"Investigation of Trace Uranium in Biological Matrices,"
INMM 54th Annual Meeting, 14-18 July 2013, Palm Desert, California, USA.
With the use of nuclear technology spreading, there is a growing
need to monitor workers for occupational exposures to ensure their
heath and safety. Methods for monitoring Uranium exposures have
been implemented for the entire lifetime of the nuclear industry;
however, using recent technologies, these methods can be improved.
This work is an implementation of an electrochemical
preconcentration process originally posited and developed at Oak
Ridge National Laboratory for use as a preprocessing to increase
both efficiency and sensitivity in conjunction with Inductively
Coupled Plasma Mass Spectrometry. The specific application of this
work is for detection of Uranium in urine for individuals exposed
during normal industry exposures as well as background exposures.
This work will discuss the feasibility of using this method for
preparing samples for analysis as well as the initial methodology
developments and observations from adaptation of the technique for
use with urine samples. Initial computer modeling suggests that
this technique will be effective for detecting chronic exposures of
Uranium; however, it will not be as effective in detecting short
term acute exposures. LA-UR: 'LA-UR-12-21937' Related LA-UR's:
