12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptAssessment of U and Th concentration in Granitic Rocks in EgyptUsing ray Spectroscopic Analysis with NTDsE. H. Ghanim1*, Kh. A. Shinashin2, A. Hussein3 and M. A. El Fiki4(1)Basic Sciences Department, Faculty of Industrial Education, Beni-Suef University, BeniSuef, Egypt(2)Physics Department, Faculty of Science, Port Said University, Port Said, Egypt(3)Physics Department, Faculty of Science, Menoufiya University, Shibeen El Koom, Egypt(4)Radiation Measurements Lab, Ionizing Radiation Department, National Institute forStandards (NIS), EgyptABSTRACTThe determination of both uranium and thorium contents in natural granite rocks wascarried out without the need of standard sources. A combined technique of nuclear trackdensity counting system and gamma spectroscopic analysis has proved to be an adequate andreliable technique for U and Th determination in natural crustal samples. Results of U and Thanalysis showed that in Gabal El-Massakat region, U content ranges from 78 to 588 ppm andTh content ranges from 15 to 130 ppm. In El-Eradyia area U content varies from 55 to 94 ppmand Th from 10 to 230 ppm. Also, measurements of radon gas emanating from the studiedsamples were also included using a specially constructed chamber. An overall estimation ofradon concentration using some of the studied samples show that Rn concentration in Gabal ElMassakat area ranges from 645 to 1088 pCi /1 while for the samples collected from Gabal El Majal area ranges from 4 to 27 pCi/1. Results are discussed within the frame work of track formationtheories and etching mechanism in nuclear track detectors and ray spectroscopic analysis.Corresponding Author e-mail address : (emadhamed 65@yahoo.com)11

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptMicroanalysis and Signature of Rare Earth Elements in Geochemical SamplesUsing Neutron Activation AnalysisM.F. Attallah1, Fatma S. Abdou2, H.F. Aly3(1)Analytical Chemistry and Control Department, Hot Laboratories Center, Atomic EnergyAuthority, Egypt(2)Egypt Second Research Reactor, Reactor Physics Department, Nuclear ResearchCenter, Atomic Energy Authority, Egypt(3)Chemistry of Nuclear Fuel Department, Hot Laboratories Center, Atomic Energy Authority,EgyptABSTRACTNuclear techniques are applied for exploration and efficient tapping of natural resources, byfinding promising resources of mining and mineral processing industries. A number of mineralsare existing in the Nuba Mountains. Fluorite occurs in various locations. Fluorites in the NubaMountains are classified into four categories based on their petrography. The rare earth elements(REEs) geochemistry in four fluorites samples, collected from Nuba Mountains are determinedusing neutron activation analysis technique. The REEs concentration ranges between 685 and1747 ppm. The Calcium is a major element in the four samples. The Fe, Al, Na, Ba and Sr arefound as minor elements in the investigated samples. In addition, tracer levels of U, Th, Cs, Vand Sc are also detected. The signature of Ce, La and Nd as light REEs is characterized in allsamples under this study. The enrichment types of (L-, M-type) and several distinct features ofsome REEs e.g., Ce and Eu anomalies are identified and described the signature of REEs in thegeochemical samples. These results are demonstrated as promising materials that could be usedfor metallurgy processing to get significant amounts of REEs.Corresponding author E-mail: dr.m.f.attallah@gmail.com & mohamed.attallah@eaea.org.eg12

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptUsing Scientific Techniques to Determine the Causes of Deterioration inQueen Nodjmet Mummy (a case study)Samia El-Merghaniphysical Anthropology, and conservator of mummies in Ministry of Tourism and AntiquitiesABSTRACTMummies are considered the most attractive and most sensitive organic artifacts inEgyptian antiquities. From conservation view, a great variety in mummification techniques andmaterials were found to be used through times and other variety within each period according tothe social level of the mummy’s owner. To determine the causes of deterioration, the external andinternal factors that may cause deterioration should be investigated. The external factors includeall microclimate surround the mummy and showcase/place of store. The external factor such asthe dating of the mummy and the materials used of embalming should be available. Each case isdifferent, so it is important to take sample/ swabs from the deteriorated areas for microscopicexamination and to perform the necessary analyses to identify the causes of damage and todevelop the treatment plan, then doing possible experiments before starting treatment on themummy.In this paper, the case study of the queen Nedjemet mummy is demonstrated and the causesof damage are defined using scientific analysis and applying suitable treatment. Good results areobtained and the conservation state is stable until now.13

