A novel method based on the retention and sequential elution of all actinides on a single small DGA resin® column has been developed and published recently1. DGA resin® is an actinide selective extraction chromatographic material which contains N,N,N’,N’-tetraoctyldiglycol-amide sorbed onto Amberchrom CG-71 inert support (developed by Horwitz et al.2 , available from Triskem International)....
Introduction
An exercise for emergency situations was held in the Austrian Agency for Health and Food Safety in cooperation with the federal state Carinthia. The Exercise was funded by the Federal Ministry of Sustainability and Tourism. Therefore 21 soil samples, 19 ground vegetation samples and 6 sediment samples were collected. During former emergency exercises samples were only measured...
Molybdenum is an alloying component of structural materials used in nuclear reactors. The activation product of stable Mo-92 (14.65% abundance) is Mo-93, which has a long half-life ((4.0±0.8)×10^3 years); so it is an important contributor of nuclear power plant wastes (especially dismantling wastes). As it decays by electron capture; its proper detection is very difficult. X-ray spectrometry,...
Innovative analytical methods for the determination of radionuclides are essential to optimize and reduce costly and time consuming sampling, and simultaneously to reduce potential radiation exposure of the operating personal. The AUTORAD platform is an automated and portable system for the separation, pre-concentration and determination of key radionuclides using flow scintillation counting....
This work is devoted to applications of the time-resolved laser-induced luminescence (TRLIF) spectroscopy and time-resolved laser-induced chemiluminescence (TRLIC) spectroscopy for detection of lanthanides and actinides. Pu, Np, and some U compounds do not produce direct luminescence in solutions, but when excited by laser radiation, they can induce chemiluminescence [1-4] of chemiluminogen...
