This report summarizes accomplishments for the second phase of a 5-year program designed to develop a portable monitor for sensitive hazardous waste detection. The approach is to excite atomic fluorescence by the technique of Spark-Induced Breakdown Spectroscopy (SIBS). The principal goals for this second phase of the program were to demonstrate sensitive detection of additional species, both RCRA metals (Sb, Be, Cd, Cr, Pb, As, Hg) and radionuclides (U, Th, Tc,3603 ); to identify potential applications and develop instrument component processes, including, sample collection and excitation, measurement and test procedures, and calibration procedures; and to design a prototype instrument. Successful completion of these task results in being able to fabricate and field test a prototype of the instrument during the program`s third phase.
