ABSTRACT
The subject of strontium-90 in our food supply, and particularly in milk, is of considerable interest to the dairy industry and to others concerned with public health.
Our primary concern is to know the degree to which milk may be contaminated with radioactivity. But there is another interest of equal importance—that of being informed—so that we may stabilize public thinking with accurate information, to refute irresponsible "scare" stories which could affect milk consumption and national health.
With this is mind, an effort has been made to ascertain, reliably, the facts as they are presently known concerning strontium-90 in milk.
It is accepted that high doses of radiation from strontium-90 can produce harmful effects in human beings and that increased amounts of strontium-90 have been detected in our milk supply. The latter has probably occurred as a result of nuclear fall-out which reaches our soil and enters plant life, which is later consumed by animals and turns up in their milk.
