Food Irradiation Technologies

Languages : en
Pages : 454
Book Description
Food preservation by irradiation is gaining recognition as a technology that is more environmentally benign than other current processes such as post-harvest chemical fumigation, it has less impact on thermally sensitive compounds than thermal decontamination technologies such as hot water or steam, and the technology is more accessible and cheaper. As the technical and economic feasibility, as well as the level of consumer acceptance, have increased its use has been growing fast. International organizations including the Food and Agriculture Organization of the United Nations (FAO), the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO) have coordinated and worked with others to develop norms and review the safety and efficacy of irradiated foods. Commended in the Foreword by Carl Blackburn, Food Irradiation Specialist, Joint FAO / IAEA Division of Nuclear Techniques in Food and Agriculture, this book makes a strong case for the use of this overwhelmingly safe food processing technique. This comprehensive book is a useful reference for food technologists, analytical chemists and food processing professionals, covering all aspects of gamma, electron beam and X-ray food irradiation, its impact on food matrices and microorganisms, legislation and market aspects. It is the first book to cover control and structural analysis in food irradiation and, being written by leading experts in the field, addresses the current global best practices. It contains updated information about the commercial application of food irradiation technology, especially regarding the type of radiation based on food classes and covers dosimetry, radiation chemistry, food decontamination, food quarantine, food processing and food sterilization.
Effects of Gamma Radiation and Low Energy Electrons Beam on Semiconductor Thin Films

Book Description
Research work has been continuously dedicated by the scientific community to improve or optimize the physical properties of thin films. In this present book, we bring into the attention an important research axis developed in our research group, i.e. the use of irradiation with intense gamma radiation and electron beam energy with the aim to improve and customize the structural, optical, morphological and electrical properties of thin film semiconductors for space and terrestrial photovoltaic applications, dosimetry of ionizing radiation and photocatalysis for the depollution of water contaminated by organic dyes. The number of worldwide scientific contributions and publications in this area of research is considered low compared to other research areas, hence the desire to contribute to developing and enriching this research area of thin film semiconductors. Our work was carried out in collaboration with the National Center for Nuclear Sciences and Technologies (CNSTN) in Tunisia, which owns the industrial equipment for gamma irradiation. An agreement was signed between the LPMC (define LPMC) laboratory and the CNSTN to carry out several gamma irradiation campaigns for several types of materials. Another collaboration was made with the COFICAB industrial company that produces electric cables, which is a subsidiary of the CHAKIRA group, to offer us an electron beam time with their low energy electron accelerator. Irradiation by ionizing radiation is widely used in food preservation to extend their storage or marketing periods and also for the sterilization of medical products. Among the outstanding industrial applications of electron beam irradiation is its use to improve the physical properties of the polymers making up the sheaths of electrical cables. In fact, the electrons emitted by the accelerators entrain free radicals in the polymers, the recombination of which leads to an improvement in their resistance to the high temperature of fires and to harmful solvents. In addition, many research works use irradiation to study the resistance of materials to intense nuclear radiation or to increase their life spans and for certain other materials to strengthen their nuclear waste storage capacities. Hence our motivation to use gamma radiation or electron beam irradiation to try to find improvements in the physical properties of semiconductor thin films used in the photovoltaic field or photocatalysis. Indeed, irradiation could be considered as a powerful tool to modify in a controlled way the electrical, structural, optical and morphological properties of these thin films. The choice of materials was motivated by their role played in optical windows, absorbers or buffer layers, which are commonly used in the new generation of photovoltaic cells. The two families of materials are the transparent conductive oxides (TCO), such as Fe-doped In2O3, and sulfur-based compounds, such as In2S3, Cu2ZnSnS4 and Sm-doped CaSO4. The synthesis and growth of these materials have been developed and optimized in our LPMC laboratory through previous research works. To the best of our knowledge, our work on the irradiation of thin films by gamma radiation of thin films of Cu2ZnSnS4, In2S3 and In2O3 doped with iron and fluorine is novel and the results are of great interest for the scientific community. The main objective of applying irradiation is to systematically control and improve the structural, optical, morphological, or electrical properties of thin films by applying very precise doses of gamma radiation or electron beams. Irradiation can cause structural defects in crystal lattices, generate excitations, change, or transform energy levels or even break atomic bonds, which can be used to tailor the properties of thin film semiconductors for specific applications.

Book Description
The irradiation of metallurgical test specimens in the beam port and fuel core facilities of various nuclear test reactors at temperatures ranging from 200 to 800 F has necessitated the design and development of several temperature control systems. Basic systems which have been employed for the irradiation of relatively massive loadings in the various experimental facilities of the Brookhaven Graphite Reactor and the Oak Ridge Low Intensity Test Reactor are described in detail and reference made to inherent system advantages and limitations.

Book Description
Quality control in pharmaceutical products and medical devices is vital for users as failing to comply with national and international regulations can lead to accidents that could easily be avoided. For this reason, manufacturing a quality medical product will support patient safety. Microbiologists working in both the pharmaceutical and medical device industries face considerable challenges in keeping abreast of the myriad microbiological references available to them and the continuously evolving regulatory requirements. Quality Control Applications in the Pharmaceutical and Medical Device Manufacturing Industry presents the importance of quality control in pharmaceutical products and medical devices, which must have very high-quality standards to not cause problems to the health of patients. It reinforces and updates the knowledge of analytical, instrumental, and biological methods to demonstrate the correct quality control and good manufacturing practice for pharmaceutical products and medical devices. Covering topics such as pharmaceutical nano systems, machine learning, and software validation, this book is an essential resource for managers, engineers, supervisors, pharmacists, chemists, academicians, and researchers.
