Microdosimetric modelling of radiation-induced luminescence

Dr. Alessio Parisi

Belgian Nuclear Research Centre SCK•CEN, Belgium


2015  Master of Science in Nuclear Engineering, University of Pisa (Italy)

2018  PhD in Engineering, University of Mons and Belgian Nuclear Research Centre SCK•CEN (Belgium)

This talk deals with the development and validation of the Microdosimetric d(z) Model able to describe and predict the efficiency of luminescent detectors for measuring different radiation qualities. Firstly, the theoretical background, the assumptions behind the model and its methodology are reviewed in detail. Afterwards, the results of the model are benchmarked through a comparison with experimentally determined efficiency values. In addition, a systematic investigation on the effect of simulation parameters on the calculated efficiency values is included in the discussion. Finally, some immediate applications of the model are shortly presented.

Radiation sources are used for research, medical and a myriad other applications across Africa.  Although policies have been formulated at national or institutional level to safeguard against deleterious effects of exposure to radiation, new emerging threats such as nuclear terrorism have called attention to the need for training in international best practice in this area.  In this talk, we will look at contemporary efforts to strengthen regulations for nuclear security against threats from misuse of nuclear and radioactive material in Africa.

Dose reconstruction using surrogate dosimetry materials

Prof. Ian Bailiff

University of Durham, UK


1986 Science and Engineering Research Council Advanced Fellow

1991 Lecturer, University of Durham

2003 Professor, University of Durham


Luminescent minerals extracted from ceramic tiles taken from buildings in Hiroshima were first used in the 1960s to measure absorbed gamma dose due to the atomic bomb detonation. The approach was progressively developed to provide a tool, now referred to as retrospective dosimetry, to support dose reconstruction studies where historically widespread dispersal of radioactive contamination had occurred in populated areas. More recently, attention has focused on developing techniques that are applied promptly to support medical triage for individuals exposed in the event of a radiological emergency (e.g., a malicious attack). Suitable surrogate materials located close to the body are preferable, such as personal possessions, and the alumina substrates of surface-mount components in mobile phones have attracted the most attention. However, the progressive reduction in their physical size arising from advances in device technology has prompted the search for alternatives and this paper examines the suitability of the characteristics of various materials for the role of individual dose estimation in these circumstances.

Challenges and opportunities in radiation therapy dosimetry

Prof. Gabriel Sawakuchi

Radiation therapy (RT) delivery technologies have dramatically evolved in the past decade. New techniques such as stereotactic body RT (SBRT), intensity modulated proton and C-ion therapy (IMPT) and magnetic resonance image guided RT (MRgRT) enabled delivering high doses to the tumor with unprecedented accuracy in geographical tumor targeting. However, due to their small and complex radiation fields, these new techniques imposed unique challenges to radiation detectors. This presentation will review the challenges and opportunities of RT dosimetry with emphasis on how solid state detectors could have a positive impact on helping to answer basic questions of RT radiobiology.

A review on the OSL of BeO in light of recent discoveries - the missing piece of the puzzle?

Dr. Eduardo Yukihara

Paul Scherrer Institut, Switzerland


2004  Assistant Professor, Physics Department, Oklahoma State University

2009  Associate Professor, Physics Department, Oklahoma State University

2016  Head of the Dosimetry Group, Department of Radiation Safety and Security, Paul Scherrer Institute

2016-2018  Professor, Physics Department, Oklahoma State University

2018  Head of the Radiation Metrology Section, Department of Radiation Safety and Security, Paul Scherrer Institute


The mechanism responsible for the optically stimulated luminescence (OSL) of dosimetric BeO has been puzzling because of contradictory results on the correlation between the OSL and the thermoluminescence (TL) in this material. The recent discovery of intense thermally transferred OSL (TT-OSL) in BeO, however, provides a new piece for this puzzle. In this talk we will review the results on the TL and OSL BeO that are important to formulate a model in this material, present the new data on the TT-OSL in BeO, and discuss how this phenomenon may help elucidate the OSL mechanism in BeO.
