    We all recognize that socioeconomic factors are influential in 
epidemiology. In the A-bomb attacks on Japan in 1945, the radiation 
exposures are estimated by distance from the epicenter of the explosion. 
In cities I am familiar with, the socioeconomics are quite different for 
different areas of a city.
    Combining this info, there may have been a strong correlation 
between radiation dose and socioeconomics. For example, if the epicenter 
was  above a poor section of the city and rich people lived in distant 
suburbs, poor people would have had higher radiation doses than rich 
people. Is this taken into account in determining dose-response 
relationships from the A-bomb survivor data?  If so, where is this 
explained? If not, why not?
