[ RadSafe ] Fallout: Internal vs. External

Hi: I would like a bit of clarification myself: when you quantify the dosage in 
rem, is this solely the external dose of gamma, or there other contributors?

Dear members,

I am in need of clarification. Everything I've seen from the effects of the 
Hiroshima and Nagasaki detonations suggest that the initial burst of rad during 
the blast in the 3-km annulus around, but outside of, the blast zone caused the 
radiation-related cancers and deaths in the surviving cohort, and when I plot 
cancers, it is indeed linear with dose down to about 10 rem where it merges with 
background (Figure attached), but that fallout did nothing measurable. Is this 
correct? Is it because doses from fallout were so low?

Thank you,
