Assessment of size-fractionated species of curium-244 via alpha spectrometry in groundwater Academic Article uri icon

abstract

  • Curium was produced for experimental programs for use as a heat source for isotopic electrical power generators and by 1968 approximately 5 kg had been produced at the Savannah River Site (SRS). Size fractionated groundwater samples were collected near a disposal basin in F-Area at SRS in 1998 and in 2004. Separation of (244)Cm via extraction chromatographic methods was followed by alpha spectrometric measurement. In both years a trend of increasing Cm activities downstream of the seepage site was observed. Migration and immobilization resulting from base injection remediation between sampling dates explain large differences in (244)Cm concentration.
