Mrs Tina Eboka
Mrs Tina Eboka, NTP GMD (left) elected to serve as Vice-President of the HLG-MR. She is seated next to the President of the HLG-MR and the Secretariat.
Congratulations NTP's Group MD, Tina Eboka on her election as the Vice Chairperson of the High-level Group on the security of supply of Medical Radioisotopes (HLG-MR)!
This is truly a momentous occasion for NTP and South Africa!
In 2009/10 the world experienced a global shortage of Molybdenum (Mo-99) and Technetium (Tc-99), both essential medical radioisotopes. Therefore the HLG-MR was established by the Nuclear Energy Agency (NEA) with the main objective being to identify the causes of the supply shortage, while compiling a policy approach to ensure long term security of supply.
Forty experts represent the governments of Argentina, Australia, Belgium, Brazil, Canada, Czech Republic, France, Germany, Japan, Republic of Korea, the Netherlands, Poland, the Russian Federation, South Africa, Spain, the United Kingdom and the United States, as well as from the European Commission (Euratom Supply Agency) and the International Atomic Energy Agency (IAEA).
The Necsa Group is proud, South Africa is proud!
“This is a great honour for South Africa and a wonderful opportunity for NTP to demonstrate global leadership in this crucial arena!" - Piet Louw (Executive Manager, Global Isotopes)
Tina, we heard you say: “It may be very, very lonely sometimes being a leader.” But Team NTP assures you that you are not alone on this journey!
You also said, "So every day the landscape changes – at NTP, in our country and in our world. But let me tell you what gets me up in the morning…the vision I have to be a part of the team at NTP – who can change the world: One Curie of Moly at a time. One patient treatment at a time. One happy employee at a time. One more Rand, Dollar or Euro at a time."
So from the Necsa Group- Thank you for playing your part in changing our world for the better!
Congratulations to Maurice Mashau
We would like to congratulate Mr Maurice Mashau from the Radiation and Reactor Theory (RRT) Section of R&D/RS on obtaining his Master’s Degree in Energy studies with distinction on 14 June 2016.
His supervisor at UJ was Prof SH Connell and his co-supervisors at RRT were Dr RH Prinsloo and Mr B Erasmus.
His dissertation was entitled: “Simulation of a Selected Subset of The Recently Published IAEA Reactor Experimental Benchmark Set in Aid of Verification and Validation of the OSCAR-4 System.”
We are proud of you Maurice!
Congratulations to Linina Jurbandam
We would like to congratulate Ms Linina Jurbandam, a SANHARP student from the Radiation and Reactor Theory (RRT) Section of R&D/RS on winning the first prize for the best oral Honours presentation in the Nuclear, Particle and Radiation Physics Specialist Group at the South African Institute of Physics Annual Conference. Dr Oscar Zamonsky is her supervisor at Necsa needs to be mentioned as he is supporting her in all her endeavours.
It was an amazing achievement as it was in the context of a well subscribed set of sessions with many excellent contributions of a very high standard. Linina's presentation was entitled "Evaluation of Fission Energy Deposition in the SAFARI-1 Nuclear Reactor".
Congratulations to Rendani Madzia!
Radiation Protection Training Centre (RPTC) is proud to announce that Rendani Madzia. Née: Ramabulane has done it again! She obtained her Masters degree with distinction and graduated on 14 June 2016 at the University of Johannesburg. Her supervisors Dr. RD Mavunda of RPTC (Necsa) and Dr TB Madala of the University of Johannesburg are delighted with her achievement.
Another excellent performance by a Necsa team!
We are proud to announce that the Diffraction Group of the Radiation Science Department of the R&D Division made it to the finals of the NSTF awards in the category “Research leading to Innovation by a Corporate Organisation”. As such the team members will already receive certificates of merit even though the over-all winning team still has to be announced at a prestigious function on 30 June 2016.
The team was nominated for the development of two world-class neutron diffraction instruments, MPISI and PITSI, at the SAFARI-1 research reactor. SAFARI-1 is a national asset with an impeccable safety and operational record. The development of world-class neutron instruments for niche applications is important to expand its institutional value even further. The resulting suite of non-destructive experimental techniques offered by the two new instruments benefits many materials related research fields. This is made possible because neutrons probe deep into materials to reveal information about atomic and magnetic properties at the micro-structural level, providing a powerful diagnostic for researchers in fields such as advanced manufacturing, metallurgy, nuclear materials and mineral beneficiation, all disciplines at the root of a knowledge economy.
The team of multi-disciplinary subject experts was led by Dr Venter, an expert in neutron diffraction science. The respective roles played were:
- AM Venter: Scientific group leader.
- PR van Heerden: Development and integration of mechanical subsystems.
- JC Raaths: Integration of electronic and neutron detector systems.
- D Marais: Customisation of software control system and development of data acquisition and treatment modalities.
- M Hayes, TP Ntsoane and ZN Sentsho: Scientific commission, testing and validation

