Indirect UV absorbance and on-line radioactivity detection were used simultaneously to monitor the analytes. The radioactivity detector consists of conical plastic scintillating material with the capillary passing through the center to provide a 4π detection geometry. The wide end of the cone is optically coupled to a photomultiplier tube. Transient isotachophoretic techniques were employed to stack large volumes of samples which had low specific activities. Radioactivity detection of &lt;sup&gt;152&lt;/sup&gt;Eu and &lt;sup&gt;137&lt;/sup&gt;Cs was achieved at the nanocurie level for 80−100 nL injections. The detector is approximately 80% efficient, enabling samples resident in the detector window for 0.1 min to be reliably assayed. The separation of &lt;sup&gt;137&lt;/sup&gt;Cs and &lt;sup&gt;137&lt;/sup&gt;mBa isotopes, which are in secular equilibrium, was modeled to demonstrate the effects of the rapid decay of &lt;sup&gt;137&lt;/sup&gt;mBa.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">15</style></issue><accession-num><style face="normal" font="default" size="100%">77</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;LBNL-40487 NOT IN FILE&lt;/p&gt;</style></notes><custom2><style face="normal" font="default" size="100%">LBNL-40487</style></custom2><section><style face="normal" font="default" size="100%">2988</style></section><label><style face="normal" font="default" size="100%">Laser</style></label></record></records></xml>
