Bunzl, W. Kracke] A radiochemical procedure is given for the simultaneous determination of low levels of129I, actinides (Pu, Am, Cm) and90Sr in vegetation samples. It is shown that grass samples up to 5 kg fresh weight can be wet ashed conveniently by hydrogen peroxide under alkaline conditions, subsequent to an initial enzymatic disintegration. After purification of the iodine fraction,129I is determined by neutron activation analysis. Using alpha spectrometry,238Pu and239,240Pu are determined in the plutonium fraction, and241Am,242Cm, and244Cm in the americium/curium fraction. The90Sr is determined after separation by beta counting its decay product90Y. Akadémiai Kiadó, 1992 Bunzl K.
