Cæsium-137 in Toronto Milk during 1959

Abstract

MEASUREMENTS of the changing cæsium-137 content of milk have been carried out in many parts of the world, particularly in the United States1 and the United Kingdom2. The Los Alamos group measured the activity of Ontario milk during 19583. Here we present results of measurements on milk taken from the Toronto milk-shed during the period April 1959–February 1960.
