Full Time
Organization Type

At the CERAD Centre of Environmental Radioactivity (Centre of Excellence), Faculty of Environmental Sciences and natural resources (MINA)/Section for Environmental chemistry, there is a 1 year position (with possible extension) open for a research scientist within environmental radioactivity/radioecology with focus upon radionuclide speciation, in geological (particles) or biological materials using advanced techniques.

The position is funded by CERAD CoE

The Faculty of Environmental Sciences and Natural Resource Management (MINA) has about 180 employees and undertakes teaching, research and dissemination within the fields of geology, soil science, environmental chemistry, forestry, biology and ecology, natural resource management, renewable energy, nature based tourism. The faculty has ca. 600 students, and approximately 90 PhD-students. The employees of the faculty are significant participants in their respective fields of expertise, both nationally and internationally and have a high level of scientific production. For more information:

In 2013 the CERAD Center of excellence was established at MINA/Isotope Laboratory in collaboration with NRPA, MET, NIVA and NIPH. CERAD focuses on new scientific knowledge and tools for better protection of people and the environment from harmful effects of radiation. For more information see

Research project

The project will be an integrated part of CERAD and the work will be performed in close collaboration with other projects on the characterization of radionuclide/trace element species in different sample matrices (water, soils, biological samples), utilizing advanced equipment at NMBU or internationally, thus offering an interdisciplinary and stimulating scientific environment to the researcher. The CERAD consortium provides expertise on different methodologies and instruments associated with radionuclide/metal speciation. The research work will also be performed in collaboration with international partners offering access to international platforms.

Following severe nuclear events (nuclear weapon tests, nuclear accidents) a major fraction of radionuclides released to the environment was present as radioactive particles. Such entities may carry substantial radioactivity and represent point sources of radiological concern. Focus is therefore to link particle characteristics and radionuclide speciation to sources, and to link particle characteristics to ecosystem transfer (e.g., weathering rates), utilizing advanced technologies. Part of the work will be linked to the particle archive available at NMBU.

Main tasks

The main tasks of the PostDoc position are to:

  • Characterize radioactive particles with respect to composition, particle size distribution, structure and oxidation state of the carrying matrices, using 2D and 3D techniques

  • Link the particle characteristics to specific sources

  • Link particle characteristics to weathering rates utilizing defined extracting agents

  • Utilize separation techniques for quantifying exotic radionuclides such as transuranics.

The work will be carried out as part of a team of researchers, doctoral fellows and graduate students at the Centre of Environmental Radioactivity, The Faculty of Environmental Sciences and Natural Resource Management, and together with international partners.
