Abstract
Hot atom chemistry, a pivotal subfield of radiochemistry, investigates the chemical behavior of atoms with high kinetic energy produced during nuclear transformations. Since its inception in the mid-20th century, this field has provided profound insights into reaction mechanisms and atomic interactions under extreme conditions. Historically, the understanding of chemical effects induced by recoil atoms from nuclear reactions was instrumental in elucidating the behavior of radioactive isotopes, influencing nuclear fuel reprocessing and radiopharmaceutical development. In the present era, hot atom chemistry finds applications in diverse domains. Advanced methodologies, such as pulse radiolysis and time-resolved spectroscopy, enable detailed kinetic studies of transient species formed in recoil processes. The field has also contributed significantly to targeted alpha therapy, where recoil atoms are utilized for precision oncology treatments. Additionally, the synthesis of novel materials through high-energy irradiation processes exemplifies its industrial relevance. Looking ahead, the future of hot atom chemistry promises exciting directions. Emerging techniques in ultrafast spectroscopy and computational modeling are expected to deepen our understanding of high-energy atomic interactions. Integration with nanotechnology may lead to the design of innovative materials with applications in energy storage and catalysis. Furthermore, expanding the scope to environmental monitoring and sustainable nuclear technology underscores its role in addressing global challenges. This presentation will explore the transformative journey of hot atom chemistry, highlighting its historical milestones, current applications, and future potentials in advancing science and technology. The continued evolution of this field underscores its significance in modern scientific exploration and societal impact.
