The use of reactor epithermal neutrons in instrumental activation analysis is described for the determination of trace elements via long-lived isotopes. A boron carbide filter is used. Results of analyses of human erythrocytes, plasma, urine and some biological reference materials are given to demonstrate the applicability of the method to biological samples. Bromine, iron, cesium, rubidium, selenium and zinc and cobalt are determined. The method provides accuracy and reliability similar to conventional thermal neutron activation but is faster. Limits of detection attainable with the two techniques are compared.

Neutron activation analysis was used to determine platinum in the tissues of rats that had received doses of the tumor chemotherapy agent cis-Pt. Two elements causing spectral interference were identified as 47Sc from 46Ca, a natural component of tissue, and tin (117mSn), an element introduced inadv
