Research Profile Summary

My experience in the field of radiation detection and measurements started during the study of a master degree (1997-1998) at Surrey University, UK. My initial research interest was in the field of environmental radiation measurements. I undertook two main projects, the first one was to investigate the levels of radioactivity in sediment samples as a result of the discharge of low-level liquid radioactive waste from the nuclear fuel reprocessing plant into the sea in northern Britain. In the second project, I utilised a method of elemental analysis (non-distractive technique) to provide information on various heavy metal concentrations in a simulated industrial waste pipe.

In 1999, I joined the Radiation Biophysics Group at the University of Birmingham as a PhD. Student. My research work was in the field of radiation dosimetry. Much of my PhD work focused on the issue of hazards posed by radioactive fuel fragments in the environs of Dounreay, Scotland, UK. In this work, I was deeply involved in the developing and validating of several imaging techniques used for determining dose distributions around discrete radioactive particles (beta and gamma emitters). I worked closely with colleagues from the Research Institute at Churchill Hospital in Oxford, the University of Oxford, Birmingham University Hospital and the National Radiological Protection Board-NRPB.

I joined the Physics Department at Taif University in 2003. My work on measuring the levels of radioactivity in the foodstuffs, building materials and the environment is supported by Taif University. I have also collaborated on independent research projects with various faculty members from within the Physics Department at Taif University as well as scientists from the United Kingdom and Canada.

In March 2009, I joined the Faculty of Energy Systems and Nuclear Science, University of Ontario Institute of Technology as a Visiting Professor. I had been involved in a number of research projects, teaching and students’ supervision. My research interests focused on the following

Development and evaluation of different radiation detection and dosimetry systems. Specifically, the development of plastic scintillators for beta spectroscopy purposes and dosimetry.

Investigation of low energy fast neutrons using GafChromic dye films and tissue equivalent proportional counter.

Experimental and theoretical microdosimetric methods for improvement of radiation monitoring and the assessment of risk in nuclear power industry. In particular, study the microdosimetry of low energy beta and gamma radiation from tritium and long-lived fission products such as ⁹⁹Tc and ¹²⁹I.

All the research works were conducted at the UOIT research facilities and McMaster accelerator Lab at University of McMaster.

In Jan. 2019 I joined the Physics Department, Faculty of Science at King Abdulaziz Univerity. I am now more involved in teaching and suervizing post grad students.

I am also interested in developing virtual nuclear and radiation laboratory for education and training purposes. The major goal of the Virtual Lab Project is to increase scientific literacy by using interactive multimedia to educate the fundamental concepts of nuclear and radiation physics.

The outcomes of my collaborative research works have been published in reputable international journals. I have also attended several conferences in which I presented aspects of my research work in the form of posters or oral presentations.
