The School of Nuclear and Allied Sciences (SNAS), a graduate school, was
jointly established by the Ghana Atomic Energy Commission (GAEC) and the
University of Ghana (UG) in co-operation with the International Atomic
Energy Agency (IAEA), in 2006, with the purpose of training more nuclear
scientists and engineers to meet the manpower requirements for peaceful use
of nuclear energy in Ghana and the whole of Africa. The School was
designated as IAEA Regional Centre of Excellence for Professional and
Higher Education in Nuclear Science and Technology in September 2009.
Again, in October 2011, the School was endorsed as an IAEA Regional
Designated Centre for Training in Radiation Protection. Less than a decade of its existence, the School has developed and mounted
12 nuclear oriented academic programmes under 5 academic departments for
the award of M. Phil. and Ph.D. degrees of the University of Ghana and a 5
month IAEA post graduate Education Course (PGEC) in Radiation Protection.
The academic department and areas of specialization Department of Nuclear
Sciences and Applications (Applied Nuclear Physics, Nuclear Earth Science,
Nuclear and Radiochemistry, Nuclear and Environmental Protection);
Department of Nuclear Safety and Security (Radiation Protection, IAEA Post-
Graduate Education Course in Radiation Protection); Department of Nuclear
Engineering (Nuclear Engineering, Computational Nuclear Sciences and
Engineering, Nuclear Technology Applications in Petroleum and Mining
Industries); Department of Nuclear Agriculture and Radiation Processing
(Nuclear Agriculture, Radiation Processing), Department of Medical Physics
(Medical Physics, Nuclear Science and Technology). Over 270 M.Phil. students (both Ghanaian and foreign) and 10 Ph.D.
students have graduated from various programmes of the School and a total
of 60 students (including 54 international students) have successfully
completed the Post Graduate Educational Course in Radiation Protection.
Current students and alumni have come from Ghana, Angola, Benin, Botswana,
Burkina Faso, Cameroon, Chad, DR Congo, Egypt, Eretria, Ivory Coast,
Jamaica, Kenya, Malawi, Mozambique, Namibia, Nigeria, Seychelles, Sierra
Leone, Sudan, Tanzania, South Africa, Uganda and Zambia with many more
applying to be admitted from other African countries. The contribution to knowledge in the nuclear and related sector is evident
through the numerous theses, technical documents and papers in peer
reviewed journals. In this publication, you will find the abstracts of research projects
conducted by past students of the School from 2006 to 2013. We hope that
this compilation will serve as a reference point for students, researchers
and lecturers all over the world. We are very grateful to the compilers for
painstakingly bringing together the abstracts and we look forward to
regular updates. Yaw Serfor-Armah, PhD, FGA

Dean, School of Nuclear and Allied Sciences,
University of Ghana-Atomic This publication contains abstracts of Masters and Doctorial theses of
students of the
Graduate School of Nuclear and Allied Sciences since 2008. The purpose is
to bring in one place and provide an overview of completed MPhil. and PhD
theses for the benefit of students, lecturers and researchers in nuclear
and related sciences. Prospective students and researchers will
particularly find it useful because it will enable them at a glance know
what has already been done in their fields of study and also assist them to
formulate their own research areas. Abstracts listed in this publication are original author abstracts. They
are arranged by academic departments, and within each department, they are
arranged by year of publication, followed by title and author. All theses
listed are currently available for reference at their respective
departments at the Graduate School of Nuclear and Allied Sciences.

0001 Atmospheric dispersion modeling and radiological safety analysis for
a hypothetical accident of Ghana Research Reactor - 1 (GHARR-1)
Lunguya, J. M. (M.Phil)
This work presents the environmental impact analysis of some selected
radionuclides released from the Ghana Research Reactor- 1 (GHARR-1)
after a hypothetical postulated accidents scenario. The source term
was identified and generated from an inventory of radioisotopes
released during the accident. Atmospheric transport model was then
applied to calculate the total effective dose and how it would be
distributed to different organs of the human body as a function of
distance downwind. All accident scenarios were selected from GHARR-1
Safety Analysis Report. After the source term was identified the MCNPX
code was used to perform the core burnup/depletion analysis. The
assumption was made that the activities were released to the
atmosphere under a horse design basis accident scenario. The gaussian
dose calculation method was applied, coded in Hotspot, a Healthy
Physics computer code. This served as the computational tool to
perform the atmospheric dispersion modeling and was used to calculate
radionuclide concentration at downwind location. Based upon
predominant meteorological conditions at the site, the adopted
strategy was to use site-specific meteorological data and dispersion
modeling to analyze the hypothetical release to the environment of
radionuclides and evaluate to what extent such a release may have
radiological effects on the public. Final data were processed and
presented as Total Effective Dose Equivalent as a function of time and
distance of deposition. The results indicate that all the values of
Effective dose obtained are far below the regulatory limits, making
the use of the reactor safe, even in the case of worst accident
scenario where all the fission products were released into the
atmosphere. 0002 Comparative studies on permanent prostate brachytherapy: pre-plan and
real-time transrectal ultrasound guided iodine-125 seed implants at
Korle-Bu Teaching Hospital, Ghana
Kalolo, L.T. (M.Phil)
This research was carried out to investigate and compare the real-time
and pre-plan implant at the Radiotherapy Department of the Korle Bu
Teaching Hospital, Ghana. Prowess Panther 4.5 treatment planning
system and variseed 7.2 software were used for pre-plan and real-time
implant respectively. The study was conducted for eighty three (83)
patients treated for prostate cancer through real-time implant
brachytherapy
