Exploring the Impact and Applications of Nuclear Chemistry

1. Introduction to Nuclear Chemistry

Nuclear chemistry is a scientific subdiscipline that studies the transformation of matter given the addition or subtraction of subatomic particles. Given that the behavior of the atom is primarily affected by the arrangement of its electrons outside a very small and heavy nucleus, very little can affect the way that a chemical compound behaves other than a change in the arrangement of electrons. Physically, most of the way that the element behaves (density, melting temperature, boiling temperature) is due to the interaction of the electrons with each other and with the lattice of the solid more so than the interaction of the nuclei. The interaction of nuclear material with other elements is typically due to the ability of the element to lose or gain electrons to become more stable (like noble gases). Since the nucleus is so important to the identity of the element, and since it carries most of the mass of the atom, the properties of the nucleus can in some ways be seen as the properties of the element itself.

Nuclear chemistry is one of the most flexible and far-reaching fields of research. Many areas of research work with several compounds and varieties of the elements, but nuclear chemistry seeks to tap into the fundamental structure of the atom. Scientists working in this field often contribute to advances such as medical imaging, radiation therapy, nuclear energy, environmental science, and more. This collection of articles aims to demonstrate the range of topics and impacts that nuclear chemistry plays a part in, providing a broad overview of both current work in the field as well as relevant history. These topics are the result of cooperation between the variety of major laboratory and academic institutions who are on the cutting edge of nuclear science.

2. Fundamental Concepts and Principles in Nuclear Chemistry

Radioactivity is a special kind of nuclear chemistry. Throughout this article, we often refer to a reaction that simply changed one kind of atom into another as a nuclear reaction. But, true to form, the “nuclear” reactions studied in nuclear chemistry have proven to lead to a veritable Pandora’s Box of other, additional properties of matter and energy that are not known in other fields of chemistry. The most familiar of these special products of nuclear reactions, which we have already mentioned once, is radioactive atoms, which we will also touch on many times later down the page. Radioactivity is the special kind of nuclear reaction that we will turn to today. The first product is to produce radioactive isotopes, while the second is to induce and monitor radioactivity. In performing nuclear reactions, one also has the dual goals of (a) producing radionuclides and (b) optimizing the specific radioactivity (average decay rate at a choice of time) of the target radioisotope. The general problem is the simple one of finding a balance between these two competing goals: separating production and nuclear properties at optimized conditions. Nuclear reactions provide a second, albeit indirect, way of producing radioactive atoms using established, reliable, and repeatable methods. It is important to stress that, in principle, two very different, and differently weds, nuclear reactions could be used to produce the same radioisotope since the chemical and physical properties (number of electrons present in atomic orbitals, etc.) of radionuclides are determined by the total number of electrons present and not by the properties of the nuclear radiation emitted by the radionuclide.

Nuclear chemistry is the field of scientific study that aims to understand (a) how the atomic nucleus and its subatomic particles are configured, and (b) how to alter or modify those configurations through nuclear reactions, ultimately giving rise to new and previously unknown physical and chemical properties. The information, knowledge, and fundamental principles of nuclear chemistry underpin a remarkable range of the rare applications of nuclear-based technology that are routinely used in medicine, industry, pollution control, environmental clean-up and waste management, and scientific research at universities and other large public research facilities around the world. In most cases, the funding for, and/or coordination of, the research required to develop nuclear technologies is provided by governments or appropriate regulatory agencies.

3. Applications of Nuclear Chemistry in Medicine and Industry

In nuclear medicine, radioactive substances are used to image various parts of the human body. Generally, the radiation comes from a particular drug called a radiopharmaceutical, and is created using a radioactive isotope which is a variant of a particular chemical element such as carbon, technetium, xenon, iodine, and so on. Since the radioisotopes used in nuclear chemistry have very different chemical reactions from the normal atoms of the same type, the positions and amounts of the radiopharmaceutical in the body can be imaged and measured. This can be used to diagnose problems in the body as well as treat them by determining what is actually happening at the cellular level. Another application of nuclear chemistry is in the treatment of diseases like cancer, where devices are used to emit radiation for the purpose of slowing down and stopping the growth of the cancer cells through the emission of high-energy rays or particles. Nuclear chemistry also plays a vital role in industry, where it monitors and manipulates radioactive waste and chemicals used for scientific research. Nuclear chemistry assesses natural processes and synthetic using beams of the radioactive ion to prove correct theories of atomic structure. Nuclear chemistry uses radiation at coordinates, from which the size and location of the tumors can be identified which is useful in aiding radiation oncologists to monitor the effects of radiation on the tumors.