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptCharacterization of Egyptian Human Renal Stones Using Chemical andRadiochemical TechniquesFatma H. El-Sweify*, Reham A. Hatab, Mohamed Ali, Wafaa S. HegazyHot Laboratories and Waste Management Center, Atomic Energy Authority, EgyptABSTRACTRecently, the incidence rate of renal stone disease is increased in Egypt. In addition toindustrial and environmental effects, trace elements may also have a role in the formation of suchstones in spite of their significance in biological lithogenesis. In this study, instrumental neutronactivation analysis (INAA) technique is applied for elemental analysis of some renal stones,collected from patients living in different provinces in Egypt. The samples are collected frommales, females and children, of different ages. The analyses are carried out under variousconditions of irradiation and cooling time. Major, minor and trace elements are determined.The analyzed elements are: As, Br, Ca, Co, Cr, Cu, Fe, Hf, In, Mg, Mn, Na, Se, Sr, Tb, Vand Zn. Some of these elements are biologically essential and others are dangerous or toxic.Firstly, 130 biological stone sample, from Al-Matrya National Institute of kidney andurinary tract at Cairo, have been obtained from patients of different genders and ages and livingin different locations. The analysis and investigations carried out on the collected stones aredirected to characterize these stones.The physicochemical analysis is carried out to determine the density of the stones and tostudy the effect of some organic solvent and inorganic acids on the dissolution anddecomposition of the different stones. The pneumatic irradiation rabbit system (PIRS) built in thevertical thermal column of the ET-RR-2 reactor is used for short time (200 seconds) irradiation at19 MW power.14

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptA Quantitative Approach to Groundwater Dating with TritiumW.M. Moustafa a , and F.H Abou El-Nour b*(a)(b)Egyptian Nuclear Regularity and Radiation Authority (ENRRA), EgyptNuclear Chemistry Department, Hot Laboratories Center, Atomic Energy Authority, EgyptABSTRACTThe age of groundwater represents an important factor for water resources management. Tritium asa radioactive isotope of hydrogen, with a half-life of 12.32 years and a mass of 3.01605 atomic mass unit(amu), becomes a standard for the definition of modern groundwater. The thermonuclear bomb testing inthe atmosphere, from May 1951 to 1976, provided the tritium input signal that defines modern water.Its decay from natural pre-bomb levels is such that it cannot normally be detected in groundwaterrecharged before 1950. Modern groundwater is then younger than about 45 years relative to the mid1990s. Tritium-free groundwater is considered "sub modern" or older.Isotope hydrology have been applied to investigate water resources, interconnection betweendifferent aquifers, relationship between surface and groundwater as well as recharge direction.Besides, the source, quantity and transport of pollutants, moisture and isotope fluxes in presentand past climate systems could be deduced. It is motivated by new and emerging interests intransit time estimation. In this paper, the methods available to estimate groundwater transit timeare discussed and a formal listing of sampling, aging and interpretation issues concerning thedevelopment and assessment of water resources are derived. Ground and surface water collectedfrom Nile-Delta and Greater Cairo aquifers to be used for drinking purposes were analyzed fortritium content, mean residence time, salinity and conductivity. The experimental results wereanalyzed, compared to each other, discussed and indicated the suitability of most of theseaquifers for drinking purposes, while others for irrigation.Corresponding author E-mail: fabunour2012@hotmail.com15

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptEvaluation of New-Modelled Recombinant Human Insulin (rh Insulin) AnalogExpressed in E.coli Using Radioiodination Technique Followed by In VivoBiodistribution in Diabetes Induced MiceGamal AbdelAziz* , Ibrahim.Y. AbdelGhany, Nasser. Farouk(1)Radiolabeled Compounds Department, Hot Laboratories Center, Egyptian Atomic EnergyAuthority, EgyptABSTRACTMany biological techniques are used by biologists to determine biological nature andphysiological activity of new mammalian proteins produced by recombinant DNA technology.Methods such as SDS-PAGE, western blot, ELISA and flow cytometry are commonly used,although these methods are considered to be of high cost and almost with comparatively lowefficiency, Therefore, the present research focuses on real-time studying the physiologicalactivity of new modelled recombinant human insulin produced in E.coli by studying itsBiodistribution after radiolabeling with 125I in mice with induced diabetes. Radioiodination takesplace for five-tyrosine residue in the structure of human insulin using the electrophilicsubstitution moiety, followed by optimizing the reaction by studying reaction factors includingamount of substrate, chloramine-T amount, pH, temperature and reaction time, in order to reach ahigh radiochemical yield of 99.01 0.2%. Previously induced Albino Swiss mice with diabetesusing streptozotocin (STZ) have treated with 125I - insulin to study the physiological activity andbiological functionality of the produced recombinant human insulin by studying itsbiodistribution behavior in diabetic mice. Results showed that The radioactive complex of 125I Insulin gives much better result after IV injection in diabetic mice, where no accumulation indistinct organ. An obvious reduction of glucose levels has been shown in mice blood, alsoclearance from both renal and hepatic route due to aqueous nature of insulin, Also prevalence ofinsulin in body according every organs mass or size, has a great impact of functionality ofrecombinant insulin molecule. Consequently, this method seems to be much rapid and effectivefor evaluation of biological molecule in vivo via radioactive tracing technique.Corresponding author Email: gamal abdelazeez@yahoo.com19

