Abstract:
The construction of radiation shielding buildings still developed. Application of ionizing radiations became necessary for different reasons, like electricity generation, industry, medical (therapy treatment), agriculture, and scientific research. Different countries all over the world moving toward energy saving, besides growing the demand for using radiation in several aspects. Nuclear power plants, healthcare buildings, industrial buildings, and aerospace are the main neutrons and gamma shielding buildings. Special design and building materials are required to enhance safety and reduce the risk of radiation emission. Radiation shielding, strength, fire resistance, and durability are the most important properties, cost-effective and environmentally friendly are coming next. Heavy-weight concrete (HWC) is used widely in neutron shielding materials due to its cost-effectiveness and worthy physical and mechanical properties. This paper aims to give an overview of nuclear buildings, their application, and behaviour under different radiations. Also to review the heavy-weight concrete and heavy aggregate and their important role in developing the neutrons shielding materials. Conclusions showed there are still some gaps in improving the heavy-weight concrete (HWC) properties.

Abstract:
Electric and electronic devices are mainly emitting electromagnetic radiation, and shielding from radiation is essential. Electrically conductive materials are suitable for radiation shielding applications. The designing of the textile material for the radiation shielding is challenging because of its open area and design. In general, more open area has transmit the radiations tend to lesser in shielding. Another factor is the laying angle of the textile material also plays important role beyond open area. In this study, the effect of laying angle and open area was analysed for effective utilization of conductive materials. The conductive nonwoven fabric was used to form as strips to simulate the various textile structures for shielding application. The Cu/Ni coated ultrathin polyester nonwoven fabric sample is taken to form two-layers strips and test for electromagnetic shielding effectiveness. In experimental design, three factors of strips which are strips laid angle, strip thickness, and gap between the strips are taken at three levels. The strip cover area and aperture area were calculated geomentrically for each design and significant difference on shielding effectiveness was noticed.

Abstract:
With the increasing applications of nuclear technology, radiation protection has become very important especially for the environment and the personnel close to radiation sources. Natural clays can be used potentially for shielding the X-ray radiations. In this study, the correlation between structural parameters and radiation shielding performance of natural clay extracted from Algerian Sahara (Adrar, Reggan, and Timimoune) was investigated. Phase composition and structural parameters (lattice parameters, average crystallite size, and microstrain) were determined by the Rietveld refinements of X-ray diffraction patterns in the frame of HighScore Plus software. The obtained results showed that the studied clays are nanocrystalline (nano-clay) since the calculated crystallite size was ≈3 nm for the feldspar phase. FTIR spectra confirmed the presence of all phases already detected by XRD analysis besides Biotite (around the band at 3558 cm−1). The remaining bands corresponded to absorbed and adsorbed water (3432 cm−1 and 1629 cm−1, respectively) and atmospheric CO2 (2356 cm−1). The shielding properties (mass absorption coefficient—µ/ρ and radiative attenuation rate—RA) for (green-yellow, green, and red) clays of Adrar, (red, white, and white-red) clays of Reggan, and red clay of Timimoune at same energy level were examined. The results of clay samples were compared with each other. The obtained results indicated that the green clay of Adrar exhibited the superior radiation shielding, i.e., 99.8% and 243.4 cm2/g for radiative attenuation rate and mass absorption coefficient, respectively.

Abstract:
To meet the requirements of integrative mechanical properties and shielding effectiveness of nuclear radiations shielding materials, the boron-rich shielding coating (Fe67.5Ni23.5B9, in wt. %) were produced onto 321 stainless steel substrate (SS) by the air-plasma spraying technology. This type of coating-SS laminated composite will be likely to be used as protection against neutrons and γ rays from radiation shielding systems. The microstructure was characterized by scanning electron microscope (SEM), energy-dispersive spectrometry (EDS) and X-rays diffraction (XRD). The mechanical properties of Fe67.5Ni23.5B9 coatings were investigated, including adhesion strength, tensile properties and residual stress. The shielding effectiveness of the coating-SS laminated composite, including the slowing down of fast-speed neutrons, absorption for 0.4ev below thermal neutrons and the attenuation against 60Co and 137Cs γ rays were investigated. The results show that the produced Fe67.5Ni23.5B9 coatings-SS laminated composite possess homogeneous microstructure, satisfactory integrative mechanical properties and shielding effectiveness which testify the possible application in radiation shielding systems.

