Richard Klos

Key Associate

Dr. Richard A. Kłos has degrees in Physics from Imperial College, London (BSc) and X-ray Astronomy from Leicester University (PhD). He has worked for the UK’s National Radiological Protection Board, the Paul Scherrer Institute (in Switzerland), as an independent consultant, and as an employee of GSL. He has over fifteen years experience in a range of issues concerning the assessment of the performance of facilities for radioactive waste disposal and management.

Dr. Kłos’ work ranges form the detailed definition, implementation and analysis of environmental transport and dose assessment models for radionuclides (and other contaminants), to the detailed application of probabilistic analysis techniques in uncertainty and sensitivity analyses. He has worked extensively in the field of the biosphere component of performance assessment, and has carried out numerical analyses of the potential for sorption dynamics to influence the transport of radionuclides on colloids.

Dr. Kłos has been involved in projects on behalf of EPRI (US), BNFL (UK), Nirex, (UK), SSI (Sweden), NAGRA (Switzerland), and ANDRA (France). In particular, Dr. Kłos was responsible for the development of biosphere and dose assessment models in the Swiss national waste disposal programme on behalf of NAGRA.

Dr. Kłos has participated actively in a range of international biosphere modelling projects. He chaired the IAEA’s BIOMOVS II complementary Studies Working Group – a study which tested and compared a wide variety of assessment models for biosphere transport and dose assessment. The practical implementation of the BIOMASS approach to the characterisation of Candidate Critical Groups for long-term assessments was a major part of his involvement in BIOMASS. He was the leader of the NEA’s PSACOIN Level 1b project, which investigated the role of probabilistic uncertainty calculations in the biosphere.