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptAccurate Calculations for 99mTc Eluted from 99Mo/99mTc Generators atDifferent Elution and Measurement TimesM. MostafaRadioactive Isotopes and Generators Department, Hot Laboratories Center, Atomic EnergyAuthority, EgyptABSTRACTIt is known that the radioactive growth-decay of99mTc as a daughter of99Mo follows atransient equilibrium, which is attained after 23 h. Routine production of 99Mo/99mTc generatorsbased on alumina requires a valid calculation model to predict the eluted activity ofcalibration date, from the measured eluted99mTc on99mTc activity at any time between production andcalibration dates. Time elapsed between: (i) conditioning and elution and (ii) elution andmeasurement should be taken into account. The article discusses the issue of using theapproximation used after attaining equilibrium and its effect on the accuracy of calculations. ATable is presented compiling ‘99mTc eluted fraction/elutedTc at tmax’ ratio against different99melution times which includes short time increments for more convenience and accuracy.20

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptTechnetium-99m Kits, The Black Horse of the Radiopharmaceuticals:Optimized Preparation and Bio-evaluationAbeer Mohamed AminLabeled Compound Department, Radioisotopes Production Division, Hot Laboratories Center,Atomic Energy Authority, EgyptABSTRACTThe widespread use of 99m Tc-radiopharmaceuticals depends on availability ofentirely pharmaceutical grade generators and the development of new 99m Tc radiotracers, withnovel drug having more favorable pharmacokinetic characteristics. Radiolabeling allowsnoninvasive imaging by single photon emission computed tomography (SPECT) or positronemission tomography (PET) for assessing the biodistribution of novel drugs. The efficacy of aradiopharmaceutical is determined by the type of ligand that it consists of, as well as theradionuclide that is incorporated in tracer amounts. The ligand may be an inorganic or organicmolecule, a peptide, an antibody or a more complex chemical structure with the ability toaccumulate in a pathological site in order to act diagnostically or therapeutically. The type ofemission of the radionuclide attached to the carrier gives the diagnostic or therapeutic characterto the radiopharmaceutical. An ideal radiopharmaceutical should concentrate in the tumor area inorder to afford the required result, with minimum radiation dose to healthy tissues.99mTc is oneof the most commonly used radionuclides for clinical SPECT imaging. Radiolabeled drugs canalso be used as tools for the estimation of novel drug pharmacokinetics in vivo. Morespecifically, accurate quantification of the amount of the labeled ligand in each organ, as well assimultaneous visualization of its route in vivo, can be determined21

A radionuclide generator is a concept defined as an effectiveradiochemical separation of decaying parent and daughter radionuclides such that the daughter isobtained in a pure radionuclidic and radiochemical form. Radionuclide generators werehistorically called ‘‘cows’’ since the daughter radioactivity was ‘‘milked’’ (i.e., removed) fromits precursor and the parent then generated a fresh supply of the daughter. Although manyparent/daughter pairs have been evaluated as radionuclide generator systems, there is relativelysmall number of generators, which are currently in routine clinical and research use. Essentiallyevery conceivable approach has been used for parent/separation strategies, including sublimation,thermo chromatographic separation, solvent extraction, and adsorptive column chromatography.The99Mo/99mTc generator system is the most widely used radionuclide generator forclinical applications.22

12th International Conference on Nuclear Sciences and Applications15-18 Feb.2016Hurghada - EgyptFeasibility Studies for the Implementation of Epithermal NAA at GHARR-1Bernard OseiNational Nuclear Research Institute, Ghana Atomic Energy Commission.ABSTRACTIn terms of utilization, the Ghana Research Reactor-1 (GHARR-1) facility is mainlyutilized for Neutron Activation Analysis (NAA). Throughout its years of operation, GHARR-1makes use of conventional NAA. Even though this type (variety) of NAA is useful in analysing awide range of elements, other varieties of NAA when employed will increase the scope ofelements that are analysed at the facility. This paper presents the results of the feasibility studieswith respect to neutronics carried out for the implementation of epithermal NAA at the GHARR1 centre using the Monte Carlo N-Particle code. For this variety of NAA samples are shieldedfrom neutrons in the thermal energy range and thus activated by epithermal neutrons. EpithermalNAA not only expands the number of elements that can be analysed but also allows for bettersensitivities and increased precision in quantifying elements.24
