Preparation and characterization of working standards for 238Pu

摘要

An attempt is made to prepare and characterize the working standards of 238Pu by mixing solutions of enriched isotopes of 2'8Pu and 23<)Pu, available indigenously. The working standards were characterized using the recently developed interfering element correction methodology in thermal ionization mass spectrometry (TIMS) and the data were compared with those obtained by conventionally used alpha spectrometry.
