Abstract
In the present paper, the determination of Cs, Rb and Ba in biological materials, including human bones, eggs, milk, meat and vegetables by neutron activation analysis is described. The proposed technique is based on the measurement of the long-lived radioisotopes131Ba,134Cs and86Rb with a Ge(Li) detector, after a simple radiochemical separation based on selective retention of these nuclides on HAP in 6M HF. Detection limits of 0.001 ppm can be achieved with 5% precision. Data are given for replicate determinations in six different types of materials.
