✦ Synopsis

Very low levels of plutonium ("r*2'0P~ and "'Pu) in marine samples (sea water. sediments, marine organisms) are determined by extraction on columns of tri-n-octyl phosphine oxide supported on microporous polyethylene (Microthene-710). electrodeposition and ospectrometry. z'sPu or 24zPu is added as the yield detector and a highresolution a -_pectrometer is used for counting. The final recoveries are 62.6% ? 9.7(u) for sea water. 45.45% 5 9.6(o) for sediments and 61.7% _ * -I .5(o) for marine organisms. The method enables z'**140P~ and 3"Pu to be detected at the femtocurie level. 11 A. Aarkrog, Reference Methods of Marine Radioactivity Studies II. Tech. Rep. Ser.
