LOOKING AT THE DATA TABLE ON THE CASUALTIES OF THE BOMB

TABLE A: Estimates of Casualties (anyone killed or hurt in a war or disaster)
	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 (those dead)  at Various Distances
Distance from X, in feet	Percent Mortality (death rate)
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