Abstract:
.In order to design better anti-radiation and electromagnetic shielding fabric and the clothing and makes it maintained better of electromagnetic shield effectiveness, the influence of radiation source, radiation distance, anti-electromagnetic radiation material, fabric structure, gap size, holes area, clothing exposed area as well as the tunnel effect and so on the fabric radiation protection performance were comprehensively discussed in this article. As well, according to these influence factor analysis the regular conditions that the electromagnetic shielding fabric and garment design should be meet. The analysis result indicated that the shielding effectiveness of the fabric was decreased with the increase of the radiant frequency, the fabric slit size, the hole area and enhanced with the growing of the metal content, the organizational structure close degree as well as the radiation distance.In the case of the equal shielding effect, the bigger exposed area leads weaker electromagnetic shielding effectiveness and if the exposed area oversize can cause the shield effect vanished. Also the clothing shield potency was related to the opening radius, the length, the inside and outside dielectric constant, the permeability of the shirt or cuff. The comprehensive effectiveness of electromagnetic shielding fabrics will be gradually improved if they can meet these regular conditions continually.

Abstract:
Radiation exposure in medical institutions is mainly due to low doses. Low-dose radiation mainly means scattered radiation, and such scattered radiation can be shielded with a lightweight shielding suit. In this study, the shielding performance of shielding fabrics woven by winding polyethylene (PE) yarn around a 30 μm tungsten wire was evaluated. To improve the shielding performance, an air pressure dispersion process of coating tungsten nanopowder on the fiber was developed. The radiation shielding effectiveness of the shielding fibers with and without dispersed tungsten nanopowder were compared by measuring the spatial dose inside the diagnostic X-ray imaging room of a medical institution. The results of the experiment confirmed that the fabric coated with tungsten nanopowder improved the shielding performance of the general tungsten fiber by approximately 15% and provided relatively effective low-dose radiation shielding at approximately 1.2 m of the X-ray imaging equipment. This study shows that tungsten fiber can be helpful in manufacturing lightweight shielding clothing for protection from scattered radiation in medical institutions.

Abstract:
Abstract Radiation shielding materials are essential for various applications in space exploration, nuclear power plants, and medical devices. In this study, we present a theoretical design of radiation shielding nanocomposites based on a combination of TiO2-SiO2-Fe3O4-B4C-Al2O3 materials. Using the Phy-X/PSD, EpiXS, and XMuDAT programs, we calculated the radiation shielding properties, including mass attenuation coefficient, mean free path, and effective atomic number, of a series of nanocomposite structures with different Fe3O4 and B4C contents. Our results show that the addition of Fe3O4 and B4C to nanocomposites enhances the radiation shielding efficiency and the maximum shielding is observed in the nanocomposite with the highest density. The theoretical calculations also reveal that the proposed nanocomposites have excellent radiation shielding properties compared to conventional shielding materials, such as lead and concrete. This work demonstrates the potential of using a computational approach to design novel radiation shielding nanocomposites with improved performance, which could have significant implications for a wide range of applications.

Abstract:
This thesis discusses the development, benchmarking and applications of activation dose analysis methods for fusion devices. The development and code logic of the Mesh Coupled Rigorous 2 Step (MCR2S) system is discussed. Following the development of the code, appropriate benchmarking studies were performed on the Frascati neutron generator, and revealed that the code was able to predict shutdown gamma ray doserates to within ±3% of experimentally determined values, for decay times between 3×105 and 107 seconds. The development of the Ion Cyclotron Resonance Heater (ICRH) with regards to neutronics was discussed. The ICRH went through a number of design stages and shutdown gamma ray dose rates were determined for each stage. It was determined that of all the designs analysed only one of them, the first concept design for the internally matched design did not meet the shutdown dose criteria. This was due to a flaw in the system design, brought about by a lack of consideration towards nuclear design. The ITER Light Imaging Detection and Ranging (LIDAR) system was subjected to a full shutdown nuclear analysis. It was found that the design of the LIDAR system supplied did not meet the ITER required shutdown gamma ray dose rate limit of 100 µSvhr−1, however use of the MCR2S system highlighted the components that contributed most to the shutdown gamma ray dose rate and were shown to be the mirror holder and the laser beam pipe. Future designs should include additional shielding around the beam pipe.

