Nature 178, 85-5 (1956).
Samples of powdered milk and beef preserved during
the years 1953 to 1956 were examined for the presence
of y-radiation. The higher yeradiation found in the
last year was attributed to an increase in fission
products.
Data are compared with measurements on a
series of children.
