Uptake of Strontium 90
lel
Milk
Since early 195), 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 only since England monitors her
own milk.
Samples from Japan are received sporadically; samples from
State College, Mississippi; St. Louis, Missouri; and Portland, Oregon
have not been received since 1956.
These latter data can be found in
HASL-l2, "Environmental Contamination from Weapon Tests".