Congratulations to Rendani Madzhie
Rendani Madzhie a Masters students in Biochemistry at the University of Johannesburg whose paper was accepted and published by ELSEVIER: Science Direct.
She is co-supervised by Dr RD Mavunda of Radiation Protection Training Centre (RPTC), Necsa.
Oxidative stress is a condition in which the balance between the production and elimination of reactive oxygen species (ROS) is disturbed. However, plants have developed a very sophisticated mechanism to mitigate the effect of ROS by constantly adjusting the concentration thereof to acceptable levels. Electromagnetic radiation is one of the factors which results in oxidative stress. In the current study, ionizing gamma radiation generated from a Cobalt-60 source was used to induce oxidative stress in Phaseolus vulgaris seedlings. Plants were irradiated with several radiation doses, with 2 kGy found to be the optimal, non-lethal dose. Metabolite distribution patterns from irradiated and non-irradiated plants were analyzed using UHPLC-qTOF-MS and multivariate data models such as principal component analysis (PCA) and orthogonal projection to latent structures discriminate analysis (OPLS-DA). Metabolites such as hydroxycinnamic phenolic acids, flavonoids, terpenes, and a novel chalcone were found to be perturbed in P. vulgaris seedlings treated with the aforementioned conditions. The results suggest that there is a compensatory link between constitutive protectants and inducible responses to injury as well as defense against oxidative stress induced by ionizing radiation. The current study is also the first to illustrate the power of a metabolomics approach to decipher the effect of gamma radiation on crop plants.

Congratulations to Linina Jurbandam
We would like to congratulate Ms Linina Jurbandam, a SANHARP student from the Radiation and Reactor Theory (RRT) Section of R&D/RS on obtaining her BSc Hons in Physics at the WITS University.
Dr Iyabo Usman was her study leader for WITS and Dr Oscar Zamonsky was her study leader at Necsa. She is continuing her studies towards her MSc in Nuclear Engineering at RRT under the supervision of Dr Oscar Zamonsky.

Congratulations to Dr Mpho Lekgoathi
We would like to congratulate Dr. Mpho Lekgoathi, a senior scientist in the Delta F section of Applied Chemistry (R&D Division), on obtaining his PhD degree in Chemical Technology at the University of Pretoria. His thesis was titled “High purity LiPF6: Its physical properties and the synthesis of PF5 gas as precursor for LiPF6 production”, prepared under supervision of Prof. P.L. Crouse of UP, with Dr. L.D. Kock of Necsa R&D as co-supervisor.
In this thesis an improvement to the process of synthesising lithium hexafluorophosphate for applications in lithium-ion batteries is proposed. The new process is the result of an ancillary, but relevant, investigation into the preparation of pure phosphorus pentafluoride gas, supported by an experimental and theoretically calculated infrared and Raman vibrational analysis. The new process has laid a foundation for future research into the production of electrolytes for lithium-ion batteries and is being patented.
This work also led to the publication of four papers in peer reviewed journals. In addition, Dr. Lekgoathi received a Merit Certificate for Academic Colours from the UP Student Representative Council.
We congratulate Mpho on these excellent achievements!
