A whole body counting technique is described which allows monitoring of gamma ray emission rates from body levels of /sup 59/Fe and /sup 65/Zn in the same range as emission rates of gamma rays from naturally occurring /sup 40/K in the total body. Consequently absorption/retention studies were performed with doses of 0.1 microCi. Experimental results from studies using corn intrinsically labeled with /sup 65/Zn and wheat intrinsically labeled with /sup 59/Fe are presented and illustrate how absorption of /sup 59/Fe as low as 4% and retention of /sup 65/Zn up to 418 days were measured in humans.
