The distribution of an abundant short-lived (285 days) nuclide, cerium-144, and a long-lived (30.5 years) nuclide, cesium-137, has been measured in wheat samples and milling products by means of radiochemical methods. The patent flour fraction contained approximately 10 and 15 percent of the measured cerium and cesium.
