TABLE 1.

The total amount of radiation held constant at a level that results in 100% lethality when given to one person (700 J or about 10 Gy) and the population size increased.

Number of People	Dose/Person (Gy)	Amount/Person (J)	Amount (J)	Background Cancer	Excess Cancer
1	10	*700	700	.42	0.0
10	1	70	700	4.2	1.0
100	0.1	7	700	42	1.0
1,000	0.01	0.7	700	420	1.0
10,000	**0.001	0.07	700	4,200	1.0
100,000	0.0001	0.007	700	42,000	1.0

^*This is a large lethal amount of radiation given to one person. Cancer can never be detected with this amount of radiation regardless of population size!

^**Background low LET dose/person
