Radiation Chemistry

Invited

Materials consisting of nanometer-sized particles have drawn substantial attention in wide range of research fields, mostly for their various unique properties originating from their small size or related high specific surface area. For this reason, the nanoscale materials have been considered for many applications (e.g. as phosphors, catalysts or sorbents). This talk covers brief history and...

314. Application of rare earth doped phosphate glasses in radiation dosimetry

Dr Piotr Szajerski (Institute of Applied Radiation Chemistry, Lodz University of Technology, Wroblewskiego 15, 93-590 Lodz, Poland)

Radiation Chemistry

Verbal

Presently ionizing radiation and radioactive isotopes are used in many fields of life, technology and medicine. Radiation and nuclear technologies are used for food and materials sterilization, radiation induced polymerization, materials modification, medical diagnostics and cancer therapies. In order to assure safe application of these technologies and to control radiation exposure to humans...

420. Application of ab-initio molecular electronic structure calculations of radiolytic and hydrolytic stabilities of prospective extractants

Mr Tomas Koubsky (Czech Technical University in Prague, Faculty of Nuclear Sciences and Physical Engineering)

Radiation Chemistry

Verbal

Many proposed sustainable nuclear fuel cycles include coextraction of minor actinides together with lanthanides from the high level liquid waste. The extraction of minor actinides is of particular importance due to their responsibility for the long-term radiotoxicity of the waste. For the trivalent actinides and lanthanides ions extraction, the diglycolamide (DGA) family of organic extractants...

408. Effects of Dose Rate on the Response of a Fluorescence Chemical Dosimeter for Ultra-fast Pulse Radiolysis

Dr Martin Precek (Institute of Physics AS CR)

14/05/2014, 11:30

Radiation Chemistry

Verbal

Recent developments in the utilization of high-power femtosecond lasers for generation of X-ray and particle radiation sources as well as the on-going deployment of the first multi-keV X-ray free-electron laser facilities (such as are the LCLS, SACLA and the European XFEL) have opened an opportunity for application of these ultrashort pulsed radiation sources to study radiation chemistry with...

9. Biological Treatment of Radioactive Wastes before Cementation

Dr Алексей Сафонов (Фрумкин ИФХЭ РАН), Dr Ольга Горбунова (ФГУП "РАДОН")

14/05/2014, 11:45

Chemistry of Nuclear Fuel Cycle / 1st ASGARD International Workshop

Verbal

The possibility of the preliminary microbiological treatment of the oil- and nitrate containing liquid radioactive waste (LRW) before solidification in the cement matrix was studied. It was experimentally proved earlier that the oil- and nitrate-containing cement compounds during long-term storage are characterized with the microbiological degradation due to the reaction of biogenic organic...