The applications of nuclear chemistry span across a number of industries, where the discovery of isotopes has played an extensive role in furthering our understanding of chemical composition, nuclear processes, the origin of the universe, and the behavior of stars. Though primarily associated with armaments and power generation, nuclear chemistry has numerous applications in the field of medicine and industry. Nuclear chemistry deals with the radioactivity in the human body, for applications like medical diagnosis and nuclear imaging. Medicinal radiochemistry focuses on metal complexes and probes the nuclear reactions that produce radionuclides useful in medicine. Specific uses of the applications of nuclear chemistry in medicine and industry include the fields of nuclear medicine, radiotherapy, and industry and agriculture.

4. Environmental and Ethical Considerations in Nuclear Chemistry

As a course of action, it is advisable to minimize societal reliance on ionizing-based technologies in favor of less harmful, non-ionizing radiation-based energy sources, to implement efficient and secure methods for the treatment and storage of nuclear waste, such as vitrification, safe disposal, and/or resale of disintegrating isotopes, as defined by authorities, and to further study the balancing of ionizing versus non-ionizing energy use. It is also important to employ only low-carbon energy that can be reused as a source of energy or by allowing some of the energy obtained during radioactive decay to carry out a chemical transformation. A highly cited scientific paper provides a favorable, ethical view of reusing and harvesting decay energy, as there is value in that the isotope effectively becomes a catalyst for the reaction, while the radiation continues to be used.

An important consideration in nuclear chemistry is the potential environmental impact of nuclear processes. While nuclear chemistry can, in some cases, provide a source of low-carbon energy, the waste products from such reactions and mining processes may have undesirable environmental consequences. Uranium mining has been shown to leach radioactive products into ground and surface water, posing significant health risks to those in the local region. There are also ethical concerns about whether to use nuclear decay energy to provide reliable low-carbon energy sources. By removing energy from decaying isotopes that would be produced by burning fossil fuels, it is possible to slow global warming. However, it is difficult to predict the consequences of both decisions, as high levels of ionizing radiation may be harmful to the environment and to humans.

5. Future Directions and Innovations in Nuclear Chemistry

3.3. Using radiation-induced polycondensation in the production of ion exchange materials. The radiation-induced polycondensation method presents spectacular results in the preparation of new ionizing radiations as they can introduce a new bifunctional link in the polymer chain and increase chain rigidity. This is a field worth thorough and detailed research, hence a lot of research on the effects induced by polymer irradiation of elements and other important glycols that form the basic monomeric structure of polyether IMS. In our laboratory, the first results of stability of these resins after irradiation with electrons stimulate the development of appropriate studies that can bring us closer to the final design.

3.2. Releasing and delivery of antimicrobial agents by nuclear particles. In recent years, scientists have focused their work on cancer therapy, primarily due to the significant increase in cancer incidence and the development of the effects of chemotherapy. However, some microorganisms showed increased resistance, which initiated the search for alternative antimicrobial agents, including the use of ionizing radiation to sterilize medical devices. Although radiation therapy by absorption in the skin of radiation releaseless particles and high-energy is not the first choice of non-invasive treatment of infectious disease, it can be efficiently applied to ignite a sterilization cascade.

3.1. Developing non-invasive diagnostic and treatment methods. In recent years, tumor-targeted nuclear therapeutic probes seem to be very promising in cancer therapy, provided that the specific antigens or tumor-targeted agents are used. Due to the high selectivity of biological delivery vectors and carrier-antigen interactions, and the decreased dose of radiation in normal organs and tissues, follow-up imaging by nuclear scan remains possible to monitor the biodistribution and pharmacokinetics of these delivery vectors. In addition, a number of nanocarriers intended to be applied for nuclear imaging have been approved for clinical use or in the experimental phase.
