Simple Screening Method for Gross Alpha Activities of Pu and Am by Extraction Chromatography.

Analysis of gross alpha, gross beta activities and beryllium- 7 concentrations in surface air: their variation and statistical prediction model

Background: Measurement of gross , gross activities, and cosmogenic beryllium-7 (7Be) concentrations were made both daily and weekly during the years 2001- 2004 from samples of atmospheric aerosols filtered from the air at Tehran Nuclear Research Center (35 41' N) and Zahedan (28 29' N). Materials and Methods: Weekly aerosol samples were collected with the high-volume air samplers on cellul...

Screening Method for Mononitrotoluenes in Natural Waters Using Magnetic Solvent Bar Liquid-Phase Micro-extraction Followed by Gas Chromatography-Flame Ionization Detection

A simple andefficient hollow fiber-based method,viz magnetic solvent bar liquid-phasemicroextraction (MSB-LPME) combined with gas chromatography-flame ionization detection (GCFID)has been successfully developed for the trace determination of mononitrotoluenes (MNTs) innatural water samples. The analytes were extracted from sample solution to the organic solventimmobilize...

Electronic structure of Pu and Am metals by self-consistent relativistic GW method

We present the results of calculations for Pu and Am performed using an implementation of a self-consistent fully relativistic GW method. The key feature of our scheme is to evaluate polarizability and self-energy in real space and Matsubara’s time. We compare our GW results with the calculations using local density and quasiparticle approximations and also with scalar-relativistic calculations...
