Book excerpt: In this compilation, the authors examine the importance of ionizing radiations for thermoluminescence dosimetry that is the current area of research for medical and industrial purposes. Ionizing radiations are harmful to the human body, so, there is a need to measure small doses in the environment as well as very high doses at the time of accident like radiation leakage and for the treatment of cancer. Next, recent advances regarding effects on exposure of some foods to ionizing radiations are presented. The dosage required for complete sterilization may, at times, lead to undesirable changes in food flavours or may exceed the permitted levels. Combining irradiation with other treatments yields satisfactory results in these cases. Combined applications of ionizing radiation with heat, low temperature, high hydrostatic pressure, and modified atmospheres are also discussed. Later, new results concerning cell survival and genetic instability of wild-type and radiosensitive yeast cells of Saccharomyces cerevisiae surviving after irradiation with 60Co γ-rays, 239Pu α-particles and 254 nm UV light are presented. Survival was determined by cell ability to produce macrocolonies on a solid nutrient medium. The authors also review data on the radiation resistance of AlGaN/GaN and InAlN/GaN High Electron Mobility Transistors (HEMTs) as well as emerging Ga2O3 photodetectors and rectifiers to different types of ionizing radiation. Both of these wide bandgap semiconductor (nitride-based and gallium oxide-based) materials are much more radiation-hard than GaAs or Si and this is largely a result of their high bond strengths. By using the test system of blood lymphocytes of healthy individuals, the following paper presents the co-mutagenic (potentiating) effect of the drugs a calcium channel blocker verapamil and an antioxidant ascorbic acid-on the radiosensitivity of cells. It was found that when the lymphocytes are irradiated in a small dose (0.3 Gy), ascorbic acid (80.0 μg / blood) and verapamil (4.0 μg / ml blood) increase the frequency of chromosomal aberrations in comparison with the radiation effect by 75 and 62, 5% respectively. Afterwards, the experimental data of the effects of temperature, light intensity, background ionizing and non-ionizing radiation on physicochemical properties of water, water solution and cell function are presented. Considering the fact that the cell membrane permeability for water is more than 10 times higher than for inorganic ions, it is hypothesized that, upon the effect of chemical and physical factors, the changes of net water efflux through the membrane precede the activation of ionic fluxes in the membrane. Also in this compilation, a study is included which investigated the modifying effect of astaxanthin on radiation induced genome damages in cultivating human peripheral blood lymphocytes (PBL). The study indicated that astaxanthin in concentration of 20.0 �g/ml demonstrated evident radioprotective properties by reduction of the ChA level, decreasing of DNA damages and increasing of the apoptotic rate. In the last chapter, the authors present some works that study the causes of the high resistance of IRRB to ionizing radiation. Then we focus on presenting in silico approaches that use protein sequences of bacteria in order to predict if an unknown bacterium belongs to IRRB or ionizing-radiationsensitive bacteria (IRSB).

Available in PDF, EPUB and Kindle. Book excerpt: The industrial and medical applications of radiation have been augmented and scientific insight into mechanisms for radiation action notably progressed. In addition, the public concern about radiation risk has also grown extensively. Today the importance of risk communication among stakeholders involved in radiation-related issues is emphasized much more than any time in the past. Thus, the circumstances of radiation research have drastically changed, and the demand for a novel approach to radiation-related issues is increasing. It is thought that the publication of the book Evolution of Ionizing Radiation Research at this time would have enormous impacts on the society. The editor believes that technical experts would find a variety of new ideas and hints in this book that would be helpful to them to tackle ionizing radiation.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with comprehensive details on the management and measures to protect health against risks to people and environments generated by the use of ionizing and non-ionizing radiation. This book is divided into three sections, namely, Radiation Protection and Measurement; Radiation Therapy; and Radioactivity. The first section covers ionizing radiation protection; population exposure to non-ionizing density; and the system of dosimetry quantities for use in emergency preparedness and response to nuclear or radiological accidents. The second section covers various planning techniques for spinal stereotactic body radiotherapy and the application of radiation technology in the development of a malaria vaccine. The third section discusses environmental radioactivity monitoring using efficient measurements and the assessment of radiation exposure to humans. Also in this section is the evaluation of the effects of chronic radiation exposure on the testes of mice after a nuclear power plant accident.

Available in PDF, EPUB and Kindle. Book excerpt: The benefits of ionizing radiations have been largely demonstrated through many achievements of human life. Understanding the fundamental elementary interactions of ionizing radiations with material has allowed the development of various applications needed by different industries. This book draws some facets of their applications, such as hardening process for semiconductor devices, biomedical imaging by radiation luminescent quantum dots, hydrogen gas detection by Raman lidar sensor for explosion risk assessment, water and wastewater purification by radiation treatment for environment, doping by the neutron transmutation doping for the semiconductor industry, and polymerization by irradiation, which is useful for industries requiring resistant and protective coating. I wish the chapters of this book can provide some helpful information on ionizing radiation applications.

This book was released on 1996-04-08 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does radiation medicine need more regulation or simply better-coordinated regulation? This book addresses this and other questions of critical importance to public health and safety. The issues involved are high on the nation's agenda: the impact of radiation on public safety, the balance between federal and state authority, and the cost-benefit ratio of regulation. Although incidents of misadministration are rare, a case in Pennsylvania resulting in the death of a patient and the inadvertent exposure of others to a high dose of radiation drew attention to issues concerning the regulation of ionizing radiation in medicine and the need to examine current regulatory practices. Written at the request from the Nuclear Regulatory Commission (NRC), Radiation in Medicine reviews the regulation of ionizing radiation in medicine, focusing on the NRC's Medical Use Program, which governs the use of reactor-generated byproduct materials. The committee recommends immediate action on enforcement and provides longer term proposals for reform of the regulatory system. The volume covers Sources of radiation and their use in medicine. Levels of risk to patients, workers, and the public. Current roles of the Nuclear Regulatory Commission, other federal agencies, and states. Criticisms from the regulated community. The committee explores alternative regulatory structures for radiation medicine and explains the rationale for the option it recommends in this volume. Based on extensive research, input from the regulated community, and the collaborative efforts of experts from a range of disciplines, Radiation in Medicine will be an important resource for federal and state policymakers and regulators, health professionals involved in radiation treatment, developers and producers of radiation equipment, insurance providers, and concerned laypersons.