Abstract:
Beyond the protective confines of Earth's atmosphere and magnetosphere, spacecraft are subject to constant bombardment by high-energy charged particles originating from our Sun in the form of Solar Particle Events (SPEs), and from outside the solar system in the form of Galactic Cosmic Rays (GCRs). The harm these particles do can be reduced or mitigated outright through radiation shielding. Because protons and other charged particles comprise most of these radiation particles, strong magnetic fields could be generated around spacecraft to deflect incoming charged radiation particles. This thesis investigates the performance of specific configurations of toroidal superconducting solenoids to generate magnetic fields that deflect incoming energetic protons via the Lorentz force. Bulk material shielding configurations using various thicknesses of liquid water are similarly investigated, as are combination shielding configurations combining the best-performing toroidal shielding configurations with a small bulk material shield surrounding the spacecraft. The water shielding configurations tested included shields of uniform thicknesses from 1 cm to 10 cm surrounding an Apollo CSM-sized cylindrical candidate spacecraft. Water shielding was found to be very effective at reducing the SPE dose, from a 86\% reduction at 1 cm of water to a 94\% reduction at 10 cm. However water shielding was found to be minimally effective against the much higher energy Galactic Cosmic Ray protons, with no dose reduction at 1 cm and a paltry 1\% reduction at 10 cm. The toroidal shielding geometric configurations tested consisted of either 5 or 10 primary toroidal shields surrounding the candidate spacecraft, as was the addition of smaller nested toroidal shields inside the primary toroids and of toroids on the spacecraft's endcaps. The magnetic field strengths tested were 1.7 Tesla, 8.5 Tesla, and 17 Tesla. The best geometric configurations of electrodynamic shielding consisted of 5 primary toroidal shields, 5 total nested shields placed inside the primary toroids, and 2 total shields on the spacecraft's endcaps. The second best geometric configuration consisted of 10 primary toroidal shields plus two total endcap shields. These configurations at 1.7 Tesla reduced the SPE dose by 87\% and 87\%, and reduced the GCR dose by 11\% and 10\%. At 17 Tesla, these configurations both reduced the SPE dose by 90\%, and reduced the GCR dose by 76\% and 61\%. Combining these two configurations with a 1 cm-thick shield of water improved performance against SPE protons to 95\% and 93\% at 1.7 Tesla, and a 97\% and 96\% reduction at 17 Tesla. GCR dose reductions decreased slightly. Passive material shielding was found capable of providing substantial protection against SPE protons, but was minimally effective against GCR protons without very thick shielding. Electrodynamic shielding, at magnetic field strengths of 1.7 Tesla, was found to be similarly effective against SPE protons, and marginally more effective against GCR protons. Combining the best toroidal shielding configurations, at magnetic field strengths of 1.7 Tesla, with water shielding yielded high protection against SPE protons, but still marginal protection against GCR protons. Increasing the magnetic field strength to 17 Tesla was found to provide very high protection against SPE protons, and to significantly reduce the radiation dose from GCR protons. Of all shielding configurations tested, only those electrodynamic configurations with magnetic fields of 17 Tesla were able to reduce the GCR dose by more than half.

Abstract:
This paper focused on two significant space forces that can affect the success of a spacecraft: the radiation and micrometeoroid environments. Both are looked at in the context of the region of space between Earth and Mars. The goal was create reference environments, to provide context to results of environmental modeling, and to provide recommendations to assist in early design decisions of interplanetary spacecraft. The radiation section of this report used NASA's OLTARIS program to generate data for analysis. The area of focus was on the radiation effects for crewed missions, therefore effective dose equivalent was the metric used to compare different models of radiation and shielding. Test spheres with one, two, or three different materials layers were compared, along with modifiers such as alloys or weight vs. thickness emphasis. Results were compared to limits set by the European and Russian Space Agencies to provide context. The results hinged heavily on the intensity of the Solar Particle Events (SPEs), with testing using additional temporary radiation shielding proving to be a requirement for feasible shielding masses. Differences in shield material effectiveness were found to be negligible for thin Galactic Cosmic Rays (GCRs) and thick SPEs. Thick shields were found to perform better when the more efficient shield was on the outside of the test sphere. The micrometeoroid section used equations and programs from multiple sources to generate state vectors, flux, and finally impact models for four different case studies. Impacts v were generated with mass, velocity, and impact angle/location statistics. The mass and velocity results were run through statistical software to generate information such as mean and standard deviation with confidence intervals. Also looked at were higher mass impacts, limited to above 10-3 grams as opposed to above 10-6 for the regular case. The results of this show that very thin monolithic shields (0.1 cm-0.25 cm) could protect against the average 10-6 impact. The Ram, Nadir, and Anti-sun faces received the highest quantity of impacts and Wake received the least. When looking at the worst cases average mass and velocity for the high mass impacts significantly higher shielding was required to prevent penetration (up to 5 cm for some cases). However, the test cases had probabilities of no high mass impacts greater than 46% of the time, with shorter mission having greater chances of no high mass impacts.

