title: Determination of 90Sr in milk by using two inorganic exchangers.
abstract: Two inorganic exchangers, consisting of PRTD (partially reduced tin dioxide) and CUCR (normal copper chromate), both prepared and studied by the authors, were investigated for radiochemical isolation and purification of 90Sr from milk samples. A procedure combining the use of both exchangers is reported and is recommended when it is necessary to remove a radiobarium interference. Due to the lack of appropriate samples the procedure was tested using defatted milk spiked with 90Sr and 133Ba.
