The International Atomic Energy Agency (IAEA) is organizing the Second International Conference on Applications of Radiation Science and Technology (ICARST-2021), following the success of the first ICARST in 2017 (ICARST-2017). Since the discovery of X-rays and radioactivity more than 100 years ago, different ways to artificially produce radiation and radioactive materials were found. The studies of ionizing radiation and radioactive materials have led to dramatic advances in radiation science and technology, and they are used for a wide range of procedures in industry, agriculture, and research. Radiation technologies have been promoted for their merit in addressing important human needs, such as improving industrial production and processes; better managing scarce freshwater resources; improving human health and food safety; preserving cultural heritages; and protecting our environment.
Numerous innovations and accomplishments in the field of radiation sciences have been already acknowledged, however it is now time to take a comprehensive look at their status in academia and industry, as well as their ability to meet future challenges. Radiation scientists are currently addressing issues related to producing advanced high performance materials through ‘green’ industrial processes to ensure cleaner environment; attaining a thorough understanding of the chemical effects of radiation under special conditions (which is important for material science in nuclear energy field, for studies of stability and compatibility of irradiated products in the human body, and for other applications); and investigating novel approaches to address the complicated chemistry at interfaces. Radiation technologists, on the other hand, are faced with other challenges, such as ensuring the safe and reliable operation of radiation facilities, implementing requisite international standards for process control, ensuring the continued supply and transport of cobalt-60 consignments across continents, and developing a new generation of high power electron beam accelerators and X-ray sources for emerging applications. https://www.iaea.org/events/icarst-2021
