in the foxhole. Like the others, he is temporarily blinded and the subsequent
events happen so rapidly that he is unable to tell exactly what is happening. The heat
wave passes over the foxhole. Indirect thermal radiation reflected from the haze and
clouds penetrates Adams’ uniform; he feels a searing pain as his back is burned. His uni-
form is heavily scorched, but does not ignite.
2-3 Seconds Immediately on the heels of the heat wave, the blast and winds arrive. The
ground shakes violently, slamming Adams against the sides of his foxhole. The foxhole
partially collapses, throwing dirt and other debris on top of him. Shocked and
dazed.. unable to see due to the blinding bright light, Adams is only dimly aware of
the high wind and its effects. He has excruciating pain in both ears and his nose is
bleeding profusely. He does not see the tree that has blown down and partially covers his
foxhole, nor does he see the soldier—hurled through the air as if lifted by some unseen
hand—passing directly over his foxhole.
3 Seconds - 1 Hour Dazed and in shock, Adams remains crouched in his foxhole. After a
few minutes, he crawls from beneath the smoldering tree and out of his foxhole into a
scene of smoke, fires, dust, and overturned and scattered equipment. Several bodies lie
alongside trees and vehicles, hurled there by the violence of the explosion. Soldiers who
miraculously survived are in various stages of shock and pain from burns and other
wounds. Some are bleeding from the ears, their eardrums ruptured. Most are vomiting.
Prone bodies are nearby. Some are completely charred black on one side of their body.
Adams’ head aches and he is sweating profusely. He feels the onset of nausea and be-
gins to vomit. He feels weak. Later, while he is waiting his turn for medical help, he hears
that one of the soldiers’ dosimeters is pegged at 600 cGy...the maximum reading of the IM-
93. He has no way of knowing if he has received a dose greater than that.
The physical environment at Adams’ fox hole. The weapon effects at Adams’ foxhole in
quantitative terms are as follows:
Prompt radiation: 3,000 cGy. (Actual radiation outside of Adams’ foxhole was 11,650
cGy. Foxhole provided Adams a protection factor of 3.)
Thermal radiation: 21 calories per square centimeter that arrives within 1.2 seconds.
This is enough to immediately ignite painted surfaces and cause 100 percent casualties for
exposed persons.
Overpressure: 7.4 pounds per square inch arriving at 2 seconds after detonation and last-
ing for approximately 1 second.
Dynamic pressure (wind): hurricane-force winds causing a 165-pound standing soldier
to attain a velocity of 60 feet per second (35 miles per hour) by the time he has moved 10
feet from his original position.
