Uptake of Strontium 90
3.1 Milk
Since early 1951, HASL has monitored milk for strontium 90
activity.
Powdered milk from Perry, New York and liquid milk purchased
in New York City have been analyzed weekly.
In 1955, five additional
United States locations and Japan and England were included in the
program.
Samples have been received from England since April 1957
but now serve cross-checking purposes since England monitors her own
milk.
Samples from Japan are received sporadically; samples from
State College, Mississippi; St. Louis, Missouris and Portland, Oregon
have not been received since 1956.
These latter data can be found in
HASL-L2, “Environmental Contamination from Weapon Tests",
