Fig. 7—Geographic location of markets included in the monthly milkconsumption network,
The range of values given for “Sr intake from milk are based on
average consumption data for the total population in each area.
Thus
they do not indicate the variations arising from age or other variables
that may influence the relative rate of consumption. Variations in
milk consumption by age can be obtained from the Public Health
Service— Bureau of the Census study’? conducted during July 1962 (see
Table 3). The range in values, which is from three- to fourfold, il-
lustrates another consideration in the estimating of dietary "Sr intake.
Since most milk is consumed by children and since this is the group of
the population considered most susceptible to Sr deposition, the age
factor must be critically examined.”
