I am a radiochemist trained in developing/optimizing radioanalytical methods for radioactivity analyses quantifying radionuclide massic activities in different matrices.
I used and optimized over the years a range of radiochemical techniques for separation of radionuclides from a wide variety of matrices (from pure solution to complex environmental and biological samples). Those includes:
Within the Radioactivity Group's efforts in developing Standard Reference Materials (SRM) I am actively involved in International Laboratory Intercomparison projects to certify Natural Certified Reference Materials and to determine radioactive impurities in pure SRMs.
I am actively involved in two Proficiency Testing (PT) Programs: the Radiological Traceability Program (RTP) between the DOE Reference Laboratory, the Radiological and Environmental Sciences Laboratory (RESL); and NIST Radiochemistry Intercomparison Program (NRIP) by preparing and characterizing performance testing materials and conducting measurement traceability evaluations of participating radianalytical laboratories.
