How many were killed as a direct and indirect result of Hiroshima and Nagasaki?

Answer 1

Figures can be disputed but here goes --

and to the figures below you can throw in an even hundred thousand for subsequent claims to lingering effects of radiots etc over the years all subjective to various interetations.

"""There has been great difficulty in estimating the total casualties in the Japanese cities as a result of the atomic bombing. The extensive destruction of civil installations (hospitals, fire and police department, and government agencies) the state of utter confusion immediately following the explosion, as well as the uncertainty regarding the actual population before the bombing, contribute to the difficulty of making estimates of casualties. The Japanese periodic censuses are not complete. Finally, the great fires that raged in each city totally consumed many bodies.

The number of total casualties has been estimated at various times since the bombings with wide discrepancies. The Manhattan Engineer District's best available figures are:

TABLE A: Estimates of Casualties Hiroshima Nagasaki
Pre-raid population 255,000 195,000
Dead 66,000 39,000
Injured 69,000 25,000
Total Casualties 135,000 64,000

The relation of total casualties to distance from X, the center of damage and point directly under the air-burst explosion of the bomb, is of great importance in evaluating the casualty-producing effect of the bombs. This relationship for the total population of Nagasaki is shown in the table below, based on the first-obtained casualty figures of the District:

TABLE B: Relation of Total Casualties to Distance from X Distance from X,
feet Killed Injured Missing Total
Casualties Killed
per square mile
0 - 1,640 7,505 960 1,127 9,592 24,7OO
1,640 - 3,300 3,688 1,478 1,799 6,965 4,040
3,300 - 4,900 8,678 17,137 3,597 29,412 5,710
4,900 - 6,550 221 11,958 28 12,207 125
6,550 - 9,850 112 9,460 17 9,589 20

No figure for total pre-raid population at these different distances were available. Such figures would be necessary in order to compute per cent mortality. A calculation made by the British Mission to Japan and based on a preliminary analysis of the study of the Joint Medical-Atomic Bomb Investigating Commission gives the following calculated values for per cent mortality at increasing distances from X:

TABLE C: Percent Mortality at Various Distances Distance from X,
in feet Percent Mortality
0 - 1000 93.0%
1000 - 2000 92.0
2000 - 3000 86.0
3000 - 4000 69.0
4000 - 5000 49.0
5000 - 6000 31.5
6000 - 7000 12.5
7000 - 8000 1.3
8000 - 9000 0.5
9000 - 10,000 0.0

It seems almost certain from the various reports that the greatest total number of deaths were those occurring immediately after the bombing. The causes of many of the deaths can only be surmised, and of course many persons near the center of explosion suffered fatal injuries from more than one of the bomb effects. The proper order of importance for possible causes of death is: burns, mechanical injury, and gamma radiation. Early estimates by the Japanese are shown in D below:

TABLE D: Cause of Immediate Deaths Hiroshima
Cause of Death Percent of Total
Burns 60%
Falling debris 30
Other 10



Nagasaki
Cause of Death Percent of Total
Burns 95%
Falling debris 9
Flying glass 7

Answer 2

it is estimated that as many as 140,000 had died in Hiroshima by the bomb and its associated effects, with the estimate for Nagasaki roughly 74,000. In both cities, the overwhelming majority of the deaths were those of civilians.

Answer 3

about 140 000 in hiroshima and about 74 000 in nagasaki

Answer 4

Hiroshima 66,000 dead and 69,000 injured
Nagasaki 195,000 dead and 25,000 injured

Thats a total of 261,000 casualties not considering that the 94,000 injured suffered and some are walking dead.

Answer 5

Not nearly as many as we're saved through not having endless conventional e.g., firebombing and HE air raids and a ground force invasion of the Japanese homeland.