Abstract:
Space radiation is one of the main showstoppers for human exploration of deep space. When leaving the protection provided by Earth’s atmosphere and magnetic field, the astronaut crew find themselves immersed into a complex radiation field, originated by the interaction of different high-energy radiation sources with the spacecraft’s walls, and characterized by many particle species with a broad range of energies. The biological effects of the long-term radiation exposure is largely uncertain and could give rise not only to late solid cancers and leukemia, but also to early effects to cardiac and nervous tissues, possibly undermining mission success. An available countermeasure to defend the astronauts from radiation is passive shielding, i.e. the interposition of shielding materials between the radiation sources and the exposed subjects. However, the majority of space radiation is practically impossible to completely stop: the high energetic particles constituting the space environment have the capability to penetrate several meters of materials, generating a harmful component of secondary particles, further contributing to the radiation dose. The ability of a material to attenuate the incoming space radiation and the nature of the generated secondary particles largely depends on the traversed material itself, in particular on the ratio between its charge and mass atomic numbers, Z/A. The lower is this ratio, the higher the material’s capability to attenuate the incoming radiation will be, both through electromagnetic and nuclear interactions. While the radiobiology community is focusing on the biological effects, radiation physics is trying to lower uncertainties characterizing the radiation interactions with materials, performing radiation measurements of various nature. In this framework I focused my PhD activity on the study of materials which could be used in space as shielding layers and multipurpose structures have been evaluated and selected under different criteria. At first, their ability to shield different kinds of space radiation were calculated with the aid of 1D Monte Carlo simulations, also followed by an evaluation of their structural and thermal proprieties, cost, availability and compatibility with the space environment. Simulations, in particular, were performed both to support the material selection process both to produce guidelines for design. The selected materials were then procured to be tested under different radiation beams and different set-ups, in single and multi-layers configurations, in an attempt to reproduce space exposure conditions. At the same time, the radiation tests have been reproduced by means of Monte Carlo simulations, to compare the experimental results and the simulations’ outputs, confirming the codes’ ability to reproduce radiation measurements involving High Z-number and high Energy (HZE) particles. For some materials, suggestions were provided on which nuclear model was better reproducing the data. The performed experimental campaign suggested that a candidate shielding material suitable for Galactic Cosmic Rays (GCR) should be tested with at least two beams with different characteristics, since the results indicated that some materials good at shielding 972 MeV/nuc 56Fe ions performed very poorly when irradiated with high energetic alphas. Furthermore, among the material types included in this investigation work, Lithium Hydride resulted the best option to stop space radiation, when only radiation shielding properties are considered. At the end of the experimental campaigns, on the basis of the test results, a 3D simulation activity has started and is still on-going and a modular space habitat model has been created. Monte Carlo simulations have been carried out, reproducing different Moon exposure scenarios with the goal of calculating crew radiation exposure during a Moon surface mission. This work reports results only for a standard aluminum habitat, with only Moon soil used as shielding material. However, future simulations will include Lithium Hydride and possibly others materials as shielding layers, to evaluate their effectiveness in reducing the dose in a realistic exposure scenario. Preliminary results show that even with a heavily shielded spacecraft (the habitat taken in consideration in this work is providing from every direction at least 30 g/cm2 of aluminum equivalent) radiation exposure approaches values close to the existing annual radiation exposure limits. Part of this thesis’ work was done at Thales Alenia Space, using Thales Alenia Space infrastructures and in the framework of the ROSSINI2 study. The ROSSINI2 study has been supported by European Space Agency (ESA) under the contract RFP IPLPTE/LF/mo/942.2014 and with the generous support of NASA and BNL, providing beam time at the NSRL facility.

