. How much is the increase in radioactivity compared to the general variations in the amount of radioactivity from place to place? The amounts of background radioactivity in a wooden building and a brick building are quite different, because the wood is less radioactive than the bricks.
It turns out that at the time that I asked this question, the difference in the effects was less than the difference between being in a brick and a wooden building. And the difference between being at sea level and being at 5000 feet altitude was a hundred times, at least, bigger than the extra radioactivity produced by the atomic bomb testing.
Now, I say that if a man is absolutely honest and wants to protect the populace from the effects of radioactivity, which is what our scientific friends often say they are trying to do, then he should work on the biggest number, not on the smallest number, and he should try to point out that the radioactivity which is absorbed by living in the city of Denver is so much more serious, is a hundred times bigger than the background from the bomb, that all the people of Denver ought to move to lower altitudes. The situation really is—don't get frightened if you live in Denver—it's small. It doesn't make much difference. It's only a tiny effect. But the effect from the bombs is less than the difference between being at low level and high level, I believe. I'm not absolutely sure
