Popis:	On the basis of experience with three incidents in which large levels of fission products were present prior to the incidents, three fission product nuclides, Mo/sup 99/, Ce/sup 143/, and Zr/sup 97/ are recommended as monitors. A method is described for Zr/sup 97/ based on TTA extraction of zirconium activity followed by milking and counting of the Nb/sup 97/ daughter activity. Relative standard deviation is 1.1%. (P.C.H.)
