Basic Radiation and Nuclear Physics The realm of nuclear physics brought major impact to the technological advancement that influences the society where we live today. From the discovery of nuclear power to the creation of nuclear weapon and age estimation of historical artifacts through radiocarbon dating, the applications of nuclear physics provided significant changes to the global modernization. The technological applications of nuclear physics require the skills and knowledge of chemical engineers especially in energy industry like nuclear power plants. In this meeting, we have learned the basic concepts on radiation and nuclear physics. These include the nuclear, fission, nuclear fusion, uses of isotopes and biological effects of radiation. The discussion highlights the difference between nuclear reaction and chemical reaction. In chemical reactions, only electrons are involved in the breaking and forming of bonds while in nuclear reactions, the protons, neutrons and electrons may be involved. Another topic discussed is nuclear stability. Nuclear stability suggests that the nucleus of an element is stable; hence, it does not decay. It was mentioned that nuclei with even numbers of both protons and neutrons are more stable than that with odd number of protons and electrons. Nuclear fission and fusion were also explained during the meeting. From the word itself, nuclear fission means splitting of nucleus into 2 nuclei while nuclear fusion happens when 2 nuclei combine releasing huge amount of energy. The application of nuclear radiation in medical technology and food preservation was also discussed. Furthermore, the proper handling and disposal of hazardous wastes was raised during the meeting. Nuclear physics has a wide array of applications that require the skills of chemical engineers. In wastewater treatment, radiation technology is used wherein wastewater are exposed to gamma rays to eliminate harmful microorganism. Similarly, food irradiation technology provides safety and extends the shelf life of most food by eliminating microorganisms. This technology is commonly used in manufacturing of milk and other dairy products, and canning of foods and vegetables. In medical field, on the other hand, radiation therapy utilizes immense radiation to kill cancer cells and reduces the size of tumors. These applications that have significant contribution to the modernization rely on people who are experts in the field of nuclear physics including chemical engineers. As a chemical engineering student, these ingenious applications drive me to have a deeper understanding on the world of nuclear physics.
