696. Rapid Method for the Determination of Actinides and 93Zr in Radioactive Waste, Biological and Environmental Samples

Prof. Nóra Vajda (RADANAL Ltd.)

Nuclear Analytical Methods

Invited

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)....

553. Rapid Determinations of Sr-90, Am-241 and Plutoniumisotopes in Emergency Exercises

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...

595. Determination of Mo-93 (and Nb-94) in nuclear decommissioning waste from a nuclear reactor

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,...

520. The AUTORAD platform for the automated radiochemical analysis

Dr Vicente Vilas Víctor (European Commission, Joint Research Centre, Directorate for Nuclear Safety and Security, D-76125 Karlsruhe/Germany)

Nuclear Analytical Methods

Verbal

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....

434. TRLIF and TRLIC Laser Spectroscopy and Detection of Actinides/Lanthanides in Solutions

Prof. Igor Izosimov (JINR)

Nuclear Analytical Methods

Verbal

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...
