Key Research Areas:
- Development of automated methods for the determination
of radionuclides. Some automated separation methods have
been developed by employing flow injection/sequential injection
techniques and chromatographic separation techniques for rapid and
automated separation of radionuclides from matrix and interfering
elements and radionuclides, the established method can
significantly shorten the analytical time from a few days to less
than 2 hours, as well as improve the analytical capacity by
automated operating the separation over night. This initiation
meets the requirement for analysis of large number of environmental
and waste samples in a short time.
- Marine chemistry of iodine. Study of marine
chemistry of iodine, marine geochemical cycle of
iodine,Utilization of reprocessing 129I as an
oceanographic tracer to study transport of water masses in the
Nordic Seas; Application of speciation analysis of 129I
as an oceanographic tracer to investigation of marine geochemical
cycle of stable iodine.
- Characterisation of nuclear waste for decommissioning
by radiochemical analysis. Quick determination of tritium
and C-14 in graphite and concrete from nuclear facilities;
Simultaneous determination of Ni-63, Fe-55, Ca-41, Sr-90 in
concrete from nuclear facilities; Determination of Cl-36 and I-129
in concrete, graphite, steel, aluminium, lead, and water samples.
Estimation of radioactivity inventory in the nuclear facilities.
Collaboration with Danish Decommission, and Barsebäck
NPP.
- Nuclear fuel cycle. Study of the reprocessing
procedure, dissolution of the spent nuclear U(Pu)O2 fuel elements,
adjustment of valence of plutonium in PUREX process. Chemical
process of Th based fuel.
- Radioecology of 129I. Radiochemical
neutron activation analysis and acceperator mass spectrometry
analysis of 129I. Chemical speciation analysis of
129I in seawater, soil and sediment, Application of
129I for reconstruction of radiation dose of short lived
radioiodine in the Chernobyl region.
- Marine radioecology. Analysis of
radionuclides in the marine system, seawater, sediment, seaweeds
and marine biota for the investigation of the transport of
radioactivity in the ocean, application of radionuclides as
oceanography tracer.Collection and analysis of environmental data
from European water for estimation of radiation dose to European
people.
- Chemical speciation of radionuclides in
environment. Development of method for the chemical
speciation analysis of Pu, Np, Am, Tc, Re and iodine in marine and
terrestrial environmental samples, such as seawater, seaweed, fish,
soil, sediment, plants, and animal tissues. Investigation of
chemical speciation of above radionuclides in specific environment.
Project supported by Kan Villium Rasmussen Foundation (2005-2008),
NKS-B project (2007-2008)
- Chemical speciation of iodine in environmental and
biological system. ICP-MS and Epithermal neutron
activation analysis of ultra-trace iodine in biological and
environmental samples; Chemical speciation of iodine in seaweed,
human tissue and water; dietary uptake of iodine in China;
biological toxicity of different chemical species of iodine.
- Radiolabelling of proteins for protein adsorption
investigation. Labelling of proteins, polyphenol and humic
substance with 125I, 131I, and
99mTc; quantitative determination of protein
adsorption on surface for the study on surface modification of
polymeric biomaterials for improving biocompatibility using, plasma
polymerisation, chemical vapour deposition, graft polymerisation,
wet chemical grafting of natural and synthetic polymers. Project
supported by Danish Research Council (2008-2010)
- Analysis method for artificial and natural
radionuclides and their application in environmental
radioactivity: Development of liquid scintillation
counting method for beta radionuclide measurement; a Novel method
for the determination of Sr-90; Determination of Ra-226, 228 in
biological samples by liquid scintillation counting.
- Neutron activation analysis and it
application. Epithermal neutron activation analysis for
improvement of determination of some trace elements in biological
and geological samples. Study on the relationship of trace elements
with some diseases, such as respiratory system disease, senile
cataract and cancer; determination of the neutron spectrum in a
nuclear reactor.