Abstract:
Abstract Radiation exposure is an essential measure of social welfare. Every day the public was exposed to radiation, whether they were aware of it or not. Public people can only receive no more than 1mSv of radiation in a year based on Basic Safety Radiation Protection Regulations 2010 under Atomic Energy Licensing. If it exceeds the value, it may risk people’s health and well-being. People are constantly exposed to radiation sources that exist naturally in everyday life. Without any action taken, the radioactive sources might penetrate people’s bodies. A shield is needed to avoid these unnecessary radiations. However, radiation shield are not comfortable to use daily. Thus, the main objective of this experiment is to observe the effectiveness of a commonly available object as a radiation shield. These objects can be found easily daily and used as a radiation shield. Gamma sources that are used in this experiment is 241Am and 133Ba. Solid-state detectors are used to measure the counts. The experiment shows positive feedback from glass, dark glass, brick, clay, and battery. They can shield gamma rays effectively. The main element of these objects is observed to see how the elements affected the objects’ ability to shield gamma. Carbon, oxygen, sulphur, hydrogen, and zinc can be used as the main elements to produce radiation shielding. The supervisor continuously monitored the execution and the safety during the experiment.

Abstract:
Cemented tungsten carbides (cWC)s are attractive radiation shielding material candidates, from their high density, ease of manufacture and excellent mechanical properties. Recent research indicate that cWCs can have better radiation shielding behaviour compared to conventional candidate materials. The application of tungsten carbide as a radiation shielding material is not well understood due to the use of highly activating Co and Ni as the main binder alloys and are still lacking in the literature. cWCs are of particular interest since the mixture of high and low Z-elements offers effective shielding against gamma and neutron radiation, photons, and fast neutron capture/removal cross section. The presence of carbon in cWCs contributes to the moderation of fast neutrons flux, reducing their contribution to total dose rate. In this paper, tungsten carbide applications in nuclear power and nuclear medicine are reviewed. The key challenges and further research for the future direction are highlighted.

Abstract:
One of the major concerns in long duration space exploration is to minimize the exposure of crew and equipment to space radiation. High energy radiation not only can be hazardous to the health but also can damage the materials and electronics. Current designs are contained heavy metals to avoid occupational hazards from radiation exposures. As a result the shielding structures are heavy and not effective to attenuate all types of radiation. Therefore, the proposed lightweight sandwich composites are designed to effectively shield high energy radiations while providing structural integrity. In the manufactured hybrid sandwich composite, High Molecular Weight Poly Ethylene (HMWPE) woven fabrics are selected as face sheets due to their advanced mechanical properties and excellent physical properties along with effective shielding properties. Basically polymers due to high hydrogen content are considered as effective materials to attenuate high energy radiations. In addition, the core material is epoxy composites incorporating three weight percentages of three different nanoparticles viz. Boron Carbide, Boron Nanopowder and Gadolinium. In fact if polymers as low Z materials are used alone, they usually are not successful to attenuate highly penetrative rays. Therefore, one solution is known to infuse polymer matrix with high radiation absorption properties nanoparticles. Among several different nanomaterials, the three aforementioned nanofillers were chosen because of their good radiation absorption properties. Gadolinium has the highest thermal neutron cross section compare to any other known element and 10B-containing materials are known as excellent radiation absorbers and the composite filled with them have the advantage of convenient and safety in construction, operation and reintegration. The sandwich composites were manufactured using Heat-Vacuum Assisted Resin Transfer Molding method (H-VARTM), which is a cost effective method for high volume production of sandwich structures. To evaluate the shielding performance of manufactured sandwich panels the neutron attenuation testing was performed. The results from neutron radiation tests show more than 99% shielding performance in all of the sandwich panels. In comparison with other nanofillers, Boron Nanopowder showed highest radiation shielding efficiency (99.64%), which can be attributed to its lowest particle size and better dispersion ability into epoxy resin. The flatwise compression testing was performed on all four sandwich panels to determine the mechanical strength of materials before and after being exposure to radiation. The results demonstrate that proposed hybrid sandwich panels can preserve their mechanical integrity while being exposed to the radiation.
