DIET has also been applied to the study of rare earth oxides, YBaCuO oxides as well as Si02 with significant contribution to the understanding of their structure. Loubriel, Knotek, Stulen, Koel and Parks studied the ESD and PSD of oxide films of Ce and Er and compared the results with those obtained by Soft X-ray absorption, SXA [135]. From the ESD experiments they concluded that the 5p level in the rare earth is involved in the electronic transitions for ion desorption from the surface. Schmidt-May, Sent, Voss, Kunz, Flodstrom, Nyholm and Stockbauer later studied the resonant electron and ion emission and the desorption mechanism from oxides of Sm, Eu and Yb [136]. They observed that the enhancement in photoelectron at the 4d edge is also found in the ion desorption yield. They concluded that the use of PSD as a proof of the specific desorption site is strongly limited because the initial excitation does not occur in the surface complex from which the detected ion is being desorbed.

Recendy Kaplan and Park studied chemically crosslinked dextran hydrogels for application in the controlled deliveiy of bioactive proteins (Kaplan and Park, 1995). Dextran was functionalized by reacting it with glycidyl acrylate to introduce reactive double bonds. Upon exposure to y-irradiation the functionalized dextran formed a crosslinked gel which could be degraded by dextranase.

Optical counters have been widely used to monitor cleanroom technology and particles in oil. Instmments manufactured by Royco Inc. (Menlo Park, California) are available for studying aerosols and particles in Hquids. The HIAC counter (HIAC Instmments, Monte Claire, California) is a widely used stream counter for particles in fluid. One of the more recently developed optical counters is available from Particle Sizing Systems (Santa Barbara, California). The configuration of one of the widely used counters, the Climet counter, is shown in Figure 16. A general review of photozone counters is available (3).

These figures can be used for predictive purposes to extrapolate average major incident conditions to situations under study, provided the actual conditions under study correspond reasonably well with average major incident conditions. Such a condition may be broadly described as a spill of some tens of tons of a hydrocarbon in an environment with local concentrations of obstructions and/or partial confinement, for example, the site of an average refinery or chemical plant with dense process equipment or the site of a railroad marshaling yard with a large number of closely parked rail cars. It must be emphasized that the TNT equivalencies listed above should not be used in situations in which average major incident conditions do not apply.
